Problem of synchronisation motor brains astrobot Jimu cosmos

Hi!

I require your help regarding a problem I’m encountering.

problem of synchronisation of the motor brains controlling the movement of the wheels of the Astrobot robot of the ASTROBOT SERIES: KIT COSMOS JIMU.
The ID-02 motor brain starts before the ID-01 motor brain and then the ID-01 turns faster than the ID-02. The trajectory is not straight.
Have you already encountered this problem and how to solve it?

Thank you so much in advance for your help!

@Chrigo Welcome to the RobotShop Community. The issue sounds related to your code, where one motor is started first, then there might be a delay or the processor does something else, then the second motor starts. The issue of different speed might be either the code, or a normal difference in the motors where you need to adjust the speed (lowering the faster one a bit) so they are the same speed.

Hello,
Thank you for your answer.
How do I change the speed of the motors?
And, sorry but I don’t know what the code is and how to solve the problem.
Thanks for your help

That will be in the code you use to program it. Ideally the speed should be very close and the robot might move in a gentle arc. Notice the move forward command has a speed for example:
