PhotoBot is an automated photographer for events. It consists of a Canon camera and Raspberry Pi mounted on a motorized robot, and an App for entering events. The Pi controls the camera, converts media, broadcasts on Wowza, moves the robot, and provides an API. Photos are processed with Clarifai to identify people. The App scans for local geofence regions using TomTom. You can enter an associated event, sign a model release with Docusign, watch a Wowza feed, snap photos, and view your pics.
