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: An apparatus includes a housing, a rotational motor situated within the housing, an eccentric load adapted to be rotated by the rotational motor, and a plurality of legs each having a leg base and a leg tip at a distal end relative to the leg base. The legs are coupled to the housing at the leg base and include at least one driving leg constructed from a flexible material and configured to cause the apparatus to move in a direction generally defined by an offset between the leg base and the leg tip as the rotational motor rotates the eccentric load.

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.

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: An apparatus includes modular track sections adapted to be assembled into a track for autonomous vehicles. The track is configured such that the vehicles tend to stay on the track and that allows the autonomous vehicles to enter and exit the track from at least one side of the track.

Abstract: An apparatus includes an appendage rotatably coupled to a body of a device adapted to move based on internally induced vibration of the device. The appendage can be attached directly to the body of the device or to a frame that is adapted to releasably attach to the device. The appendage is adapted to rotate about an axis of rotation as vibration induces motion of the device. The device can include a body, an eccentric load, a rotational motor coupled to the body and adapted to rotate the eccentric load, and a plurality of legs each having a leg base and a leg tip at a distal end relative to the leg base. At least one driving leg configured to cause the apparatus to move in a direction generally defined by an offset between the leg base and the leg tip as the rotational motor rotates the eccentric load.
