Reversed Servo for the wheels

1562991162 · Post time 2019-7-14 03:14:48

Hi,

In our PiCar-A set, I found that the wheels react at opposite directions when instructed and in auto mode as well. The camera is working correctly. How to change the code to only reverse the wheel part?

Thanks!

Ho, do You nave fix the bug? I have opposite directions in servo and in motor.

I have the same problem, would appreciate a pointer. In the directions it highlights to ensure that the motor installation is correctly orientated, but I see no markings indicating tthe motors are side specific. This issue also prevents the object tracking from working correctly so it isn't just an issue with the GUI client.

Posting what worked for me......Note that the pictures in the manual show the tops of the motors with a D shape, with the flat side against the chassis. This allows for the correct motor orientation with the correct PIN connections, but is impossible to align as there is a protrusion on that side which prevents the motor from mounting flush. Counter-intuitively, that orientation also exposes the motor wires to the wheels......

Mounting the motors with the flat of the D towards the exterior, allows flush mounting with the wires protected from the wheels, but reverses the movement directions (forward/back, right/left). These can be corrected in the move.py file by swapping the 1/0 values to the opposite values from the stock code:

left_forward = 1
left_backward = 0
right_forward = 0
right_backward= 1

Copy the Code

Please check if your circuit is correct? Is the motor reversed?

I have this problem too, and have tried to revise the "move.py file but i get an "access denied" message and can not save the file, can you help me.
thanks

Had the same with RaspTank 2 motors. It depends where manufacturer has put the negative and positive on the motor. With my motors the + and - where opposite on connector then on hat board. Either change the pins in the connector, so they correspond with board, or change the default 0 to 1, or 1 to zero in move.py.
