PrairieDog is a robotic platform we are building in the course Multi-Robot Systems (CS4380-7000). It is built on the iRobot Create platform and uses the ROS operating system by Willow Garage and OpenRave developed by Rosen Diankov. The PrairieDog is the 4th design iteration of an educational robotic platform developed within the Distributed Robot Garden project at MIT. In version 4, the robot is equipped with a more capable arm with position feedback, a laser scanner, and a netbook.
