The WAM® Arm
The WAM® Arm is a highly dexterous, naturally backdrivable manipulator. The only arm sold in the world with direct-drive capability supported by Transparent Dynamics™ between the motors and joints, so its control of contact forces is robust—independent of mechanical force or torque sensors. It is built to outperform conventional robots with unmatched human-like grace and dexterity.
The WAM® Arm is available in two main configurations, 4-degree-of-freedom and 7-degree-of-freedom, both with human-like kinematics. The joint ranges exceed those for conventional robotic arms.
Higher Performance than Conventional Manipulators
Matching advanced electronics with inherently backdrivable cable drives results in superbly graceful motions. Barrett owns the technology for the highest performance servo-electronics available in the world today. These electronics are also the smallest (43 grams) and most power-efficient servo-drive electronics available today.
