The joint calibration interface for Nybble in the Petoi Desktop App is as follows:
After entering the calibration state, , with all servos rotated to their zero angles, attach the head, tail, and legs prepared in the previous section to the body. They are generally perpendicular to their linked body frames. The calibration pose is shown below:
Install the servo-related components according to the picture above and try to ensure that they are perpendicular to each other (the upper leg is perpendicular to the torso, and the lower leg is perpendicular to the upper leg).
Use the included L-shaped tool as a reference during calibration. According to the index numbers of the joints shown at the top of the interface (when calibrating the servos, adjust the upper leg first, then adjust the lower leg). Drag the corresponding slider (below the index number), or click the blank part of the slider track to fine-tune the joint to right angles.
