EMOJI COMPANIONS / ESP32-S3

VisionGive your companion a new perspective.

Vision adds a camera and a separate virtual AI host to an ESP32-S3 companion. Study how observation, expression and control can fit together before choosing the hardware for a connected robot.

YOUR FIRST THREE EXPERIMENTS

Build understanding.
One change at a time.

Use the starting assembly to ask better questions about your design. Save a copy, change a parameter and compare what happens.

Inspect the design

Inspect the camera's power and data path to the virtual AI host.

Try a change

Try a rendered camera observation in the AI workspace with your own provider key.

Compare and learn

Change bounded servo targets and display behavior; audio remains a text-event abstraction.
