WAM™ Arm/Overview
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.
Modularity
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. Internally protected channels allow the user to pass electric lines and fiber optics required for custom end-effectors and sensors.
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. In fact, an entire human-size 4-dof WAM™ arm draws only 28 watts(!) – not enough to power a light bulb –further enhancing inherent safety.
