[QUOTE="Peter, post: 2261, member: 548"] Yes, that is critical for cows accessing multiple robots. The cameras need to be calibrate to almost identical numbers. Needs to be done with the camera calibration board. Just had that experince with a left and right hand machine. One camera was tipped to the side by one degree. The other was tipped one degree the opposite way. So it doubles the amount the arm was out to the side when a cow went from one bot to the other. I used a small level (angle degree measuring) to set them to level across (side to side of the cow) Then the 6 degree angle, plus measured the distance from the robot frame to side of camera, got those equal. Then recalibated both cameras with the calibration board and the numbers came up very close. Virtually no failures now. Get your service tech to do this and it will greatly improve attachment. Also the entrance gate has to be closed and the floor clean to take the background image. Watch for dirt on the camera face. I was amazed how a single strand of spider web hanging in front casued the arm to jerk around. Keep you software up to date. Been major improvements. [/QUOTE]
