1 question about encoder


#1

What is the biggest read of gopigo encoder and how to reset the zero? And the encoder is capable of reading properly when the speed reaches 10000RPM?
Looking forward to your response.

I can answer one part of your question, about resetting the encoders:

I’m waiting on your other answers.

The GoPiGo3 encoders have 1-degree resolution (360 degrees per rotation) with a range of -1,073,741,824 to 1,073,741,823 degrees (± 2.9 million rotations).

The GPG3 motor position and speed are based on the output shaft (the wheel), not the motor before the gearbox. There is no way that a GPG3 motor will be rotating at 10000 RPM. Standard speed is more like 100-150 RPM. The encoders work fine with the full range of speeds that the GPG3 motors are capable of running.

Using easygopigo3.py you can use reset_encoders as Cleo mentioned. Using gopigo3.py you can use something like this to reset the encoders:

GPG.offset_motor_encoder(GPG.MOTOR_LEFT, GPG.get_motor_encoder(GPG.MOTOR_LEFT))
GPG.offset_motor_encoder(GPG.MOTOR_RIGHT, GPG.get_motor_encoder(GPG.MOTOR_RIGHT))
