The project is primarily hosted on it's website https:://schpin.org. The goal is to make affordable legged robot (~600$ price range) with enough sensory feedback for proper development of motion planning algorithms. 

It is also modular, this make it somehow easy to modify and change.

Robot uses Hiwonder LX15D servomotors and raspberry pi/stm32 for control. The software is written in C++ and uses Lua scripts to execute movements with the robot. You can see same examples here:

https://schpin.org/control/examples.html

Automatically generated documentation for the lua API is here:

https://schpin.org/control/bindings.html

Entire software stack is written using ROS, so we have full support for visualization for anything via RVIZ, etc etc etc.

The robot itself has building manual present here:

But it is still work in progress.

People interesting in joining/helping are welcome :)
