The SpringRC SM-S4306R Standard Continuous Rotation Servo is a great way to get your robot rolling without a motor controller. This standard sized servo has been specifically designed for continuous rotation. It comes with a JR type universal connector and is fully compatible with standard servo hardware and software. This servo standard sized servo weighs 41g and can run at up to 55 RPMs with plenty of torque to move a small robot around.
Continuous rotation servos are commonly used to build robots because they don't require any motor controller. In the old days, builders would carefully modify their servos to convert them into continuous rotation servos. These days, the servo manufactures do the work for you. This servo is compatible with the popular. Solarbotics Servo Wheels.
When using continuous rotation servos, the signal pulse determines the direction and speed instead of the angle. These servos work perfectly with the Arduino Servo library.
A set of accessories is included which contains servo horns and mounting hardware.
