Project SummaryA motorized pediatric stander is a device similar to a wheelchair, meant to assist a disabled child to move around their environment in an upright position. The device should be able to provide safe, comfortable, and smooth transportation of the passenger, with the ability to be controlled by a third party. A previous prototype used buttons to control its movement, but the start/stop was found to be very jerky and the stander did not track straight. The remote control functionality was attempted, but was not fully implemented. Safety features were not fully developed.
The goals for this project are to modify the existing prototype to include better safety features such as collision detection and a remote control for a third party. Since there are no standing patents on automated standers key constraints are cost and weight of the components we add.
Customer Requirements (Needs)and Engineering Requirements (Specifications)MSD 1 Requirements Customer Engineering and Test Plan
Primary Constraints1. Patient's range of mobility and fine control.
2. Added weight to the stander (no more than +20 lbs to current model).
3. Usage setting (currently, the stander will primarily be used in therapy/class situations where multiple objects can intrude with the ultrasonic sensors Team P13045 attempted to build an obstacle detection system).
4. Granted budget is $1,400.
5. Stander selection (Team P14045 will be working exclusively with two variant sizes of the Rabbit model stander).
