Image Recognition of SortBot


SortBot comes with a camera that takes a photograph of the object placed in the tray. Using the Cloud Vision API, it interprets the images and assigns comprehensive keywords. The smart algorithm then sorts it into the correct category. SortBot is even able to identify and sieve out contaminated materials that contain food!
