ROS node to control GoPiGo robots (http://www.dexterindustries.com/gopigo/).
The node requires the GoPiGo driver to be installed either as catkin package or manually. The full instructions for building the GoPiGo library and ROS node as catkin packages are located at https://github.com/ros-gopigo/rosinstall-repo.
To control the robot, you need to publish geometry_msgs/Twist messages on the /cmd_vel topic. Only the linear.x and angular.z parts of the Twist message are evaluated to compute left and right motor speed.
Twist messages are published for example by the teleop_twist_joy or the teleop_twist_keyboard nodes.
