You can adjust the speed of each motor as no motors are the exact same speed. The speed is adjusted on init by either editing the initialization script - or - by manual adjusting the speed sliders in the movement panel.

Enjoy!

Thanks DJ. So far I haven't had any luck as the laptop I have with me is having trouble connecting to the Rover and the mobile app won 't let me access the sliders (I'm away from home for now). The odd part is for the better part of an hour everything was fine. It also seems odd that everything is fine when I drive in reverse; no veering, it runs straight as an arrow. I'll keep trying to get in via the laptop until I get back home and can try on my desktop machine.

Thanks! John

I figured out my connection issue; anti-virus was blocking it. JUst as I starting working with the sliders, got a low battery warning, so I'll play around more tomorrow.

Thanks again John

I've adjusted the sliders for speed control and got it tracking, but to do so, I've had to drop the right speed to almost 25% which drops overall speed to slightly slower than track speed in a turn. Reverse speed doesn't seem to be affected; it positively RIPS in reverse LOL.

I have been able to do some testing on my home set up and there is definitely an issue in the left continuous rotation servo. going forward it is running approximately 75% slower than the right; so much so that when I bring the slider down on the right drive servo to get a straight path, the robot barely moves. Doing a continuous left turn (spinning in a circle), both servos are running the same speed and it does the turn rather quickly; by watching the wheels you can see they are turning the same speed. Doing a spin to the right, the left servo moves forward at a quarter of the speed of the right, which is going in reverse. This tends to suggest there is an issue with the signal being sent from the controller to the left servo for forward movement. I could verify this by swapping the connections, but don't want to do so without getting verification that this would not introduce any other control issues.

Does anyone have any suggestions?

Your not going to cause any lasting damage by swapping the connections. It's a good trouble shooting test. When done you can just swap the connections back and all will be as it was.

i had this fenomen to.see on the bottem in the middle is a cap,you can unscrew that.take the one that runs the slowest.take the rubber off and adjust the motor, by pulling it chently out and move it with one teeth fort or back. that how i did it.

here a pic

the left side goes slower,so mean to adjust the motor 1 teeth backwarts.

if not possible take right side 1 teeth forwarts.
