Project Overview:
Intelli-walk is a smart cane used for assisting the visually impaired. The cane design contains a moving base with multiple rangefinders to sense obstacles ahead. The cane also contains walking paths stored as GPS coordinates that can be retraced by the cane to aid in frequently walked paths.
Project Specific Success Criteria:
- An ability to read and write motor encoder data in non-volatile memory.
- An ability to record and playback audio corresponding to path names
- An ability to detect obstacles within 2 meters ahead of the user using an array of Ultrasonic sensors
- An ability to move the base in the X/Y plane for an input speed provided by the microcontroller
- An ability to choose from a selection of stored paths
