Blind people cannot identify what is in front of them.

What it does

It is a robot that moves in front of a blind person and tells them to stop when it detects an object in front of them. It then snaps a picture and sends the picture to the CloudSight API, which identifies the object and sends back the name. It then says the name of the object into the headphones.

How we built it

We built the device using a Raspberry Pi to power the whole thing. The Laboratory for Telecommunication Sciences loaned us a Roomba + Camera system that we later added another webcam to and a proximity sensor. The rear-facing webcam uses OpenCV, while the front facing camera uses CloudSight for recognition. The Roomba is powered using iRobot Create, and the whole thing is brought together by a lot of Python and heart emoticon

Challenges we ran into

  • Integration OpenCV into the main program
  • Making sure that the robot stopped when it detected an object
  • Slow WiFi

Accomplishments that we're proud of

  • Integrating a ton of data into one device
  • Finding a good image identification API

What we learned

  • How to use OpenCV
  • How to use Roomba
  • How to multithread
  • How to use Foscam

What's Next?

  • Faster Image Recognition
  • Better Footstep Detection
You can’t perform that action at this time.
