Using water-floating 3D-printed models, we investigated the dynamics of camphor boats, which are composed of a one-holed board and a camphor grain, under constraint conditions where a rod hooks the camphor boat on the water surface. When a camphor boat was connected to a water-floating disk or another camphor boat through a rod, we found that regular dynamics of the camphor boat appear and depend on the mobility restriction of the disk, the rod length, and the position of a slit of the camphor boat. We performed numerical simulations to reproduce the observed motions with theoretical models including constraint conditions.
