Project Overview The previous Smart Walker prototype (Smart Walker I) has been deemed too bulky and obtrusive for use in assisted living facilities. The goal of the Smart Walker II project is to design a walker with the capabilities to collect information about the user’s health and functionalities (heart rate, temperature, etc. ) without appearing robotic or impeding the user in day-to-day tasks. The new walker prototype is designed to be mobile, semiautonomous, able to prevent and detect falls, and be capable of locating patients in its immediate environment.

Customer Requirements ● ● ● ● Reduce noise from motors while walker is in "manual mode". Systems are robust and able to withstand everyday use. Systems are concealed within the frame of the walker. Motors do not resist the manual movement of the wheels. System is capable of detecting a user's fall and executing a recovery routine. System is capable of determining presence of a user based on handle interaction. Unify software subsystems and bring them to an acceptable operational level. Software should compile necessary info into a readable file to be sent to customers. SLAM Capable. System capable of predicting pressure sores. System to brake the wheels on user input. Make the power system rechargeable and accessible to the user. Subsystems add minimal weight. System should have minimal power loss when idling. System must be readily reprogrammable.
