Overview
A tiny tethered biped from the Open Dynamic Robot Initiative, the group behind the Solo quadrupeds, built from the same open brushless actuator modules. With no ankle actuation it must constantly step to stay up, which makes it a clean testbed for dynamic balance and learned controllers. Everything, from CAD to electronics, is published.
