About
BarrettHand™ is a multi-fingered programmable grasper developed by Barrett Technology, LLC in the United States. It was designed as a dexterous end effector for research and laboratory use, with three multi-jointed fingers, brushless motors, and serial/CANbus communication. Optional tactile and force sensing supported grasp research and manipulation tasks.
BarrettHand appeared as part of Barrett Technology’s broader line of robotic research hardware, alongside systems such as the WAM arm. Its role was to provide a configurable hand platform for academic and industrial robotics work, especially where repeatable grasping and programmable finger motion were needed. Publicly available historical details on its exact launch and discontinuation dates are limited, so those dates are left unspecified here.

- Connectivity
- industry-standard serial communications, high-speed CANbus, USB 2.0 (USB adapters included; Perception Palm sensors operate over a single USB 2.0 connection)
- Tactile / force sensors
- 6-axis force/torque sensor, fingertip torque sensors, and tactile sensing; optional fingertip strain-gage sensors
- Latency (glass → action)
- switches part/tool shapes electronically within half a second
Safety & Market
- Safe with humans
- Gorilla Glass is used for sensor and emitter lenses, providing impact and scratch resistance, and making it perfectly safe to manipulate objects up against the surface of the palm.
- Primary market
- industrial robotics / automation
