mbot 2 does not travel a route precisely. There are changes in the route after each round. Do you have to calibrate the motors or switch them synchronously?
mBot 2 does not drive precisely! How can I fix it?

@bensstar The mBot 2 sensors can only be so precise. Even if they are off my 0.001 degrees, this will still result in a lot of impression after a lot of movement.
The sensors also can’t account for friction, traction, etc., so this is just going to happen. 
You could use the color sensor and lines to have a specific route to follow, but other than that, there isn’t a lot you can do.
