Max num of poses to send per time: When you use the run Mech-Vision project command, you can set the maximum number of poses that can be sent by the vision system each time. The maximum number is 30.
-
Timeout for getting Mech-Viz data (s): If you use the run Mech-Viz project command and Mech-Viz does not return the result during the specified timeout period, a timeout error code will be returned.
-
Timeout for getting Mech-Vision data (s): If you use the run Mech-Vision project command and Mech-Vision does not return the result during the specified timeout period, a timeout error code will be returned.
-
Return "1102:Successfully triggered" after the capture: In eye in hand scenarios, if you select this option, the vision system will return "1102:Successfully triggered" after the camera finishes image-capturing. This way, the robot can move immediately without waiting for the Mech-Vision project to finish running, shortening the cycle time. If you do not select this option, the robot have to wait for the Mech-Vision project to stop running before moving.
After you select this option, Timeout waiting for capture completion (s) will be displayed. If the camera needs a relatively long period of time to capture the image, specify a larger timeout period. -
