01 / Overview

The exhibits mainly showcase the maturity of modern robot control technology by using humanoid robots to play piano instruments and perform familiar and pleasant music.

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

Piano robots mainly rely on 6-degree-of-freedom robotic arms to perform music pieces. A typical robotic arm consists of seven metal components that are connected by six joints. Computers will rotate stepper motors connected to each joint separately to control robots (some large robotic arms use hydraulic or pneumatic systems). Unlike regular motors, stepper motors move precisely in increments. This allows the computer to accurately move the robotic arm, causing it to repeatedly perform identical actions. Robots use motion sensors to ensure that they move completely in the correct amount.

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.
