Hi every one

Im fairly new to robot building although I have been using r/c models for about 11 years and have built 2 robots one using car seat motors and one using standard servos as the drive motors.
IM thinking about building a small robot that weighs under 10kg I plan on using 4 hitec hs805 servos each with about 24 kg of torque and modifying them for continus rotation the only problem I can see is that if I have four servos 2 per channel adjusting the creep would be complicated so does any one know if making up a circuit with 4 poteiomoters 1 per servo so they could each be adjusted induviduliy will work? The robot is just for a personal challenge of making a small light robot with plenty of torque.

Any help would be appreciated many thanks mike.
