The function of the Joint Velocity Driver is to perform closed-loop joint velocity control. The input is the desired instantaneous desired joint velocities. The "Set Motion Profile" message is used to set maximum velocity and acceleration rates for each of the variable joint parameters. All motions utilize the motion profile data that was most recently sent. Default settings are not assumed so that upon initialization this message must be sent before the first "SET JOINT VELOCITY" message is sent. It is assumed that the manipulator begins motion immediately after receiving the "SET JOINT VELOCITY" message.
