Qubit
Help me build a robot.
He's 14 inches tall, and an iPhone is his brain and his face. He's designed in CAD. Your coffee buys the parts for the first real one.

The robot
Every part of him is already drawn.
- The iPhone runs him, and Qubit lives on its screen.
- Its LiDAR maps the room.
- Two joints nod his head and flip the phone round.
- He rolls on two side wheels and a caster.
- An ESP32 in the base takes the phone's orders.
- Qi2 keeps the phone charged.

The AR app
He'll meet you before he's real.
An iPhone app will stand a life-size Qubit on your floor. He'll map the room with LiDAR, drive around your furniture, and talk to you in his real voice.
