Summary:
The purpose of this capstone was to not only create a sensor system which was capable of detecting obstacles in a user’s path and notify them, but to also keep the price of the device low enough that feasible anyone could afford it.
The motivation for this project was that while systems such as the one conceived already exist, they can cost upwards of hundreds of dollars. By keeping the cost of our system around or optimistically under one hundred dollars will mean that people who could otherwise not afford the more costly systems could still get the help they need if their vision is compromised enough to need aid.
The final design for the system has a single Arduino control board, three MaxBotix sensors, and an Adafruit waveshield. Two of the sensors will be worn on the users head detecting obstacles that the user may be looking at. The third sensor will be with the Arduino board in the control unit worn on the waist. It will be aimed downwards at an angle to check for drop offs and ledges. The waveshield will allow for auditory warnings to be sent to the user when an obstacle is detected.
