I've use rechargable batteries (NiMh - Nickel Hydrade - , 1,2V) with the cybermaster with no problems at all. 9V (not rechargable) in the tower. The only difference is the motors are a little slower... The NiMh I used were rated for 1400ma so even (...) (25 years ago, 23-Oct-00, to lugnet.robotics)

| | Re: single motor pneumatic pump and switch

I think the key is that the differential has a lot less resisitance than the white slip gear. Your idea would work, but if I understand you, the slip gear would be slipping the whole time the pump is pumping, meaning the motor has to overcome the (...) (25 years ago, 24-Oct-00, to lugnet.robotics)

Does this mechanism actually need the differential? If you used a 24 tooth crown (the horrible bendy one) on the motor and this turned the white slip gear for the switch and also a standard 24 tooth for the pump, the diff isn't needed, or is it just (...)
