when running calibration.py of sunfounder picar-x, the front two wheel turn right and has a “crick, crick” sound and can’t adjust the direction servo, how to fix it
the similar sound like following youtube link
Just a quick note - the video you sent doesn’t have any sound.
If you’d like to calibrate the motors and servos, please run these commands:
cd ~/picar-x/example
sudo python3 1.cali_servo_motor.py
Then follow the steps in this tutorial:
Regarding your issue with adjusting the servo direction, here are a few things to check:
Is the battery connected to the robot hat?
Is the robot hat power switch turned on? (Should be in the “ON” position)
From the video, it looks like you’re powering the Raspberry Pi separately with a power bank. Important: The Raspberry Pi cannot power the robot hat. The robot hat must be powered by its battery.
Is the battery sufficiently charged?
the problem was resolved by loosing direction servo screw, and run calibration program.
Then tight the screw, the motors did not turn right, and no crick sound.
