At a closed sorting station in a resource-recovery exhibition, a fixed-base robot grips the outside edge of one large metal ring as its lower edge approaches a mesh basket. The demonstrator uses the controls with a bare left hand and wears one finger guard on the foreground right hand. A student records geometric shapes on a clipboard from behind the rail. The observation table holds a grooved rubber block, magnetic wand, weighing pan, clear divider, and sealed material case, with a dustpan on the lower shelf. Flat modern color planes emphasize the open center of the ring, the basket grid, and the separate tools.
