thanks eric,
i am planning to use a pic. i am using steppers so that i get to calculate the position of the bot without any added circuitry and also to precise movements.....steppers rotate one step for a pilse but suppose the pulse are far enough ( seperation time between pulses is great) then the motor wont rotate continuosly , right? i dont want the bot to move with jerks so is there any solution to this
i am planning to use the bipolar stepper motors found in floppy drives
