Raspberry Pi Robot That Reads Your Emotions

It’s getting easier and easier to add machine intelligence to your hacks, even to the point where you sometimes don’t have to install any special software. In this case [Dexter Industries] has added the ability to read human emotions to their EmpathyBot robot by making use of Google Cloud Vision.

Press a button on the robot and it moves forward until it’s a certain distance from an object. It then takes a picture and sends it off to Google Cloud Vision along with a request to do face detection. The response that Google returns is in JSON format and, if it finds a face, includes the likelihood of the face being happy, sad, sorrowful or surprised. The robot parses that response and gives an appropriate canned speech using the text-to-speech software, eSpeak e.g. “You seem happy! Tell me why you are so happy!”.

[Dexter] has made the source code available on github. It’s written in python and is easy to read by anyone with even just a little programming experience. The video after the break gives a number of demonstrations, including some with non-human subjects.

Aural Twitter

[POTUSCamacho] listens to his @public_timeline rss feed. In part one of his project, he describes creating a bash script in which he uses cURL get his private feed, sed to clean it and eSpeak to output a WAV file. In parts two and three, he goes on to discuss how he created an audio stream (currently down, opens in a new window) of @public_timeline and how he plans on tweeting vocally.
