 ### summit_xl_control
 
-This package contains the launch and configuration files to spawn the joint controllers with the ROS controller_manager. It allows to launch the joint controllers for the Summit XL (4 axes skid steering + 2 axes ptz), Summit XL OMNI (4 axes skid steering, 4 axes swerve drive), Summit X-WAM (4 axes skid steering, 4 axes swerve drive, 1 linear axis for scissor mechanism).
