Prosthetic Hand: Structure, Riley Smith, Riley Smith

All Undergraduate Projects

The objective of this project was to design the structure of a prosthetic hand that has articulating fingers and thumb in order to grip various objects. A design was developed that can add to the available options of prosthetics on the market.

In order to create a base hand for the project, the hand was modeled off of rough human hand dimensions. Analyses determined the feasible size of components. Once a base size was found the movement system in both grip and return form were developed and refined. With the parts being modeled in Solidworks and 3D printed, iterations of …

The Team was tasked by NorthStar Casteel to create a device that would allow for easy mobility and manipulation of unfinished cast products. The device is needed to increase manufacturing time and decrease worker strain. In order to do this the team designed a custom gripper to match the castings produced at this facility. The gripper was powered by a pneumatic system due to the speed and reliability in this …
