This tutorial comes from ikalogic.com and may be become good choice for new comers. I think the electronic and the program is good enough to make the robot running smoothly… You just need to change the mechanism… use motor with gearbox like solarbotics motor GM8, GM17 etc to make easy acceleration when robot in turn left/right. DC motor with gearbox will reduce the speed, but very nice in turning position.
