As a group, we all have an interest in robotics and prosthesis. We all agree that there exists a gap in the spectrum of upper limb prosthesis between cost effectiveness and functionality. Our skills compliment each other, and we truly think there is a better solution to a functional, cost effective prosthesis.

Our overall goal for Krobohand is to create an exceptionally functional and cost effective prosthesis, effectively bridging the gap in functionality and cost that exists in the prosthesis industry. The following objectives support this goal:

1.) Innovative fabrication with a FFF/FDM Printer using dual material 3D printing with co-polyester and thermoplastic elastomer filaments.

2.) Streamline process of connection between prosthesis and amputee using electromyography, or a hybrid of manual and electromyography.

3.) Design of prosthesis is sleek, clean, and recognizable.

We think that our use of dual material 3D printing in the field of prosthesis on FFF/FDM 3D printers – essentially, the cost effective 3D Printers, is essential. Certain innovations we’re working on, such as the integrated extensor tendon within the body of the finger, will create a prosthesis that is more closely resembling that of a human hand.

Further, we’re working on creating each finger to be modular, so that it can be changed out easily if ever broken, as well as the ability for the finger to move laterally – something that current prosthesis rarely have the functionality to perform. This will continue to have the prosthesis resemble the functionality of the human hand.

Ultimately, this project is leading to a start up company that we as a group are working on founding. We hope that through this project, we can continue to develop our idea, bring it to fruition, and bring it to market for amputees in need of a cost effective, but functional prosthetic hand.

We also plan on running a Kickstarter campaign as a way to earn initial capital for the start up, once we have a fully functional prototype.
