What does RC stand for?
RC has two common meanings in robotics. The first is an abbreviation for radio control, signifying that a component is compatible with typical radio control systems. For the robotic hobbyist, this means that a component such as a motor driver or servo uses the same PWM signals that are used by a typical radio control receiver. This PWM signal is usually around 50 Hz, with a pulse width (high time) of 0.5 to 2.5 ms. The width of the pulse can control a motor driver or a servo, for example. The second is shorthand for resistor-capacitor, which is used in filtering applications and to model many types of loads.
