Research platform

IH2 Azzurra.

robotic hand.

Self-contained robotic hand with all functional components (actuators, sensors and control electronics) embedded in its palm and its under-actuated fingers. Its high number of degrees of freedom and its integrated force sensors allow to carry out different types of grips and detect when an object is grasped. The hand comes with a simple communication interface (RS-232 over USB or Bluetooth). Several mechanical interfaces are available on request (for robot arms from UR, FRANKA, KUKA, as well as QDW from Ottobock).

The small size makes IH2 Azzurra the perfect research tool for clinical studies involving amputees also during daily life activities. It is the perfect tool to test and validate human-machine interfaces (either invasive or non-invasive) and control (EMG, ENG, EEG) and sensory feedback systems. Not only! Thanks to its light weight and the anthropomorphic shape, it is also suitable as collaborative end-effector for robotic arms with limited payload.
IH2 Azzurra is the perfect research platform for humanoid robotics, ergonomics, human-robot interaction, control algorithms.

open minds.

Sharing is caring. We believe in collaboration. In the ability to work with common tools.

That’s why we created IH2 Azzurra as an open research platform.

To date, IH2 Azzurra has been used in more than 30 research centres around the world for cutting-edge studies on robotics, prosthetics, human-machine interfaces, neurosciences, and more.

Catch the innovation.
