Chrono-Orb is a modular, spherical time-traveling robot toy consisting of four main 3D-printed parts. Each component snaps together using interlocking joints. Once assembled, it forms a complete rolling orb. Inside the orb is a mechanical gear system with a spring-loaded motor. When pulled back, it stores energy and rolls forward when released. A transparent window allows kids to see the spinning gear action.

The orb splits open to reveal a small “robot pilot” figure, also printable via 3D printer.This concept offers a never-before-seen play experience: a spherical rolling toy that transforms into a robot capsule!
