Description:
The function of the End Effector Velocity State Driver is to perform closed-loop velocity control of the tool tip. The velocity state of the tool tip is defined by two length-three vectors, i.e. ?e and vtool,e. These vectors respectively represent the angular velocity of the end-effector coordinate system and the linear velocity of the tool tip as measured with respect to the manipulator base system. 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 End Effector Velocity State" message is sent. It is assumed that the manipulator begins motion immediately after receiving the "Set End Effector Velocity State" message.
