Four-legged Servo spider with MINDSTORMS Robot Inventor

This LEGO spider has 4 legs, with two joints per leg. It walks forward, turns, and makes curves. You can remote control it with a gamepad or put it in autonomous mode. I programmed the legs with keyframe animation that I transform live. In a next version I want to use inverse kinematics and three-joint-legs.
To build it, you need:
- 1 set of 51515 LEGO Robot Inventor
- 4 geekservo 2kg (I ordered mine from China)
- 1 LMS-ESP32 board to control the servos from your hub - www.antonsmindstorms.com/prod...
- Firmware for the LMS-ESP32 - firmware.antonsmindstorms.com/
- Building instructions (or design yourself) - www.antonsmindstorms.com/prod...
- Free python code github.com/antonvh/mpy-robot-...

This unlocks many possibilities for building robots that require more than 6 motors and only 1 hub. Thanks Anton for the amazing work ❤

[@TheRealStructurer]

In my universe spiders have 8 legs, but cool anyway 😎
Thanks for sharing 👍🏼

[@karlkastor]

Very cool. I had the Mindstorms NXT and I could never have enough motors :D

[@AntonsMindstorms]

Yeah, then EV3 had 4, and now you can do 8!

[@charmingotter976rr]

thats very impressive

[@Star_cab]

Makes me think of the spider tank from ghost in the shell.

[@AntonsMindstorms]

Yes, that is an awesome tank!
