SunFounder PiDog Kit, Release 1.0

2.2 Funny Project

2.2.1 Calibrate the PiDog

Due to possible deviations during PiDog installation or limitations of the servos themselves, some servo angles may
be slightly tilted, so you can calibrate them.

Of course you can skip this chapter if you think the assembly is perfect and doesn’t require calibration.

The specific steps are as follows:

1. Put the PiDog on the base.

2. Run the

0_calibration.py

home

pidog

examples

sudo python3

_calibration

After running the above code, you will see the following interface displayed in the terminal.
