This project is my contribution to a larger project called the IKRobo wheelchair research project funded by the research division at Durham College. The aim of this project is to enlighten the community about the difficulties of wheelchair use, direction of possible and probable solutions to these difficulties, and a working prototype of these solutions in place.The project is currently finishing its first phase of prototyping and is pursuing additional funding.The IKRobo has three main distinctions from the regular consumer wheelchair.
- Multiple steering choices; Joystick, Eye tracking, Object avoidance, Voice command
- Three body positions; Sitting, Walker(standing), Bed(sleeping)
- Electronic bio-medical health monitoring

The Arduino Yun was chosen for its ease of use and integration with the eHealth sensor shield from cooking hacks. Xively.com and Plot.ly were used to view and log the data to the internet. Nexmo was used to make the phone call to the caregiver
The data that is collected comes from a variety of non-invasive bio-medical sensors including: pulse rate, blood oxygen percent, blood pressure, electrocardiogram, breathing rate, weight, and temperature. These sensors are monitored by a microcontroller that sends the data via WiFi to the cloud storage. If this data falls out of range, phone calls are automatically sent to the medical adviser or caregiver.
