Team Vision for Problem Definition Phase

During the Problem Definition Phase, we planned to:

By the end of this phase our team accomplished these goals and uploaded all deliverables on EDGE.

Project Summary

A device developed to mitigate Essential Tremors was created without an effective way to test the device. The device was designed to stabilize the arm during tremors but there is no sophisticated way to measure any of the forces of the device to determine if it’s effective or not. A test rig needs to be developed to test the tremor mitigation device and to provide feedback on its performance.

The goal of this project is to develop a way to test the tremor mitigation device. The test rig must mimic a human arm and be able to measure the performance of the tremor mitigation device. The test rig is limited by a budget of $500, dimensions of 3x2x2 ft, the physiological data collected by the DAQ team, and the real range of motion of the human arm.

Outputs and Destination

The engineering requirements that affect the most customer requirements are the requirements for the accuracy of the motions. In order to properly test the mitigation device, then it is of the utmost importance that the device is accurate to the motion, and this is the requirement that the group is also most concerned about.
