What it can do

Written by Robotheca from the project's documents.

  • Walks dynamically on two legs
  • Uses imitation learning, full-body MPC and WBC for gait planning
  • Controlled by upper computer via STM32 control board
  • Adjusts joint limits in URDF for electrical control limits

Works with AI

Found by Robotheca in the project's files at commit 7e95627, its robot.yaml and Robotheca's notes on its documents. Never guessed; Robotheca doesn't run the code.
