This Robot Generates Emotions in Real Time

Описание: On-the-fly emotion generation by one of my students!

The emotions on Reachy Mini are pre-recorded. They work, but they can feel repetitive.

So I gave a project at #EnseirbMatmeca to explore new ways to generate expressive motion on the fly. I'm proud to showcase the work of one of my engineering students, Anaelle Jaffré, who coded a simple system that procedurally generates emotions in real-time.

She mapped the emotions using the PAD model (Pleasure, Arousal, Dominance), then used a bunch of heuristics to generate sound and motion (with lots of randomness built in). Notice in the video how "anger" is different on the second request?

The result is a bit weird, but I like it a lot. I believe this approach has real potential for making human-robot interaction feel more natural and believable.

Everything is open source. I'd be very happy if someone continued this work :)

(My contribution was just adding the graphical interface and integrating it into the conversation app, all the cool stuff is Anaelle’s work!)
