ZIV is a compact autonomous base with all-wheel drive and steering, a 48 V power system, a safety controller and a universal payload interface. Everything above it is a module.

Prototype reference. The humanoid module adds a torso to about 5 ft (1.52 m) overall.
Prototype reference dimensions. Subject to change before release.
Object recognition and people detection at the front of the base.
Depth perception for navigation and obstacle shapes.
360° obstacle detection with configurable safety zones.
Low-height and close objects that cameras and LiDAR can miss.
Hard-wired buttons front and rear, independent of software.
Colour and motion show what the robot is doing, readable from across a room.

A steering motor and encoder sit above a planetary gearbox, drive motor and encoder. The same module is used at every corner, which keeps spares and service simple.
A module drops onto the top plate, locks in four places and announces itself. The base reads the module, loads the matching safety profile and powers up the payload.

The chassis is a 40-series aluminium profile frame with standard brackets, plates and fasteners, so a small team can build, repair and re-spin it without special tooling. The shell is 3D printed, which lets us change the look of a module without touching the structure.
