The Ultimate Guide to using Motors in Robotics (including ROS, Raspberry Pi)

Jump straight to 24:25 for the finished product! Learn everything you need about adding a motor to your robot, including how to connect it to a Raspberry Pi running ROS! Repo for Arduino firmware https://github.com/joshnewans/ros_arduino_bridge Repo for serial_motor_demo ROS package https://github.com/joshnewans/serial_motor_demo Here are a few videos explaining/demonstrating aspects of PID control (thanks to Eric Mack for the suggestions!). Hopefully some day I'll get around to making my own...
