INTRODUCTION
This is a most powerful standard servo motor from DFRobot so far.A
servomotor is a rotary actuator that allows precise control of angular
position.This is specifically designed for the robotics application which
requires high quality in a variety of the servo features.
The DF15RMG standard servo equips two pairs of the servo shells. One is a
stardard shell with four M4 mounting holes. And the other one includes a shell
with double bearing which is specially designed for the application of the
robot arm or the joints.The shells of this kit are thickened to make it stable
enough for motion system.
The torque of this servo is about 19kg.cm at 7.4v power supply.Using the
Arduino servo library, you could drive this servo motor easily.To reduce the
consumption of your microcontroller, this servo has a lock function for the
pulse detection. So driving it to a target position just requires one PPM
controlling signal.
