## Summary

James Bruton, the creator of XRobots and the Open Dog robotic dog, discusses the engineering and business of building complex quadruped robots. He details the Open Dog's hardware, including 12 brushless motors, O-Drive controllers, and STM32 microcontrollers, and explains his implementation of inverse kinematics using basic trigonometry. Bruton also covers his workflow as a full-time YouTuber, managing production with multiple 3D printers and CNC machines, and his transition from costume builds to niche robotics content supported by Patreon.
