""" Executes a time trajectory on the robot.
This function directly executes a timed OpenRAVE trajectory on the
robot. If you have a geometric path, such as those returned by a
geometric motion planner, you should first time the path using
PostProcessPath. Alternatively, you could use the ExecutePath helper
function to time and execute the path in one function call.
If timeout = None (the default), this function does not return until
execution has finished. Termination occurs if the trajectory is
successfully executed or if a fault occurs (in this case, an exception
will be raised). If timeout is a float (including timeout = 0), this
function will return None once the timeout has ellapsed, even if the
trajectory is still being executed.
NOTE: We suggest that you either use timeout=None or defer=True. If
trajectory execution times out, there is no way to tell whether
execution was successful or not. Other values of timeout are only
supported for legacy reasons.
This function returns the trajectory that was actually executed on the
robot, including controller error. If this is not available, the input
trajectory will be returned instead.
If switch = True, this function switches to the ros_control controllers
necessary to execute traj. If unswitch = True, it also undoes this
switch after the trajectory has finished executing. If unswitch is
unspecified, it defaults to the same value as switch.
