About this model

A light, fast, open-source research quadruped. Solo-8 has eight brushless actuators (hip and knee on each leg) with low-ratio timing-belt transmissions, so the legs are back-drivable and torque-controlled. It can jump, trot and recover from pushes, and it weighs under 2 kg. This is a refurbished remix of Solo-8 (Quadruped Robot 8dof v2) by Felix Grimminger and the Open Dynamic Robot Initiative ( Updated for modern use: the robot, leg and actuator documents brought together into one parts list, one print list with counts and one build guide in build order. What you build - 8 actuator modules: T-Motor Antigravity 4004 300KV motors with a two-stage 9:1 AT3 timing-belt reduction and optical encoders - 4 two-joint legs (hip shell, upper-leg shell, lower leg) - A printed body frame carrying the …
