Otto Auto Dock – Magnetic USB-C Charging & Programming Station

This project is a charging and programming dock for the HP Robots Otto , designed to work with a magnetic USB-C cable .

The dock allows Otto to:

- Drive into position

- Automatically align

- Snap into place via magnets

- Start charging or connect to a computer

Features

- Magnetic USB-C auto-connection

- Self-alignment ramp + guide system

- Works for charging AND programming

- Designed for future autonomous docking

- Fully 3D printable structure

Design Concept

The system uses passive mechanical alignment + magnetic attraction :

Key Elements

- Front ramp → guides wheels into position

- Side wall → aligns lateral position

- Back plate → defines final stopping point

- Magnetic USB-C tip → snaps into Otto

This ensures consistent docking even with small positioning errors.
