The Brunel Hand 2.0 is an advanced, lightweight and precise robotic hand for researchers. With a low cost and open source design, this fully articulated device is primed to revolutionise the future of robotics research.

All over the world, university researchers and roboticists are using the Brunel Hand 2.0. It has nine degrees of freedom, four degrees of articulation, and can be programmed using the Arduino programming environment.

The Brunel Hand 2.0 is compatible with robot arms and perfect for anyone doing a project with robotic hands or wants a neat, light, and functional robotic hand for use with a humanoid robot. It's an excellent platform for research into prosthetics, object grasping and many human-robot-interaction applications.

3D Printed Components:

All of the components required for a right hand start with 'RH' and the components for a left hand start with 'LH'. Assembly instructions are available!

3D Printed Parts:

PLA Filament parts - Ultimaker | Nozzle Diameter 0.4mm | Resolution: 0.1mm

Cheetah Filament - BQ Witbox | Nozzle Diameter 0.4mm | Resolution: 0.25mm

Please Note: Most parts require support, please ensure no support is added within the tendon channels, this is NOT required and very difficult to remove.

The majority of parts are printed with PLA with exception to the following, which are printed in Cheetah Filament:

Finger Ligament
Thumb Ligament
Cable Tidy
Stand Grip Band
Urethane Finger Grips:

The urethane finger grips are cast onto the fingers using our in house moulds, these moulds will be made open source soon!
