FloydTheRobot’s Dual Arm Controller

Madgrizzle’s FloydTheRobot is an ongoing DIY ‘bot project with ever-evolving capabilities, the latest being the addition of two quite versatile-looking Teensy 4.1-powered arms.

The controller has four TI DRV8874 H-bridge motor drivers and four ports for Hiwonder HX-35HM Serial Bus Servos. Two PWM servos control pan/tilt of the robot’s camera, and integrated fan management keeps the servos cool.

See it all in action in the video below, driven by the ROS MoveIt motion planning framework.
