Hardware

ROBOTIS U2D2

The U2D2 controller is a USB to TTL converter that allows for the control of DYNAMIXEL servos using a computer.

See the U2D2 e-Manual page for more information.

Power Hub Board

The 6 Port, 3 Pin XM/XL Power Hub allows you to split the DYNAMIXEL daisy chain into 5 separate chains while providing power to all of them. It has the additional benefit of having both a 2.1x5.5mm female barrel jack and screw terminals.

See the Trossen Robotics Power Hub Store Page for more information.

Note

Recommended Workspace is defined as 70% of total span of the arm.

Working Payload

Working Payload (g) Arm Working Payload PincherX-100 50 PincherX-150 50 ReactorX-150 100 ReactorX-200 150 WidowX-200 200 WidowX-250 250 WidowX-250 6DOF 250 ViperX-250 450 ViperX-300 750 ViperX-300 6DOF 750

Note

The working payload for each arm is the maximum weight we recommend for periods of repeated movement inside of your recommended workspace. When operating for longer periods of time, ‘rest’ poses should be incorporated to prevent servos from overheating. In all situations you should be operating at or below the working payload for your model of arm.
