P16041: Smart Walker IV

Project Summary

The Smart Walker is a device that furthers the assistance that can be given to the elderly in long term care facilities. The device will have the same look and feel as a standard walker, but is able to perform many other diagnostic functions. It will collect life signs such as heart rate and temperature, as well as using sensors such as microphone array, infrared camera, and accelerometers to determine when a patient falls or is at risk of falling. The walker will also be able to navigate in the room autonomously when it is not in use by the person. Thus, locomotion and obstacle avoidance hardware and software are required.

The main goal of this year’s senior design project is to complete the integration of all subsystems on the Smart Walker and test the robustness of the mechanical components as well as the completed system. All software will be tested and validated in order to verify correct and safe system operation.

Project Background

Over the last three years, three senior design teams have worked on the Smart Walker project. Smart Walker II pulled together an initial prototype encompassing most of the system requirements. Based on the results from SWII, Smart Walker III was built with improved sensor and clutch functionality as well as providing a more refined design. Smart Walker IV is the final iteration of this project and will integrate the functionality and objectives of all previous teams, in order to create a fully operational Smart Walker.
