A standard catalogue model: the drawing, 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.

01 / Overview

By interacting with the exhibit, understand that the weight of the same object varies on different planets.

02 / How visitors use it

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.

03 / The science behind it

The gravitational accelerations of the eight major planets are: Mercury: gravitational acceleration of 3.70 meters per square second; Venus: gravitational acceleration of 8.87 meters per square second; Earth: gravitational acceleration of 9.798 meters per square second; Mars: Gravity acceleration of 3.71 meters per square second; Jupiter: gravitational acceleration of 24.79 meters per square second; Saturn: gravitational acceleration of 10.44 meters per square second; Uranus: gravitational acceleration of 8.87 meters per square second; Neptune: Gravity acceleration of 11.15 meters per square second.

04 / Built for a public floor

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.
