Servomotor Dynamixel MX-28AR

Servomotor Dynamixel MX-28AR by Robotis

DYNAMIXEL is a robot exclusive smart actuator with fully integrated DC Motor + Reduction Gearhead + Controller + Driver + Network in one DC servo module. MX-series is a new concept of DYNAMIXEL with advanced functions, such as precise control, PID control, 360 degree of position control, and high speed communication.

For full details of the Robotis servomotor Dynamixel MX-28AR, consult its dedicated sheet on the official website HERE (Protocol 1.0) or HERE (Protocol 2.0).

• Advanced durability, degree of precision, and wider control zone were achieved thanks to the newly applied CONTACTLESS ABSOLUTE ENCODER
• 360 degrees POSITION CONTROL without dead zone
• 4,096 PRECISE RESOLUTION by 0.088 degrees
• SPEED CONTROL at ENDLESS TURN MODE
• Reliability and accuracy were advanced in the position control through PID CONTROL
• High baud rate up to 4.5Mbps

Caution : The set of 6 servomotors ensures a unit price lower than the purchase of a single model but does not include the accessories normally provided.
