Servo Motor Buyers Guide
Self-Contained Electric Devices that Rotate or Push
Servo motors can be used in many ways from helping your robots walk to moving remote-controlled boats or cars. Servos range in size from miniature for small projects to larger sizes for industrial purposes.
Servos are constructed from these basic parts; a motor and a potentiometer that are connected to the output shaft and a control board. The output shaft can be positioned to specific angular positions by sending the servo a coded signal. Servos are used in radio controlled airplanes to position control surfaces like the elevators and rudders. The motors are small, have built in control circuitry and have good power for their size.
Continuous Rotation Servo Motors
These are servo motors that have been built specifically for continuous rotation, making it an easy way to get your robot moving. They feature two ball bearings on the output shaft for reduced friction and easy access to the rest-point adjustment potentiometer.Specific Applications:
- Building a miniature walking robot
- Creating grippers or other mechanisms for small robots
- Moving control surfaces on small model aircraft
