A standard catalogue model: the dimensions, control package and finish are fixed, which is what keeps the price and the lead time predictable. Size, colour and interface language can be adapted without a new design cycle.

Around 3500 BC, the wheel was created by humans. The earliest wheels were used for pottery and textiles, and later they began to be combined with axles. The emergence of wheels catalyzed the development of civilization, which in turn led to the evolution of wheel forms. The exhibits visualize the appearance and structure of wheels in different periods from the perspective of models based on the timeline, intuitively demonstrating the birth and step-by-step evolution of wheels.
The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.

Blade pitch adjusted by hand with thrust read on a live gauge.

Time four signals so a bus crosses the city without stopping.

Load a hull until it floats and then until it does not.

Road-side sensing, lane markings and vehicle communication in one model.
Attach a theme outline, a floor plan, or nothing at all — a photo of the space is enough to start. Quotations are issued against a real exhibit list, not per-square-metre guesses.
