Is an RCX robot sensitive to voltage?
The power of the Robot is dependent on the voltage of the batteries. This is not always the case with electric motors, frequently it is the power, not the voltage, that matters. But with the RCX higher voltages will produce more power at the motors. At 9V (alkaline batteries) the motors have 40~60% more power than at 7V (NiCd or NiMH rechargeables).
