Revision as of 18:28, 23 July 2019
Inspired by the Arduino Project below we'd like to create a Raspberry PI version as in https://github.com/yasaspeiris/aragog
Video
Links
- Spider robot(quad robot, quadruped)-MG90 regishu 2017
- https://www.hackster.io/yasaspeiris/raspberry-pi-powered-quadruped-bbb68b
Parts
Assembly
- Legs and hinges are connected with 1.4x5mm screws
- Legs and servos are connected with 1.7x6mm screws
We use the raspberry base from https://github.com/yasaspeiris/aragog/blob/master/3d%20printed%20parts/base.STL
