There are many essential components to develop and build a robot, such as a controller that acts as the robot’s brain, the sensor that acts as the cognition, the mechanism that is in charge of the robot’s appearance and structure, the motion group that acts as the joints, and the power group that acts as the nerves that supplies various wires and energy to the entire robot. The controller part mainly uses an embedded board, PC, smart device, and the motion part uses electric motor, pneumatic/hydraulic device, and artificial muscle. Electric motors are most commonly used as robot joints because they are cheap and easy to control.

Electric motors are used in the joints of a robot and are also referred to as actuators. It is used to drive the robot and plays a vital role to maneuver the robot. Human beings and animal can perform various movements because of the multiple joints we have. Robots can be capable of various and natural movements if they have more joints. In order for a robot to use multiple joints, the actuators must have various functions in them as well. You must be able to control it for precise movements, and also check on the motor status to prevent working beyond the actuator’s capability. Even if the robot has many actuators, it should not consume too much power and should not require the controller to have high computational power in order to control all the actuators.

Supplying robot components with various functions and performance to robot developers is the main business and core technology of ROBOTIS.

DYNAMIXEL is a robot exclusive actuator developed by ROBOTIS, and the name derived from two words.
