  1. Hi all, Long time no post ;) And here's my latest powered up based mech, utilising 2 technic hubs and 8 motors. 3 motors are used for walking and turning, 1 motor is for raising the arms and moving the antenna, the rest of the motors are for arms movement. Compare to my previous bot, this bot features wider feet, allowing the mech to walk with less body tilt. I hope you will enjoy watching the video. If you have any question about it ask away :) Take care and happy building. Cheung :)
  2. Hi all, I would like to introduce you to my latest biped based on the Powered Up platform. Here's a copy and pasted quick introduction - Introducing Bot 7 - My 7th generation LEGO Powered Up humanoid biped. The bot is built with 8 Technic Large motors. Bot 7 has 6 DOF for leg movement and 2 motors for shoulder joint and arm movement. The bot has been programmed using the Powered Up app. Battery boxes have been placed on the side of the bot to improve body tilting for movement and provide stability when the bot perform a hip + knee tilt. This bot features - * Large step size continuous movement (forward, backward, left and right turn) * 360 degrees shoulder movement * 270 degrees arm movement * Incredible hip + knee tilt without touching the ground * a highly recognisable t-shirt 7 :) Comments are welcome, happy building! /cheung
  3. Hi all, Just want to share with you a RI5 creation that I have been working on for a few weeks. It is a biped robot built with 5 control+ motor and the Robot Inventor hub. The next step is to build the same bot using Control+ and hopefully by the time the build is done I will be able to program it using the new PoweredUp App. Enjoy!
  4. Hi. I'm new here but I've been lurking a bit and now I've decided to make a post. I've built a large biped, through multiple iterations in the last 7-8 years. It's a decent build but I've decided I'd like to rebuild it with linear actuators as opposed to all of the current gearing used. Just like I read another poster say in some other thread here, moving the black part of the turn table while keeping the grey part stationary will add a ton of friction. This unit works pretty good, I had it posted on the lego mindstorms site before it shutdown. I also posted it to bricklink as well. I still think it would benefit from LA's, I think there would be less friction and better overall efficiency as opposed to the current 6 turntables driven by one motor. Bricklink Destructor Page I'd like to post pictures and such here but apparently I'm limited to 102.4kb of upload on this post. Please take a look at my post at bricklink and give me some input. There is a .io to take a look at the model. I've also changed the zamor launcher I'm using since I built the digital model. I'm using a standard hailstorm configuration with standard magazines, I've found them to be much more reliable than the design I was using when I build the .io. I've considered building an "agitator" into the zamor mag to prevent ball jams, but the rebuild of the Destructor is priority. Current biped info: Walking: This is achieved by one motor mounted on the bottom center of the biped. It has an 8 tooth gear driving the turntable, which in turn drives another turn table above it and attached to it. The top turntable pulls the legs forward by about 4 studs. The turntable attached to it is responsible for driving the gear inside each leg, which changes the angle of the foot to take the weight while stepping forward. Obviously the legs are synchronized by the motor, as synchronization is very important for this model. Turning: This is achieved by driving a turn table with a worm gear attached to a NXT motor. The is a touch sensor located by a tab in the leg attached to a gear. This is synchronized with when the foot has the weight on it, allowing the sensor to indicate when the foot will be active. At the same time we also know the other foot can rotate back to its original state if it is still in a turned state. Weight: Probably around 1-1.5 kilo Speed: About 40 cm /minute Zamor launchers: Typical hailstorm style launchers. May come back to them once I can work out a way to use linear actuators for the walking portion of the biped. What I was thinking for this build: (Starting from feet up in terms of mechanical workings) First a rough motor idea, I'm using an EV3 to control the machine. Motor 1: Walking/Turning Motor 2: Gear switcher for walking/turning Motor 3: Zamor launchers Motor 4: Maybe instead of switching I could use this motor for turning?? Not sure yet.... Feet: This is where my current turning mechanism is. For a LA driven biped, I was thinking a possible gear switch mechanism to change from walking mode to turn feet mode for turning. Still deciding whether a LA or gear is the better for this. I'm kind of leaning towards gears due to the rotation forces needed for turning the foot. And the difficulty of getting rotational force through the leg down to the foot, while maintaining minimum torque/slop. Walking: I still think one motor driving both legs is best due to the absolute synchronization required. One thing I am considering Is sending two rotational forces through the leg, (if feasible) one to control walking and a gearbox to switch to feet rotation. The second rotation force will operate the gearbox for walking or turning the feet. Possibly I could use the second rotation to send through the leg, knee and down to the foot. Now that I think of it maybe CV joint could do this. Zamor launchers: Maybe they would even benefit from the LA treatment? To be looked into at a later date.... Appreciate any input anyone has. If the link doesn't work the biped is named Destructor. It's on the Bricklink Studio page. Thanks. Edit: For whatever reason the studio page takes forever to load. It eventually does though.
  5. Everyone has met Bob the Janitor at least once. Bob usually populates schools and offices, it is usually seen on its own and doesn’t form herds, and it feeds on shoeprints recovered from the floor as well as on schoolchildren’s fear. He has a strong territorial instinct and may be aggressive if his freshly cleaned floor is trespassed. Interestingly, his age appears to be constant but advanced, although all attempts at carbon dating have been unsuccessful. Theories abound about how Janitor is often actually older than the building he maintains and how he gets an extra year added to his lifespan for each scene he causes against the trespassers. The distinguishing features of a Janitor include the Broom of Doom, a sleepy yet vigilant and always suspicious look, a mandatory mustache, a cigarette that never burns out, and a belly used to store gathered shoeprints for later consumption. Thus it is possible to visually estimate the effectiveness of any Janitor by the size of his belly. The Janitor’s mating habits and methods of breeding remain unverified, mostly due to an underdeveloped sexual dimorphism (it’s extremely difficult to tell males from females), as well as due to the fact that sightings of more than a single specimen within the same territory are exceedingly rare. No one has actually seen Janitor’s offspring either, which led some to believe than instead of mating, this species relies on cloning. More:

    My own spin on the AT-DP from Star Wars rebels. This one has an artillery cannon. In artillery mode. While not as powerful as a SPHAT, the AT-DP mkII is far more mobile and can easily handle engagements with infantry or light vehicles, making it far more versitile. I wonder if how the Battle of Endor would've went if the Empire had these... The pilots. In full drive. Not a pretty sight to see for a rebel

    [MOC] AT-ST

    I've always had the ambition to make a model worthy of the iconic designs from the Star Wars saga. I don't know how I ended up building an AT-ST some months ago, but it might have something to do with my adoration of marshal banana's and Brickdoctor's masterpieces. I hope this MOC is a worthy tribute. This model is built entirely in Lego Digital Designer, and that has had its consequences. Firstly, I couldn't use illegal (or just complex) connections, which resulted in some strange decisions (I still think tiles would have been better for eyelids. For the same reason, I couldn't get a cockpit interior. The connections needed to achieve that would take a ridiculous amount of aligning pieces...). The second consequence is even more important: I couldn't test the stability of the creation. So I could have spent a lot of time thinking this or that connection would be stronger, but unfortunately I couldn't experiment. Therefor, I stopped trying to make it super stable and concentrated on different aspects. This doesn't mean I took care to avoid the connections that are obviously weak, but I can give no guarantees whatsoever the model will hold (I give it 10% max). I used that time to focus on detail and realism. I tried to follow the original model as accurately as I deemed possible, and took care to avoid studs and axle holes to give it a more realistic look. I guess this is the most studless AT-ST MOC ever made... Also, I tried to include the same amount of points of articulation as in the original model, except in the feet, that certainly wouldn't allow a freedom under such load. Finally, I didn't build this model with Bricklink's catalog next to me, giving me a lot of freedom. The result is that not all parts of this model are available though. I'm sorry that it will remain a digital model. My real objective was to make something like "the ultimate AT-ST MOC". Now I realise there is no such creation, but every creation has its flaws and its strengths. I hope you can still appreciate it. So here are the pictures [MOC] AT-ST by Bert.VR, on Flickr When I had finished the model, I couldn't resist adding a small scene very much in the spirit of marshal banana's creation. I hope you like my try at the Ewok glider. [MOC] AT-ST - from all angles by Bert.VR, on Flickr Here are some 'technical views' to give you an idea about the proportions. I really like how most shapes turned out, but in the end the 'butt' is sticking out a bit too much for my taste. Still, I think it looks great from every angle. [MOC] AT-ST - Join the Empire! by Bert.VR, on Flickr This shot ended up being way more dramatic than intended, but I really like it. It gives you a closer look at the head and shows the details I added on the underside. There aren't a whole lot of very greebly areas on the model, so most of them you can see here. There aren't really any extraordinary parts usages in there, but I tried to mimic the details as good as possible [MOC] AT-ST - glider perspective by Bert.VR, on Flickr Another limitation was that I couldn't use flexible parts. These railings could have benefited from it. The same goes for some piping on the back. But anyway, here you can see how the head comes together. I like how the seams are minimal (not an easy feat in LDD!). I'm also quite proud of the solution I found for the side cannon. You wouldn't believe how many iterations I went through to arrive at this! [MOC] AT-ST - the rear by Bert.VR, on Flickr I guess every model has that one area where the structural elements shine through, making it a bit more ugly from that perspective. This is that angle. I also had to do a lot of fishy connections to cover it all up, especially with the connections of those decorative panels. Shifting to the lower section, I'm really glad with those exhausts. I couldn't use cheese slope mosaics, but a very accidental click led me to these brancard wheel pieces, and they just snapped perfectly into place. [MOC] AT-ST - who needs stable legs? by Bert.VR, on Flickr I spent a lot of time just to get the curved section at the front of the legs. I got the shape right, but the Technic holes aren't pretty. Still, this was the best thing I could come up with. Same goes for the feet: very tricky. The original model has a nice curved shape, and the only part that can match it has to be one of the cockpit pieces. That one had impossible connection points though, so I stuck to this solution. This isn't supposed to be all complaining of course. I had a blast building this model, and I hope you see it. With my comments, I tried to give the model some more nuance for you. I'd love to hear what your comments are! __________________ LXF File available here

    [MOC] Steampunk walker

    Hello. I'm new to Eurobricks. Might as well show off my creations This is a pibed walker made for one minifig. It took me ~a day to complete, and it was a very fun build! It's harder than it looks to get the legs in it's right position at this scale to make it look good, but also to make it stand upright well enough. Please comment about what you think. Please do check my other sites as well!! (and follow me!) Instagram Flickr Reddit
  9. On YouTube, CamsPL / Cams posted of his yellow Lego Technic Walking & Turning Biped (W&TB) Mecha model. It uses three Power Functions (PF) Medium motors to walk and turn. More on his Flickr photoset, and on his Brickshelf Gallery (when moderated). He also made the red Walking & Riding Biped (W&RB). which uses four Power Functions M-motors to make it "ride, walk, skate, and turn" : ( ) (Flickr photoset) (Brickshelf Gallery when moderated)
