It looks a bit like this: http://www.getprice.com.au/images/up...572/dc1500.jpg |
I cannot overstate this enough: if you have a skid-steering robot and have not tried using one of these controllers yet, then you are putting a large handicap on the learning curve of your driver.
One of the better control approaches we've used for such a drivetrain is having the steering wheel position set a target setpoint for the rate of rotation of the drivetrain, so if you turn the wheel a given amount the robot will try to turn at X degrees/second (using gyro feedback). This has the nice advantage of eliminating rotation overshoot, since as soon as you let go of the wheel the robot tries to stop spinning by itself.
