sendCartesianPoseAndWait

Command robot to move to desired Cartesian pose and wait for the motion to complete

Description

[result,state] = sendCartesianPoseAndWait(ur,pose) commands the Universal Robots cobot connected through ROS interface, and waits for the robot to complete the motion, based on the specified Cartesian pose of the end-effector. The function returns the goal state and the result.

example

[result,state] = sendCartesianPose(ur,pose,EndTime=endtime,TimeOut=timeout) commands the Universal Robots cobot connected through ROS interface, and waits for the robot to complete the motion, based on the specified Cartesian pose of the end-effector, maximum duration, and timeout. The method commands the robot to complete the motion from current Cartesian pose to the desired Cartesian pose within the duration and returns the goal state and the result. If the server does not return the result with in the additional timeout period that you specified, the function displays an error.

Examples

collapse all

Connect to a physical or simulated cobot at IP address 192.168.2.112 on the ROS network.

ur = universalrobot('192.168.2.112');

Command the cobot to by providing the desired Cartesian pose and by specifying the time to reach the pose as 7 seconds, and a timeout (to display an error message otherwise) as 8 seconds.

pose = [-pi/2  0  -pi/2 0.5    0    0.8];
[result,state] = sendCartesianPose(ur,pose,EndTime=7,TimeOut=8);
result = 
   1
state = 'succeeded'

Input Arguments

collapse all

Connection to physical or simulated cobot from Universal Robots, specified as a universalrobot object.

Desired Cartesian pose of the simulated cobot, represented as a 1-by-6 numeric vector, in the form of [thetaz thetay thetax x y z]. The units are radians and seconds respectively for the three axes.

Data Types: numeric

Maximum duration by which the simulated cobot must try to complete the motion to reach the desired cartesian pose, specified in seconds.

Data Types: double

Timeout period for receiving a result message, specified as a scalar in seconds. If the client does not receive a new result message in that time period, an error is displayed.

Minimum value of timeout = endtime + 2 seconds.

Data Types: double

Output Arguments

collapse all

Motion status of simulated cobot from Universal Robots, specified as a logical scalar. result is 1 if state is succeeded.

Data Types: logical

Final goal state of the simulated cobot, returned as one of the following:

  • 'pending' — Goal was received, but has not yet been accepted or rejected.

  • 'active' — Goal was accepted and is running on the server.

  • 'succeeded' — Goal executed successfully.

  • 'preempted' — An action client canceled the goal before it finished executing.

  • 'rejected' — The goal was not accepted after being in the 'pending' state. The action server typically triggers this status.

  • 'aborted' — The goal was aborted before it finished executing. The action server typically aborts a goal.

  • 'recalled' — A client canceled the goal while it was in the 'pending' state.

  • 'lost' — An internal error occurred in the action client.

Data Types: char
