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 feedback functions, position, speed, internal temperature, input voltage, and other features, and its simple daisy chain topology for simplified wiring connections.
In the following image, you can see the Dynamixel AX-12 and the USB interface. Both...
