Project Updates: Prosthetic Hand

by Bryce Johnson

IMG_8061The second half of the semester was spent completing construction of the hand as well as working on the control of the hand. Currently the hand is completely built and has basic movement capabilities such as open and closing and basic thumb movement. We have started modeling the hand in CAD software in order to create a separate hand in the future with additional improvements we feel are necessary to the existing design. We have also researched possible EEG sensor configurations as well as funding opportunities for these sensors.

Next semester we plan to continue working on the control system for the hand. We would like the hand to have independent articulation with each finger. Over the course of the spring semester we propose to look at two separate user inputs for hand movement: a mimicking glove design and EEG sensors.

Project Updates: Prosthetic Hand

By: Bryce Johnson

As of now, the prosthetic hand is in a state of partial completion. All of the 3D printed parts are made and the majority of the components needed have been obtained. The fingers of the hand have been assembled and will be ready to attach to the motors once they have been tested for functionality. There are three main aspects of the project that the group is currently working on: construction of the prototype hand, EEG sensor research, and hand control systems. The group aims to have the hand built by the end of October. For the rest of the semester the plan is to add functionality to the hand by having it mimic a human hand’s motion along with continued research relating to EEG sensors and control of the hand using an EEG sensor as the input. This prosthetic hand is an exciting way for students to work on a challenging interdisciplinary project having a real world impact. New team members are always welcome. Our Facebook group, WSU Robotics Medical Device Team, announces our meeting times and has additional information about our project.
