Robotic Hand and Arm

Prenislia Robotic Hand and Arm

Prensilia designs, customizes and manufactures advanced anthropomorphic under-actuated robotic hands endowed with embedded actuation, sensory and control systems, that can be exploited in research as advanced hand prostheses, end-effectors for humanoid robots, for rehabilitation and/or neuroscientific experiments; in general, in all research fields where it is important to have an artificial hand that behaves as a natural one.

IH2 Robotic Hands (Self-contained)

Intrinsic robotic hands with all functional components (up to 5 motors, up to 10 force/tension sensors and the controller) integrated in the palm and in the underactuated, self-adaptive fingers. Light weight: 640 grams! Able to grasp and sense objects. Simple communication interface (RS232). Standard prosthetic wrist attachments available.

Key Features

Light weight: 640 grams!

Compliant grasps

Thumb ab/adduction


open-platforms for research. Five compliant fingers are independently driven by electrical motors, by means of tendon transmission. The thumb ab/adduction actuator is placed within the palm, whereas the fingers flexion/extension motors may be hosted either into a mechanical platform (for portable systems, see picture on the left - standard setup) or onto specific braces to be secured around robot arms (see picture below), based on customer needs. Current sensors and position sensors are available for bi-directionally interfacing the hand with the robot. Motorized wrist and other degrees of freedom available on request. These hands, host an embedded controller and operate through a simple communication interface (RS232).

Applications Research in: rehabilitation, humanoid robotics, assistive

The compact size of these hands allows using them in research, evaluation and clinical experience with humans in real daily living environment on Neural-Machine interfaces (either invasive or non-invasive) and control (EMG, ENG, EEG, sensory feedback systems, etc). Not
