Using servomotors – Dynamixel

In mobile robots, servomotors are widely used. These kind of actuators are used to move sensors, wheels, or robotic arms. A low-cost solution is to use RC servomotors. It provides a movement range of 180 degrees and a high torque for the existing servomotors.

The servomotor that we will explain in this section is a new type of servomotor designed and used for robotics. This is the Dynamixel servomotor.

Dynamixel is a line-up, high-performance networked actuator for robots developed by ROBOTIS, a Korean manufacturer. ROBOTIS is also the developer and manufacturer for OLLO, Bioloid, and DARwIn-OP DXL. These are used by numerous companies, universities, and hobbyists due to their versatile expansion capability, powerful ...
