Hi,

The DM and RS designations refer to the different motor manufacturers used in the arms: Damiao (DM) and Robstride (RS).

TL;DR: The RS model uses larger motors with a higher gear ratio. This means the RS version offers a higher payload capacity and greater precision, though it is heavier.

Here is a full breakdown of the differences in their capabilities:Here you have a full breakdown:

Arm Weight	4.5 kg	6.7 kg
Arm Payload	1.5 kg	2.5 kg
Arm Maximum Load	Not specified	5 kg
Repeatability	< 0.2 mm	± 0.1 mm
Max Effort (Joints 1, 2, 3)	27 N·m	36 N·m
Max Effort (Joints 4, 5, 6, Gripper)	7 N·m	14 N·m
Max Velocity (Joints 1, 2, 3)	50 rad/s	100 rad/s
Max Velocity (Joints 4, 5, 6, Gripper)	200 rad/s	100 rad/s
Joint 2 & 3 Lower Limit	-3.7 rad	-3.8 rad
Joint 6 Limits	-1.57 rad to 1.57 rad	-3.14 rad to 3.14 rad
