What does an RC servo do?
What does an RC servo do?
As already discussed on the RC Radio page, RC servos / actuators convert electrical commands from the receiver or flight control system, back into physical movement. A servo simply plugs into a specific receiver, gyro, or FBL controller channel and is used to move that specific part of the RC model.
What is RC in RC servo?
Servos (also RC servos) are small, cheap, mass-produced servomotors or other actuators used for radio control and small-scale robotics. Most servos are rotary actuators although other types are available.
How are RC servos controlled?
Servos are controlled by sending them a pulse of variable width. As long as the signal pulse exists on the signal line, the servo will maintain the angular position of the shaft after it has rotated to that position. As the signal pulse changes, the angular position of the shaft will change.
How is the position of a RC servo determined?
Modern RC servo position is not defined by the PWM duty cycle (i.e., ON vs OFF time) but only by the width of the pulse. (This is different from the PWM used, for example, in some DC motor speed control). Most RC servos move to the same position when they receive a 1.5 ms pulse every 6 ms…
What kind of servos are used for radio control?
Servos (also RC servos) are small, cheap, mass-produced servomotors or other actuators used for radio control and small-scale robotics. Most servos are rotary actuators although other types are available.
What kind of plug does a hobby servo use?
Servos often come with multiple attachments, such as wheels or levers, known as “horns”, than can be attached to the shaft, to fit the device they are operating. Most hobby servos use a standard type of 3-pin plug, with the same control signaling, which makes RC servos reasonably interchangeable. The connector is a female, 3-pin, 0.1″ pitch header.
Which is the best definition of servomechanism?
In the most generic sense, a “ servomechanism ” (servo for short) is a device that uses feedback to achieve the desired result. Feedback control is used in many different disciplines, including speed, position, and temperature. In the context we are discussing here, we are talking about hobby or radio-control servo motors.
