Bionic hand V1.0

It’s an open-source prosthetic hand for individuals with upper limb loss.


About Bionic Hand V1

Bionic hand V1.0 is a fully 3D printed prosthetic hand for individuals with upper limb loss. It is open-sourced 3D printed with a 200×200 mm area.

The bionic hand is programed for six major grip patterns to perform everyday activities such as carrying objects, switching on lights, eating food etc.

Each finger in the bionic hand is equipped with individual linear actuators and provides precise grip patterns. The wrist of the bionic hand is equipped with quick coupling suitable for everyday use.

Bionic hand V1.0 is designed to be compatible with prosthetics research, do-it-yourself hobbyists, robot arms, and humanoid robot applications.



How does a bionic hand works


The development of anthropomorphic prosthesis getting more attention in last two decades due to technological advancements


To bridge the gap between high functionality and affordablity, state-of-the-art bionic hand 1.0 was developed.


By using 3d print technology, durable prosthetic hand with good cosmetic appearance was developed.


Bionic hand 1.0 was developed as controllable by electromyography (EMG) signals from fore arm skin of human hand.


To provide complete control over bionic hand, the open source sensors and platform of ARDUINO was used for development.


General Instructions

These general instructions tell about the parts of the bionic hand where it is used and how it is designed and what material and printer we used to design this bionic hand


All parts of hand was developed for right hand.


All parts was designed for ABS material except Logo part. Logo part was designed for Flexible 3D print filament.

Middle Finger

Bionic hand 1.0 fingers were developed with metacarpal phalange (MCP) and single distal joint combining   proximal interphalange (PIP), distal interphalange (DIP) joints as present in human hands. Finger actuation was achieved with four bar linkage mechanisam and power source of commercially available linear actuator

In this section, we assembling middle finger and attaching to palm part using 3D Print Parts and Metal Parts.


Bionichand V1


Bionic hand 1.0 thumb finger was developed with circumduction joint (CMC) as present in human hand.  The design of thumb finger was done by considering optimum position of thumb to acheive greater flexiblity and durablity with single degree of freedom. Thumb finger actuation was provided with servo control based DC motor to provide abduction and adduction of thumb finger.

In this section, we assembling motorized thumb finger with palm using 3D Print Parts and Metal Parts.


Bionichand V1


Bionic hand 1.0 wrist was developed with easy fix coupling and wrist rotation joint as present in human hand. It provides full control over wrist of bionic hand  with single degree of freedom.

As we attached all fingers to palm part, we are going to attach other parts and electronic modules to palm


Bionichand V1


Bionic hand 1.0 forearm was developed with great fitting manner and movement on users. It was developed with efficient space to power source and EMG sensors, provides complete access to end user.

As we attached all fingers to palm part, we are going to attach other parts and electronic modules to palm.

Electronic Modules

Bionic hand 1.0 was developed with open source sensors and firmware to provide complete control to end users. The developers and hobbyists can find greater flexiblity over the usge of Bionic hand 1.0.

In this section we showing the images of  connection diagrams.



What Our Client Say

It is important for the healthcare community to have an understanding of the development of bionic hands and the technology underpinning them as this area of medicine will expand.

Passive hand prostheses receive little attention in prosthetic research and literature. Yet one out of three people with a limb deficiency uses this type of prosthesis.
