  1. (When the base and any other digital creations are built in real life, I will add those pictures into this page.) This is the beginning of a journey through the wormhole to a mini-figure called Benny and a civilization on the cusp of greatness. His continuing mission: to seek out new lifeforms, to explore unknown worlds, all in the name of of science and awesomeness. The year is 1980-something, the name of the theme is Classic Space. Classic Space fortress walls The base as it was ordered... will post a picture of the complete setup when built in real life. Here is the base's main gate. It can open up all the way to allow the ground vehicles though, including the road train. (Conveyex) The gate fully closed. This is one of twelve walls sections, held together with the other modules by four Technic pins.(two on each side) This is one of four of the corner modules. I redesigned these since last time to be less parts intensive and have fewer gaps in the wall. Classic Space HQ / Benny's skyscraper - 76038 MOD I was inspired to build this model by set 76038. (Attack on Avengers Tower) from 2015. I turned it into a Classic Space skyscraper, specifically one for Benny's HQ. This one was designed with it's ultra-sleek feel and wraparound window on the top floor for Benny's office, overlooking the whole space base which he commands, which also conveniently hooks into the walls of the building at the base. The street-side of the building features the canopy-covered front door with the year that Classic Space was started emblazoned on the top row of studs. (1978, labeled in printed 1 x 1 tiles) Slightly above that is the CS logo piece as seen here. The two upper most floors are Benny's office and then the memorabilia room, featuring Benny's original broken helmet and a golden Space Paranoids high score trophy. (Benny won several competitions in the late 1980's after being coached by game master / inventor Kevin Flynn.) There is also supposed to be the trans-dark blue Space infinity stone in there for safekeeping, but the Avengers needed it recently, so he gave it back and is patiently waiting for it's eventual return to him. The next three floors down are where the computers that control the rooftop radio antenna dish are situated. They all look the same so only one is shown. Classic 1970's Moonraker muscle car This eight-wide Classic Space model was loosely based upon cobbled-together hot rod in set 70829 (Emmet and Lucy's Escape Buggy!) from the LEGO Movie 2 - the second part. I have reconfigured the car's front end (the only part I kept mostly intact from the set) for use with Benny the 1980-something space guy, and added trans-yellow windows, a blue + light gray paint scheme, with additional black / yellow bumblebee stripes for good measure. I have removed the set's wild suspension, and added a more tame rear half to better match the front portion. This looks (to me) like a late 1970's muscle car, of the same time frame when Classic Space launched in 1978. The car also has two side mirrors, red wheels, opening passenger cabin doors, and a license plate in the back instead of the original huge engine and jet booster exhaust outlet. I also added in a Jack Stone spoiler piece because, why not? Classic 1980's Security Forces Jeep (x2) This model was heavily inspired by set 75916: Dilophosaurus Ambush from the first series of Jurassic World sets. I have turned that jeep into a Classic Space vehicle by subtracting most of the features and adding the CS logo to this piece on the trunk and a space seat for the driver. This CS version has a trans-yellow windscreen and a revised roll-cage. The rear of the vehicle has a spare tire, license plate and tail-pipe while the roll-cage folds back to allow for you to place the driver in the seat. Cosmic Explorer This is a heavily modified set 70816 (Benny's Spaceship, Spaceship, SPACESHIP!) to features a new canopy from set 75176 (Resistance Transport pod) for the front windscreen, plus a rear turret that elevates and rotates in lieu of the radar dish and repair robots. To match the new canopy, the crew quarters were enlarged and opening roof remade, but the wings still fold out via the same Technic mechanism as in the original set 70816. More recently, I added a new nose to the ship inspired by DC comics set 76028. (Darkseid Invasion) The rear of the ship features the three main engines. The sensor array that was once near here was replaced by a four-barrel repeating laser turret that can rotate a full 360 degrees and elevate to 180 degrees, allowing for cover fire in almost any direction. The wings fold out if the center engine is pushed inwards, ready for the foam-tipped missiles to be engaged and aimed at any Blacktron III enemies... I did remove those yellow missiles, as they were too touchy and could fire accidentally. The main canopy has been heavily modified to allow for crew to go between the engineering and navigation sections without having to exit the ship. The Unikitty-seat area was replaced with a opening canopy for the engineering and fire-control crew to see outside from their stations near the Imagination Reactor. Deep Space Fighters These ships are deep space fighters of the Galaxy-class. Each seat one figure and have enhanced hyper-drive making it nearly as fast as LL-929. (Benny's spaceship) This ship was designed to be a heavily-armed fighter, and features an enclosed cockpit allowing for long distance travel such as from system to system if in an emergency. The rear of each of the two ship's features two engines made up of four smaller rockets. Here is the cockpit, which can seat 1 pilot figure per ship. K8-E the robot dog - Benny's best friend After meeting the Doctor (Who?) and his K-9 (pronounced Canine) unit, Benny decided he wanted a pet. So he bought himself a retired space police bot named K8-E (it's pronounced Katy) who helps Benny with his maintaining his SPACESHIP! and home base of the fleet. The two robot dogs eventually teamed up to sabotage a Blacktron and Dalek peace treaty from being signed, thus keeping the Universe safe from their plans for conquest for the moment. K8-E even took a laser shot from the Blacktron secondary leader, saving K-9 from being killed in the midst of them leaving the self-destructing Dalek ship. When reunited with Benny and the Doctor a short while later, the robot dog was fixed up and given the nod of approval from the Doctor, and a happy farewell from K-9, who left with the Doctor in the TARDIS to go to parts unknown looking for the Daleks fleeing from their loss at the hands of K8-E & K-9. From then on, K8-E has been keeping Benny company while awaiting the return of K-9 and the Doctor. K8-E is actually modified from set 8399 (K-9 Bot), which is a 2009 Space Police III set. Astro-Bot 33 - Classic Space's Giant Robot You may ask yourself: "Why would the Classic Space fleet want a giant robot?" The answer is a simple one: "Who in their right mind wouldn't want a giant freaking robot!?!?!" This model is a recolored and modified version of @hachiroku Iron Giant model, but remade it into the Classic Space color-scheme. Red and green indicator lights are placed in four spots while the feet feature hidden trans-orange tiles to signify rocket-booster output nozzles that allow for flight. I revised the robot's head, to add a central fin that is more like the 50's inspired original Iron Giant. Bumblebee stripes are also on his upper torso near the neck. The number 33 is printed just above the Classic Space logo using vintage '80's bricks as well, to give it a retro feel. NOTE: After removing the knees and fixing the ankles, the robot stands up a lot better. (I really need to take a picture of it standing up on it's own sometime...) Conveyex Crawler-Transporter This is a heavily modified Classic Space version of 2018 Star Wars set 75217 (Imperial Conveyex Transport). It's length has been doubled and the visible weapons have been removed, to make more room for passengers. Behind the trans-yellow glass of the former cargo-cars are seats, so that workers can get to Benny's space base without driving in themselves. (Call it a commuter light-railroad system, without the "rail" part!) The vehicle can be shortened or lengthened in modular sections depending on the needs of the specific mission, but in this particular case it has two crawler engine units, and two cargo hauler segments that can easily detach for maintenance or to drop more segments in / out. On each of the engine units is the dual drivers compartments, located on either side of the tread behind the square openings. Each car seat four figures, meaning the whole train hauls eight people (+ their air-tanks!). ....and yes, two of the handles on the doors are upside-down in all the pictures. Classic Space figures These are all my Classic Space figures. The thirteen green figures are the soldiers of the group, while while the six red suited people are scientists. The three blue figures are Benny (in helmet), Penelope (with pigtails), and Unikitty who are the officers of the group. The two other figures, (the red android and the robo-dog) are T-3PO, who serves as the translator to other species and computer systems, while the robo-dog is K8-E who happens to be Benny's personal pet / security guard. The astronauts you see here are the famous "Lost Six". These half-dozen brave souls were with Benny in 1988 when the space station they were on was ambushed by Blacktron I forces and blasted into a black hole. Benny managed to escape the station before it entered the gravity field, but only just in the nick of time. (He could not reach his ship mates due to a computer error with the hatch systems.) Benny's suit was damaged in the escape, and he still wears it like that to this day as a reminder of his failure to get his crew off in time. This is the last picture of the Lost Six, with Benny out of frame because he took the picture. (He was supposed to be in the picture, but he forgot to set the timer on that take.) Will we ever see these brave men and women again? Only time will tell! EDITED 12/27/18: added the 70841 astronauts (with base door) real life photo to the first post. More photo's of the base walls are coming soon! As usual, Comments, questions and complaints are always welcome!
  2. Hello everybody! I'd like to share you guys my Lego Ideas project, Servbot from Mega Man Legends https://ideas.lego.com/projects/bc40088e-611b-41dd-9231-d6a3bf3c574c This project has in total 2859 pieces with multiple features and add ons included like Customizable facepiece, Arms with customizable parts, Mega Man Helmet, Arm Cannon and a Tron Bonne Minifigure! The Servbots, (also known as Kobun in Japan), are small support robots that were created by a 14 year old air pirate named Tron Bonne to support herself in order to perform her tasks and missions. They were portrayed as neutral characters in their first debut in "Mega man Legends" back in 1997 and had their own spin-off game "The Misadventures of Tron Bonne" in 1999 with Tron Bonne as the main playable character. Not only that but they also made numerous crossovers, cameos and appearances in games like Marvel vs Capcom 2 & 3, Namco x Capcom, Dead Rising, Project X Zone and many more I personally enjoyed the building and learning experience of this project, it was a lot of fun especially learning more information about these characters as not only the Servbot's design is inspired by Lego Minifigures, but the developers of Mega Man Legends used Lego bricks to make dungeons ideas for their levels! So knowing that the developers of Mega Man Legends used Lego to inspire them, and how much I adore Tron and the Servbots, I thought it would be fun to make a Lego Ideas set out of it. I hope you guys enjoy it! Please share and support my Lego Ideas project! https://ideas.lego.com/projects/bc40088e-611b-41dd-9231-d6a3bf3c574c

  5. This is my first MOC and first time posting on Eurobricks. A few months ago, I got back into Technic by buying the Liebherr set (42100). I decided to design my own 6 degree of freedom robot. In doing research and experiments for this project, I was inspired by this post I found here on Eurobricks: I ended up making a lot of different choices in my model. Here is the big picture: I wanted to optimize for three things: It should work Maximum range of motion -- the wrist axes should be able to turn indefinitely and other axes should have as much range as is possible Built as compact as possible Here's the video with poor production values (and using a simple BuWizz profile to control it): https://www.flickr.com/photos/188456966@N07/49900167801/in/datetaken/ This was quite challenging to optimize it in this way. First of all, in order for the wrist joints to spin, they needed to be axle driven -- pneumatics won't work. In the example of the grabber at the end, I put an axle through the turntable to control the LA for the grabber. When the grabber turntable is spun, however, the grabber will open or close in an undesired way. To counter this, I used a differential and the correct gearing to compensate. Here's a picture of that: This is difficult to see in there. There is a new 2 piece differential (65413 / 65414) inside the turntable. The gears turn the differential at half the speed as the turntable which makes it so the grabber doesn't move when the turntable moves. The control for the turntable and grabber are axles on both sides that go through the next set of turntables seen here: The axle turns the perpendicular axle that goes through the turntable and is driven by another axle in the next stage. The stage has the same problem as the previous one where flexing the wrist will cause the grabber to turn and open or close. This is compensated with an additional two differentials and another set of gears. This one is particularly compact. Here's a picture of that stage: The lage gear there is a 28 tooth double bevel which is needed to get the correct gear ratio to the 28 tooth differentials. Pulling the side off of that, we see: There are three L motors (22169) here to control the grabber and first two degrees of freedom. I particularly like the gearing in the front of this section for the compensating differentials: As noted by Hanso in his series of posts, the end of this arm is actually quite heavy. I would have preferred to send all three functions though the next turntable but I could not find a solution that sturdy or compact enough. This weight caused trouble for the next turntable. To make this work, I used two turntables, one in compression and one in tension. There is a beam that goes through the center of the turntables that takes some of the load here. The next stage is a another stage that I would like to be able to turn forever so I don't want the wires to get twisted. In order to accomplish this, I also put the battery box on a turntable that turns with the rest of the arm. The wires go through this stage and don't get twisted. The humerus (in LBG) is very small (5x5) and it was a bit challenging to get the gears in there. The motors (XL 22172) for those next two axes very neatly attach there. The base has the last two degrees of freedom. The spin axis here uses a mechanism very similar to the Rough Terrain Crain (42082). The final axis uses worm gears to drive the turntables. There's a lot of force on this axis and I experimented with a variety of different gearing. The thing that worked best is displayed above. The center piece is driven and it gets geared down symmetrically to the axles that have the worm gears. Axle support was a bit tricky here: (Still waiting for the remaining black 7x11 frames to clean up the look here.) The 2nd battery box fits pretty nicely here: In conclusion, I think this works pretty well. I haven't explored the software at all yet -- just used BuWizz as a proof of concept. Many of the motors would work much better configured as servos. I wish Lego would release an SDK for Control+ so I could write an app similar to the Liebherr controls. My day job is actually a software developer so it would be pretty fun to build a full featured app to control this.
  6. Been working on a MOC, Robby the Robot from "Forbidden Planet" (1956) and a host of other movies and TV shows. This design inspired the Lost In Space robot that it's often mistaken for, but Robby is much cooler. All purist other than some cut stickers. I want to get one of the adult Belville blondie dolls after lockdown to better recreate the poster pose, rather than using the child one I had available. A bit fragile in places, but I'll think how to sturdy it up over the next little while no doubt.

    Abomirex the Mechanical Terror

    So, here's a MOC that's actually a few years old that I'd neglected to post because I wasn't super satisfied with the photos nor the build itself, but after stumbling across it again browsing through folders I think it has at least some merit, so I now present to you... The Abomirex (or A-rex if you prefer)! A mechanical monster created by one of the most diabolical minds in all the known world as a weapon of terror and conquest. Sporting massive razor-sharp claws, built-in weaponry, and tremendous mechanical strength, only the most skilled and nimble of heroes can hope to stop it. Initially conceptualized as far more overtly birdlike, with wings utilizing the clear orange sail pieces from that one Ninjago set, but I couldn't come up with a decent enough design and thus went in a more saurian direction because dinosaurs are neat. It can't see through walls, however, which could provide our hero with the upper hand. (also sort of inspired by the movie "9" and by extension the short film it was based on) Snout splits open to reveal a flamethrower. Hope your shield spell is up to snuff, or you'll be snuffed out. Get it? Fire jokes. One of its least immediately obvious weapons is its bladed claw tail, catching its opponents by surprise! But if caught, perhaps a lucky swing could bring our hero close enough to a weak point... The conspicuous power source on its back totally wasn't that weak point, why do you ask? At ease, or perhaps scanning the horizon. In profile. Torso construction detail. Full disclosure, I don't remember it being particularly sturdy, and in addition to looking somewhat jumbled overall, it's part of why I'd neglected to share it earlier. But the aesthetic still sort of works for a steampunk/dieselpunk/frankenstein mad sciencey sort of look. (also tangent time: I hate steampunk and think it's super overplayed, or at least the variation of it that everyone falls back on. what part of "british aristocracy in fancy dress with gears glued to it" is "punk", exactly?) Obligatory gag scene. Full gallery here!
  9. Navy Cannon Transformer Mech. This is a multiple transformer which can transform into multiple forms (Cannon combat car, human type robot, antitank gun and so on).
  10. LEGO Fighter jet transformer mech - similar with vf 1 valkyrie It looks like the Zeta gundam also. :)

    [EV3] GLaDOS

    This is a recreation of the robot character GLaDOS from the game 'Portal', using Technic and Mindstorms. Just to answer a question some of you may have: Why Mindstorms? Why not PF? Well for a start, I don't own that many PF motors (only got 2 medium motors and 1 XL motor), and secondly, I don't own any PF IR receivers or remotes. The mindstorms kit has its own IR sensor and remote, so I used that. Functions: 1. Head elevation controlled by EV3 large motor 2. Head rotation controlled by EV3 medium motor 3. Body elevation controlled by EV3 large motor 4. Body rotation controlled by EV3 medium motor These may not be very many functions, but they allow for most of GLaDOS's movement seen in the actual game. The range of movement is quite reasonable. Regarding aesthetics, I don't own a lot of LEGO pieces, so the model may look a bit incomplete or strange in some places. But I think I did an OK job with what I had to work with, especially the head. Some more images: Video: More info about the robot can be found here: https://www.us.lego.com/en-us/mindstorms/community/robot?projectid=d1208d08-db8f-421c-9aa7-5f618912d7b0
  12. Mini size Combiner Transformer Robot. I think if I try to build full version combiner mech (6 vehichles), it would be too big one and need to many bricks. So I built this combiner made with just 3 heavy vehicles.

    PORC-3L-AIN

    The troso is super fragile but worth it for the shape. The articulation is alright
  16. Hello every body. Few weeks ago I was about to go to bed at 2 AM when i noticed some parts left unattended on my desk. I started playing with it and 1 hour later I came up with what turned into one of the funniest and coolest little thing I ever made. :-) I like it very much, so I decide to share it with you. Let me introduce... Hector ! This is the first version of him, built only with some spare parts I had. This is why he misses a hand on this very early picture. When Lego announced their new small ball-joint system, I was very excited and ordered a handful of them off Bricklink, without knowing what to do whit it, just thinking it had some great potential. Hector is the realization of this potential. A small, yet very posable figure with a sturdy build and very lifelike proportions and articulations. I tried to give him an aristocratic and peaceful look, like some kind of tiny butler ^^ (even though he think of him a as some kind of prince). As I mentioned before, what I like the most whith Hector is his amazing posing potential ! His soles are wide enough to balance him on one feet and all the joints stay in place when posed : You may have noticed that hector seems a little different on the last picture, that's because he went trough some improvement since the V1 ! One of the biggest flaw of the prototype was the ability for the knees to bend inward. I solved the issue by adding ''kneecaps". I also made him a lighter face and made his arms and feet more sleek. I ended up liking Hector so much that I made him a friend, Pole ! But I will tell you about him later....
  17. This is the second Lego Big Dog. The object on this one is to achieve maximum running speed and stability with 4 legs. I would like to work up to a 4 leg model that can change gates from running to jumping and is steerable. The next step is steering without falling over on four legs.
  18. I tried to build a combiner robot which doesn't include 1x1 handles (26047), 1x1 clips (15712) and 1x1 brackets(36840, 36841) this time.
  19. It is a transformer robot which can turns into scorpion-shaped robot mode.
  20. I tried to build a transformer vehicle which doesn't include 1x1 handles (26047), 1x1 clips (15712) and 1x1 brackets (36840, 36841)this time. This LEGO MOC contains 19 LEGO lots and 48 total LEGO parts. Transformation stop motion animation : 00:41
  21. I find models that walk, run and jump interesting. This MOC moves forward by jumping. It gets all four legs off the ground. I call this "I need more springs bot"
  22. My new MOC is probably the weirdest Lego Technic car (I) ever uploaded- it is made to be invisible and to work autonomously. Its use case is based on the fact that at a party, you never really get the snack you want without interrupting talks of others. My solution is a small robot that follows the edge of the snack table while carrying the snack tray(s). That is where the name comes from, it 'races trays' around the table and I liked the software-origined word 'Raytracer' a lot. For the same reason why a car exists with the name 'Interceptor'. I have done some exploring in this area, a few years ago TrayRacer 1.0 was published. But it could only follow rounded tables. And that got me thinking: can you build a Lego Thing that is able to understand when there's a corner coming up? The first answer was 'no'. It was never done before and I couldn't think of any way. The second answer was 'Well, for the intended size, you will need a mechanical sensor and a mechanical 'brain' that is able to translate the 'mechanical sensor data' into 'Let's start a steering action NOW'. That's a lot of quotes, how to convert this into hard plastic bricks? After a lot of thinking, tinkering and tuning TrayRacer 2.0 was born. It is really hard when you throw the remote out of the door, to make the robot think for itself without using the convenient Mindstorms sensors. TrayRacer 2.0 uses only a single PF M motor and is full mechanic Lego Technic. There's an important reason why I only used an M-motor: power consumption. A nice robot system with a lot of sensors and actuators will be always empty as the testing is done and the party is starting. A simple rechargeable battery box with a PF M motor is small and reliable. I added PF navigation lights because it looks good in the dark, which looks good on the party. The new TrayRacer 2.0 is 4 studs high, exposing the 4-stud batterybox as a load on the back. This had to be accepted as I needed the speed control: you HAVE to be able to set the 'feeding speed' on parties otherwise people eat way too much. In other cases, maybe an old battery would have been a solution. [As a sidenote: with the new Lego Technic electronic systems coming up, I don't see battery boxes and motors becoming any smaller. This is a bad development that TLG should be aware of. ] High quality photos (Brickshelf files not yet public, so direct links:) 1 2 3 4 5 6 7 8 The video explains it all: The deep technical details- a dynamic system Usually, 'mechanical sensor data' is fed into a clutch/driving ring or a differential, which means the device using the data also influences it. The 'mechanical imput impedance' is too low (This robot is built using mostly electronic engineering concepts..). In the RayTracer 2.0, this effect is visible in the sensor wheel. It takes some effort to shift the driving ring, which means the rubber band needs to be stronger. As said in the video, the sensor wheel needs to be pressed to the RIGHT (so robot pressed LEFT) for straight driving, which is harder when the rubber band is stronger. Because the robot is very light (lithium battery, no big electric components) a stronger rubber band means it needs to push harder to the LEFT, which is only possible when its rotational inertia is higher, so then it needs to be heavier. But weight kills power consumption. A lower weight causes oscillations, as the robot slams to the left using its inertia after a succesful steering action - enabling straight driving- , then the rubber band springs back because the robot is not able to press hard enough to the left continuously- enabling the left wheel brake again-. When the rubber band is too strong, it oscillates forever, when it is just a little too strong, the robot is designed to reach a stable orientation in a few oscillations. In the video this effect is sometimes visible, you can see different dynamics with its bodywork removed! Also, as you can see, the sensor wheel is on a long lever. The lever enables tuning of the force needed to press it to the RIGHT, thus for tuning it together with the rubber band system. To summarize: because the 'mechanical information' is influenced by its 'processor', there is a fine optimum in rubber band strenght vs sensor wheel lever length vs overall robot weight. For this reason, I could give you instructions, but there's no guarantee that any reproduction would work. Any axle that is a tiny little bent, any driving ring with some small damage, even the friction of individual pins, these are all factors that influence the final tuning and need to be optimized. Instructionless building with Lego Technic is not only a unique combination of parts, it's also the way it's built and tuned that makes it a final product. Some quick photos:
  23. Yes! this my 3rd rendition of LEGO Snapdragon since the very first one made I about 15 years ago (when I first rekindled my passion with LEGO as an adult) VERSION 1 (2004) Back then most of the parts I used came from LEGO sets so I just make do with whatever colors I had. More photos here: Snap Dragon: A LEGO® creation by Yap Alan : MOCpages.com VERSION 2 (2012) Leaps and bound improvement over v1. I was pretty satisfied with the outcome then. I even cloned 2 extra copies of this creation to be displayed in a LEGO exhibition in 2015 .. so visitors can see all 3 modes More photos here: Fall of Cybertron Snapdragon Triple Changer: A LEGO® creation by Yap Alan : MOCpages.com On retrospect, I found version 2 to be pretty dated now with a few design glitch > like protruding robot head on the jet undercarriage > weak jet nosecone design that tend to detach easily > shoulders too wide (think "ROTF Leader Class Optimus Prime") > robot back kibble jutting out at a weird angle. VERSION 3 (2019) What meant to be a quick 1 week project , dragged on to about 2 weeks: My overzealousness got the better of me. Part of the long list of to-fix's: > Every nooks and corners were rebuilt to strengthen weak hinges > Rounder/more cylindrical arms. > Nosecone-kibble tucked in more neatly to the robot's back. > beast head too funny-looking. off with the buck teeth! > narrower shoulders. ..and of coz... a color scheme closer to his G1 toy version. more photos here: Alanyuppie's LEGO Transformers: LEGO Triple Changer Snapdragon version 3 Alan Yap (@alanyuppie78) • Instagram photos and videos Alanyuppie's Brick Adventures Alan Yap's LEGO Transformers
  24. This mini robot can transform into a big fighter jet. The fighter jet is half as big again as the its robot mode. It has 4 cannons on his arms and legs. The cannons' color is gray. So, that's why it's called 'Gray cannon'. in this video you can also see how I take a film for a stop motion transformation scene.
