Description

The Brunel Hand is the second robotic hand released by Open

Bionics after the Ada Hand. Key improvements include

integrated finger friction pads, a more stable pinch grip, and a

revised custom control printed circuit board. The Chestnut

V1.0 (PCB) is based around the SAMD21G18 microcontroller

with I

C connectivity plus breakout pins. The hand is CE

marked and comes pre-assembled, so there is no need to

waste any time before getting started.

This is not a medical device.

Brunel V1.0 - Datasheet March 2017 Dedication Isambard Kingdom Brunel (1806-1859) revolutionised public transport and modern engineering. No dream was too big. Dionysium Lardner, a celebrated academic, on Brunel's plan to cross the Atlantic Ocean with a coal powered ship: "As the project of making the voyage directly from Liverpool to New York [...] they might as well talk of making the voyage from New York to the moon...
