Bionic hand V1.0 is 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 and can be made from any 3D printer with a 200×200 mm area.

Six major different grip patterns were programmed in bionic hand to perform everyday activities such as carrying objects, switching on lights, eating food etc.

Each fingers in bionic hand equipped with individual linear actuators and provides precise grip patterns. Wrist of bionic hand equipped with quick coupling suitable for everyday use.

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

Data Sheet

Datasheet is a document that summarizes the performance and other characteristics of a product, machine, component (e.g., an electronic component), material, subsystem (e.g., a power supply), or software in sufficient detail that allows a buyer to understand what the product is and a design engineer to understand the role of the component in the overall system. 


Build Instructions



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



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



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


Fore Arm

In this section we assembling fore arm with 3D printed parts and Metal parts


Electronic Modules

In this section we showing the images of  connection diagrams.
