ROS node to control GoPiGo robots (http://www.dexterindustries.com/gopigo/).
The node subscribes to /cmd_vel (geometry_msgs/Twist messages) and evaluates linear.x and angular.z to compute speed values for the left and right motor.
To build, you also need to install the library ros-lib-gopigo that provides the functions to communicate with the GoPiGo firmware.
To run, publish Twist messages e.g. by the teleop_twist_joy or the teleop_twist_keyboard nodes and run the ropigo_node.
