Straight line problem

#1

Hi all,

I recently bought the robot mbot (V 1.1 / 4 batteries 1,5V). I just wanted to move it in a straight line. Unfortunately whatever speed is chosen, it does not really move in a straight line but follows a slightly curved path. I specify that the speed of the motors has been set in the same way (100 or 255).

I tried to adjust the speed of the engines differently (M1 : 255 and M2 : 245) but that does not correct the problem.

Would you have a solution in order that my robot moves rigorously in a straight line (without using the line follower) ?

Best

Sophie

Hi Truon,

Could you upload the following program to mBot and check how it functions? Please kindly take a video to record the behaves on mBot when it run the program below:

Please note: make sure there is no wire touch the wheel on the mBot.
