Hello ROS Fans, I would like to announce a new stack for controlling an Arduino-based robot with ROS. The documentation can be found at: http://www.ros.org/wiki/ros_arduino_bridge The stack includes a base controller for a differential drive robot as well as support for reading sensors and controlling PWM servos. The code does *not* depend on rosserial. The packages have been tested against the ROS navigation stack (Electric) using a Pololu motor controller and Robogaia encoder shield . This stack comes out of a discussion amongst members of the Home Brew Robotics Club (HBRC) for extending ROS support to hobby-level robots using inexpensive and easily obtained hardware. The code was inspired by Michael Ferguson's ArbotiX drivers and borrows heavily from it. (Thanks Fergs!) --patrick http://www.pirobot.org & http://hbrobotics.org
