Calibrating two robots

In robot-robot calibration it is assumed that robot R1 is already in the correct location, and thus R1 is used ar a reference to calibrate R2. First upload both robot-robot measurement to both robots respectively. Touch-up the points by selecting the Touch-up tool from calibration help tools. Select the scope for current sequence and the tool to the one that has the short spike data and click ChangeTool.

Then copy the uploaded sequence from R2 to R1:

Click robot R1 active

Select Calibration Tools -> CopyCalibSequence

Select robot R2 and the correct sequence

Then click on robot R1 and select Calibration Tools -> LSQ. First select the component to be calibrated:

Robot R2, if it's not attached to anything

Pedestal if robot R2 is attached to a pedestal

Track if robot R2 is attached to a track

Gantry if robot R2 is attached to a gantry

Measured sequence is the robot R1 sequence and reference sequence is the copied robot R2 sequence.
After hitting Calibrate, the position of the component is automatically changed and the LSQ error can be seen from the output panel. The calibration result can be reset by hitting Reset.
