PetRobotA friendly robot that talks, remembers and finds its way.
PetRobot is an assistant robot for homes and public spaces like libraries. Say “Hey Jarvis” and it turns to face you, answers out loud, and can lead you where you need to go.
See it in action
A short demo of the current prototype.
What it does
The project is under active development. Each item is marked with where it stands today.
Natural conversation
Wakes on “Hey Jarvis”, turns toward the speaker, and answers by voice with an animated face on its touchscreen.
Knows who it's talking to
Recognises returning people by face and voice and greets them by name.
Guides you to places
Maps its surroundings with a lidar and drives itself to named spots on request.
Reminders and timers
“Remind Jane to take her medicine every Monday at 9 PM” — and it does, out loud.
Photos
Takes a picture on request with a live preview and countdown on screen.
Short lessons
Teaches a topic step by step with slides on its screen and quick questions, and remembers your progress.
Learns by watching
Show it a task once; it saves the steps with photos and can walk someone else through it.
Remembers many places
Keeps a separate map for each place it works in, including the objects it has seen there.
Library assistant
A pilot in a university library: help students find books and lead them to the right shelf.
