Abstract: An apparatus includes a fixed base, a platform supported by the fixed base, and a mechanism for causing vibration coupled to the platform and adapted to induce vibration of the platform sufficient to cause a vibration-powered vehicle to move across the platform without relying on an internal power supply of the vehicle. In some cases, a substantially planar cover is situated approximately parallel to the platform and spaced apart from the platform at a great enough distance to allow the vibration-powered vehicle to move across the platform and at a low enough distance to deter the vibration-powered vehicle from turning over.

Abstract: A vibration-powered device adapted for flotation and propulsion on an upper surface in a liquid. The device having a body with a top side adapted to be at least partially disposed above the surface of the liquid, and a bottom side adapted to be at least partially submerged below the surface of the liquid. A vibration mechanism is disposed in the body. A propulsion fin is connected to the body. The fin includes a top side adapted to be disposed at least partially above the liquid surface, a bottom side adapted to be disposed at least partially below the surface. The vibration mechanism is adapted to oscillate the free distal end of the propulsion fin upward and downward.

Abstract: A playset system for autonomous devices includes a communal area including a substantially horizontal and substantially planar area bounded by a plurality of side walls, a plurality of connectors, and a plurality of ports. Each port is disposed in a side wall, each port is situated adjacent to one of the connectors, and each port includes a gate adapted to open and close, to impede movement of the autonomous devices when closed, and to allow passage of the autonomous devices when open.
