Abstract
The primary objective of this project was to design and fabricate the electronic, power, and control systems for a mobility device oriented around the needs of a young man with cerebral palsy, named Lane Bryant. This project was completed during the Mechanical Engineering Capstone Senior Design Experience. A separate group completed the design and fabrication of the wheelchair’s ergonomic and structural elements. Research on the typical operation of existing electric wheelchairs was completed to form a baseline of operating parameters. Observations from a previous wheelchair for Lane, called the Wild Thing, guided many design choices. The power supply was designed to be as lightweight and reliable as possible with minimal maintenance. A LiFePO4 battery was chosen for low weight, high power output, and high efficiency. The system was able to operate for at least half a day and charge in less than four hours. To accommodate Lane’s symptoms of muscle spasms, limited mobility, and reduced dexterity, a ramping function was integrated into the control system to mitigate jerking motions. A joystick with a ball handle was chosen as the best option for control. A physical power switch and a remote emergency shut-off button connected through a Bluetooth app were included for safety. Though some features were not fully integrated, a functioning wheelchair with a reliable mechatronic system was designed and built successfully.
