MARS's arm uses 3 types of dynamixel actuators:

1	Dynamixel XL430	Robotis	XL430-W250-T	2	Product Page
2	Dynamixel XC430	Robotis	XC430-T240BB-T	1	Product Page
3	Dynamixel XL330	Robotis	XL330-M288	4	Product Page

These were picked for their robustness and repeatability over alternatives. This arm can for example repeatably play chess (see MARS Example use-cases).
