01 / Overview

By displaying wrist joint models of gibbons and humans, visitors can visually compare the differences in wrist joints between humans and Hainan gibbons. Try rotating the 'wrist joint' and compare the differences in wrist joints between humans and Hainan gibbons. The wrist joints of gibbons can rotate 270 degrees, like a spherical body. When swinging and leaping forward on the tree crown, the wrist rotates like a universal wheel and forms multiple angles with the arms, ensuring that they do not need to expend too much energy to adjust the posture and angle of their body and arms during rapid movement.

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 / 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.
