Migrate Phidgets to catkin

Background

motor_control_hc listens to odom and cmd_vel messages. Configuring this feedback system is intuitive and the control does not read param values properly. The most straight forward means to debug the controller was to port it to catkin. This page documents how that was done. Other Phidgets components should be similar.

• Migrating from rosbuild
