  1. [MOC] Lego Technic Cactus Crawler

    Nope, I'm not doing body work as it would, in one way or another, detract from its performance.

    Yup, definitely for this crawler. I've even tried working it into the steering for larger crawler projects but its size makes it very difficult.

    Thanks! It was in Brooklyn, near the bridge. There are a lot of great areas to film there, especially recently since they have now renovated, adding lots of great rocks for crawling as shown in the video. This is actually where I filmed most of my shots for my Unimog Trial Truck. I, too, like my steering solution. It provides a great turning radius, rigidity, and a decent speed. The only downfall, however, is that the plastic linear actuators cannot handle too much torque and, thus, slip quite often. There is absolutely nothing I can do about this, however, with the only solution being lego designing a more heavy-duty LA of the same size. Thank you, that is what I am aiming for!
  4. Hey Everyone! Here is the successor to my Lego Technic Chili Crawler, the Cactus Crawler It took about half of a year of design and revision to reach its current state, of which I am proud of. THE VIDEO: youtube Features: - 3 L-Motors for drive (two in the rear axle, one in the front) - M-Motor and a small linear actuator for front steering - Rigid, triangulated 4-link suspension for the front axle, with large, soft, black shock absorbers - Extremely rigid 2-link rear suspension with ball-joint pivot point on top of the axle, similar to that found in the RC "Mantis" crawler - 100% Lego-legal custom curved rear links that, with how the main cab is shaped, provide exceptional ground clearance towards the rear of the crawler, allowing it to climb up relatively large vertical structures such as street curbs - Very minimal, light bodywork - BuWizz for extra power and SBrick for a great, custom control scheme Note: By the time I finished designing the cab and it's battery enclosure, BuWuzz had not yet come out with the update for their iOS app that allows a single joystick/slider to control multiple outputs, so I was forced to use an SBrick with the BuWizz, providing the extra power from the BuWizz, but with the ease-of-use and great custom control profiles of the SBrick. When used with the SBrick, the BuWizz does in fact still provide more power than the standard Lego 8878 LiPo battery box. - RC4WD 1.9" Krypton scale tires - Two green pieces so that I can call it the Cactus Crawler ;) LXF hopefully coming soon, the tires can easily be found with a quick google search of their name. YES, I know, there is no body. This is meant for performance, meaning I made the cab as small, light, and rigid as possible. I will be able to reply intermittently throughout the day. I figured I'd put this up now anyway! pt

    Sounds great, I'd like to see the photos and video. I was considering using a Servo motor as it would have required less gearing and therefore theoretically should have been more efficient (less backlash/friction) than the current solution. As you mentioned, though, because the Lego servos are weak relative to those used in actual RC crawlers, we must decide between having high torque and small steering angle or vice versa. Another issue I have found with the servos is that they require constant power to hold their position; at least when they are not in their default position. This means that the servo is taking power away from the drive motors, whereas my solution requires no power to stay in any position, allowing full power to the motors. Until Lego releases a more powerful servo/battery solution, I likely won't use any servos in my larger creations. That being said, I have not yet tried using a servo setup with the BuWizz. The extra voltage and temperature limit will make it less of a strain on the vehicle's other functions. The M motors are an interesting idea. pt

    Wow, I just read your article and watched the video. Firstly, I think the crawler looks really cool in blue, it's like my Chilli Crawler's inverse, a Chilly Crawler. Thanks for letting me know that you made it, it makes me glad to entertain people by doing what I love. And your BTBox... Well that is simply on another level! That is incredible that you just decided to, instead of buying an SBrick or BuWizz, make your own! That's beyond impressive. I'd be interested in seeing if you plan to do anything else with BTBox; perhaps a BTBox 2.0 sometime soon . Thanks again. pt P.s. Oh, and by the way PlastiBots and everyone else, I will release a video for my new, better crawler hopefully by mid-September, maybe sooner.
  7. Lego E-formula competition idea

    Well, granted, this entire competition is online, which inherently limits our ability to judge correctly. It would require MUCH more planning, organization, work and therefore time to do this competition if we were being exact to the point where we thought that everything was "fair" and "standardized." Keep in mind that these are Lego cars that are not even using buggy motors or BuWizzes or anything, so it is nearly impossible to make a Lego car that has enough speed or simply overall performance that it would need to be controlled as if it were a real RC. And, even if we decided to be this exact and use some sort of complex track design that everyone had to assemble, how do we fairly judge? Yes, watch the video. But who is to say someone will not simply do multiple takes of the car doing each part of the track and stitching together only the best takes. That certainly won't be fair and there will be almost no way of controlling for it. Thus, I think we need to relax on the track restrictions as we can only be so thorough in an internet-based competition. LXF, I am not targeting you in any way. I am simply using your points as a springboard for mine.
  8. Lego E-formula competition idea

    Yes, great. Hopefully ZBLJ will be on board.
  9. Lego E-formula competition idea

    Hey, I like this So I'll probably jump into this competition as well. It all looks great and I like the vehicle requirements. Something that I am not sure about, however, is the track requirements. They are way too specific and seem as if we have to do way too much work for the track itself. We should focus on the vehicles. Speaking for those who live in densely populated city areas, making and utilizing a track of this size and complexity is no easy feat. I am going to go ahead and assume at least a few people here saw the online truck trial competition video that me, White Shapes, Samorak and a few others had a while back: here The requirements for the vehicles themselves were about equally as specific as the ones we have for this comp, but there was essentially no limit to the track. This made it much easier to plan and film and also provided leeway for us to be somewhat experimental and showcase specific traits of our vehicles. I feel that that competition was planned and executed very well (credit to Samorak’s Technic Vehicles) and turned out to be a lot of fun. If we put too many rules on this comp, including forcing people to buy materials and assemble an entire track layout, this comp will be less about creativity and innovation and more about work and skirting the rules. All I am saying is that the track requirements are too specific. We can certainly ask in the requirements of the comp for like a clip of it doing a 90 degree left turn and another of it going full throttle on a 3 ft straightaway; in fact, I think this is a great idea. But having us literally make a large track is unnecessarily laborious as well as quite impossible in some of the places that people here live. Sorry for shaking things up.

    OMG! It drifts so well! And it doesn't even turn on the voltage protection.
  11. [MOC] 2WD Drift Racer Chassis

    Despite - or rather because of – its simplicity, I may actually have to build this. And yes, a BuWizz on this would be nuts!
  12. [MOC] Lego Technic Chilli Crawler

    Wow. This certainly came as a surprise, but a welcome one. Thanks for your kind words nerdsforprez and I am intrigued by your idea about the 5l liftarm. So, by removing it, it leaves the 14t gear connected directly to the motor unbraced on one side, right? And if so, have you had any issues with it coming out on its own or grinding at all? Your color scheme looks stellar and your rim/tire combination gives it a closer resemblance to competition RC crawlers. The BuWizz appears to be an improvement over the SBrick and 8878 battery box combo, I may have to invest in one. Thank you for giving credit where it was due. And jeez, those camera angles and setting in the video P.S. I am currently working on another crawler of a slightly smaller size with performance that rivals that of my Chilli Crawler. Hopefully, the video will be out sometime over the summer.
  13. [MOC] Lego Technic Chilli Crawler

    Um, haha, well, uh, no. I did not set any sort of limit to prevent oversteer. I rely upon my primal instinct to guess when I should stop turning. Sorry! Besides that, however, I am very impressed by your build. That body makes a great addition!
  14. [MOC] Lego Technic Chilli Crawler

    Haha thanks, and I now realize that I could have just looked at where it said UK, oh well!
  15. [MOC] Lego Technic Chilli Crawler

    Thanks, Not to be weird, but do you happen to live in Germany? as youtube told me when posting it that it would not be available in Germany due to copyright issues. Sorry for the issues with the video, hopefully it will be resolved and become available later.
