Robotis - Dynamixel MX-28T (TTL)

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 like precise control, PID control, 360 degree of position control and high speed communication.

Characteristics:

• Advanced durability, degree of precision, and wider control zone were achieved thanks to newly applied CONTACTLESS ABSOLUTE ENCODER
• 360º POSITION CONTROL without dead zone
• 4096 PRECISE RESOLUTION by 0.088º
• SPEED CONTROL at ENDLESS TURN MODE
• Reliability and accuracy were advanced in the position control through PID CONTROL
• High baud rate up to 3Mbps
• TTL LEVEL COMMUNICATION
