Calibration Interface
The above screen interface will be displayed when you calibrate for the first time. You can also click to open the upper-right menu in the control panel and select "Calibrate" to re-access.
The pre-assembled robot should already have the legs properly installed but not fine-tuned.
If you are building the robot from a kit, do not install the leg components until calibration. You also need to install the battery and long-press the button on the battery to power the robot.
Enter the calibration interface, click the "Calibrate" button, and all servos will move to the calibration position immediately.
If you are building the robot from a kit, Install the servo-related components according to the second one in the Calibration Interface picture, 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). Please refer to the related chapter in the user manual for the details:
- Nybble
Use the included L-shaped tool as a reference!
Align the upper leg first
Pay attention to the reference edges for the lower leg
When calibrating, first select the index number of the joint servo from the diagram(when adjusting the leg servo, adjust the thigh first, and then adjust the calf), and then click the "+" or "-" button to fine-tune the joint to the right angle state.
If the offset is more than +/- 9 degrees, you need to remove the corresponding part of the servo and re-install it by rotating one tooth, and then press the "+" or "-" button.
For example, if you have to use -10 as the calibration value, take the limb off, rotate by one tooth then attach it back. The new calibration value should be around 4, i.e., they sum up to 14. Avoid rotating the servo shaft during this adjustment.
You can switch between Rest, Stand, and Walk to test the calibration.

Note:
You may need to do a second round of calibrations to achieve optimal results.
After calibration, remember to click the "Save" button to save the calibration offset. Otherwise, click "<" in the upper left corner to abandon the calibration.
