Useful load up to 10 Kg

The arm is based on the servo-electric swivel units PRL combined with ERB jointed modules with integrated motor controller units, and a through-hole for cable feed-through. The combination of a high compact performance, and new materials for the connection technology allow the doubling of the payload to nominal 10 kg. The standard design of the LWA 4D is available as a 7 axes system.

The open software architecture allows for the connection and operation of any type of modules.
