Overview
The cheapest Raspberry Pi dog with three servos per leg, so unlike MechDog it can side-step, lean and hold body poses. The Pi (bought separately) adds camera streaming, face recognition, ball tracking and IMU self-balancing. All code and CAD files are on GitHub under a non-commercial license. Reviewers note that assembly and servo calibration take several hours, and the plain PWM servos give no position feedback.
