  1. Hey everyone, I'm really really excited to share this one with you. It's a Lego Technic swerve drive! This is the first time I've truly combined both software and Lego. The swerve drive sports 2 EV3s equipped with EV3Python V2, along with 8 motors. 1 EV3 controls steering and the other controls driving. Both are sent instructions from my computer (or yours because the code is public) which runs a custom python SSH. The swerve drive can be controlled by a joystick (which is written in with the SSH) or it can run autonomously and detect objects (the 2 EV3s communicate through my computer (another SSH) and send each other instructions). The swerve drive is built with 4 identical modules connected together. It is super robust and runs at a 1:1 gear ratio, but there are 2 places (for each module) where the gear ratio can be changed. If there's one drawback, I'd have to say it's that this thing eats battery like crazy. Each EV3 has 6 batteries, and since they each power 4 motors, battery drops very quickly to unusable rates. This is most likely caused by the weight of the model but other optimisations could be made too. OK, I'll stop talking. There's a document with further explanation here. Here's the video! (The code is in the description of the video) Pictures: That's all from me. This project was a blast, so expect more (like lots more) EV3 soon. Thanks for reading! C&C welcome.
