This thesis demonstrates a new design for an upper limb prosthetic wrist that gives 3 independent degrees of freedom (DOFs) through individual mechanisms. A human wrist has 3 degrees of freedom i.e. Flexion-Extension, Radial- Ulnar deviation and Pronation-Supination. The upper limb prostheses that are currently available in the market generally provide 1 (usually Pronation- Supination) or at most 2 degrees of freedom, which is not su cient for daily life. For this thesis, a new wrist having all the 3 DOFs was designed in the SolidWorks software, a prototype was 3D printed and a basic analysis of the mechanical properties of the model through SolidWorks simulation was carried out. The prototype mechanisms were then connected to servo motors, with potentiometers as their inputs, that were programmed through an arduino and were tested to see if they work as expected. Faithful recreation of the wrist motions was achieved and the range of motion (ROM) of this prosthesis was similar to the ROM of an actual human wrist. This thesis also looks at the other prostheses that are available in the market or are under development and their limitations are discussed. The goal of this thesis is to present a design of an upper limb prosthesis which addresses some of the limitations while also encouraging further research and development in this eld and will hopefully result in more people with amputations choosing to use prosthetics in their daily lives.
