Robotis - Dynamixel MX-28AR (Aluminium front case)

The Dynamixel MX Series servos feature a contactless (Magnetic) position encoder and PID control for superior accuracy and reliability. The MX series offers 12bit (4096) position resolution and can operate in the 360º range offering 0.008º resolution.

Dynamixel Servos are connected using a Daisy Chain mechanism and are queried and controlled with an advanced Serial protocol. Over 50 Read/Write parameters are available including Position feedback, Load feedback and PID tuning.

Compared with the standard MX-28R this newer version improoves the heat dissipation, adds threaded holes in the front for easy assembly and maintains the same dimensions so you can use the same frames as before.

Features:

Decreased noise and improved protection against heat
Front screw threads are already threaded for easy bolt assembly
Same dimensions as the existing DYNAMIXEL M-series (option frames are compatible)
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 wheel mode
Reliability and accuracy were advanced in the position control through PID control
High baud rate up to 4.5Mbps
RS-485 communication
