Human Inspired, designed with Dexterity in mind

The RH8D features 19 degrees of freedom, including opposable thumb and a full spherical wrist joint.

Additionally, 3-segment fingers are controlled by smart actuators.

The RH8D is inspired in the Human hand to be capable of performing the most important grips.

Advanced Mechanical design

19 Degrees of Freedom
8 Smart actuators for precise control
(actuators contained inside the unit)

Under actuated design aims to provide the right balance between fine control and conformance to the shape of the objects.

Sensorial feedback

All actuators provide real time control and feedback of position, speed and current measurement (with direction), enabling inference of applied force.

Additional data including actuator temperature, (over)load status and PWM, a Palm ToF Distance sensor and optional Capacitive pads at the back of the palm complete the sensor array.

FTS Tactile Pressure sensors (shown in the image) are optionally available when high resolution force sensing is required (1mN / 0.1g resolution).
Available in 3 axis (FTS-3 measuring contact force and shear forces) and 1 axis (FTS-1 measuring contact force) variants

iRHEcoSense – Intelligent Robotic Hand
Description:
The iRHEcoSense project focuses on the development and validation of an advanced robotic hand with distributed sensing and artificial intelligence capabilities. The project aims to enable precise, adaptive, and intelligent object manipulation, improving efficiency, reliability, and sustainability in industrial, scientific, and medical applications.

This operation is funded by the Portuguese Recovery and Resilience Plan (PRR) and by the European Union – NextGenerationEU, supporting innovation, digital transformation, and the green transition.
