If the robot is unresponsive after the calibration sequence and displays a Webapp error, there are a few likely causes.
The robot may have been interrupted during the calibration sequence and lost power. Power down the Glambot and recalibrate.
If operating with a large DSLR and lens, the weight of the camera may be too heavy for proper wrist calibration. Remove the camera, power down the Glambot, and recalibrate. Once calibration is complete, reattach the camera.
