We use slow motions and degrees for turning. when possible we prefer to turn in place then move.

Since you are trying different speed and if you like to experiment then try using a differential gear for better rotation and consistency. The Hightechkids website has a simple exercise on this option. Try it out first before you perform surgery on your robot unless you have spare to test it out.

Detail explanation on differential is listed in section 2.5 of the following reference.

BTW, above text also has Wheel and tire sizes in mm on page 3.37 which can be found on the wheels.

Subject: [VADCFLL-L] Tips and tricks for consitency in turning

Thanks for all those who shared their ideas on gears.
 
Can anyone suggest tips and tricks for getting consistency in turning the robot.
 
We have slowed down on turns. It has improved but still lot of error.
 
Thanks in advance.
