A children's toy includes a base having an upper portion and a lower portion and a driving mechanism operably connected to the lower portion of the base. The driving mechanism is configured to move the base along a plurality of paths. One or more lights operably connected to the base are configured to display a patterned light display as the base moves along one of a plurality of paths. A removable member is also included for placement on the base with a sensor on the base triggered by the removable member which affects the path of the base.

A self-propelled device can include at least a wireless interface, a housing, a propulsion mechanism, and a camera. Using the camera, the self-propelled device can generate a video feed and transmit the video feed to a controller device via the wireless interface. The self-propelled device can receive an input from the controller device indicating an object or location in the video feed. In response to the input, the self-propelled device can initiate an autonomous mode to autonomously operate the propulsion mechanism to propel the self-propelled device towards the object or location indicated in the video feed.

A ball-balancing robot is capable of accurately controlling its posture when a robot main body is rotated about the vertical axis in a yaw direction in a state in which the robot main body is positioned on a spherical object in a posture in which a gravity center of the robot main body matches a vertical axis passing a center of the spherical object, and in a state in which a base axis of the roll-direction angular velocity sensor is inclined with respect to the horizon in a pitch direction (at an inclination angle .sub.p), the robot main body is able to rotate while maintaining a predetermined posture by making correction to cancel a detection error in the angular velocity in the roll direction generated based on the inclination of the base axis of the roll-direction angular velocity sensor.

A self-propelled device includes a spherical housing and an internal drive system. The self-propelled device can further include an internal structure having a magnet holder that holds a first set of magnets and an external accessory comprising a second set of magnets to magnetically interact, through the spherical housing, with the first set magnets

The Rollback Ball or Ballmerang is a ball toy consisting of a ball shell and a mechanical tracking device tracking the ball shell by using friction force or magnetic force converting the moving ball kinetic energy to potential energy, and then releasing the potential energy rolling the ball back at the same straight line path to the same launching destination when rolling the ball in any direction on a flat floor.

A modular assembly toy system includes assembly modules each including at least one connection interface and one or more connectors each configured to mechanically and electrically connect two of the assembly modules via the respective connection interfaces. The assembly modules include a control module and an analyzing module. The control module includes a control module communication unit configured to obtain a set of host instructions from one or more hosts and a control module processor configured to generate a set of operation instructions for control each assembly module based on at least the set of host instructions. The analyzing module includes an analyzing module sensor configured to obtain a sensor signal, an analyzing module processor configured to analyze the sensor signal to generate a first analyzing result, and an analyzing module communication unit configured to transmit the sensor signal or the first analyzing result to at least one of the hosts.

In one embodiment, a neuromorphic robot includes a curved outer housing that forms a continuous curved outer surface, a plurality of trackball touch sensors provided on and extending across the continuous curved outer surface in an array, each trackball sensor being configured to detect a direction and velocity a sweeping stroke of a user, and a plurality of lights, one light being collocated with each trackball touch sensor and being configured to illuminate when its collocated trackball touch sensor is stroked by the user, wherein the robot is configured to interpret the sweeping stroke of the user sensed with the plurality of trackball touch sensors and to provide immediate visual feedback to the user at the locations of the touched trackball touch sensors.

A self-righting aeronautical vehicle comprising a hollowed frame and a lift mechanism. The exterior of the frame and center of gravity are adapted to self-right the vehicle. The frame can include sealed, hollowed sections for use in bodies of water. The frame can be spherical in shape enabling inspection of internal surface of partially or fully enclosed structures. Inspection equipment can be integrated into the vehicle and acquired data can be stored or wirelessly communicated to a server. A controlled or other mass can be pivotally assembled to a pivot axle spanning across the interior of the frame. The pivot axis can rotate about a vertical axis (an axis perpendicular to the elongated axis). The propulsion mechanisms can be adapted for use as a terrestrial vehicle when enclosed in a sealed spherical shell.

A system produces bubbles. The system may be used as a children's toy, a special effects machine, an art performance prop, a party entertainment item, or a similar object for entertaining users. The system is designed to produce bubbles regardless of the orientation of the system. The system includes a reservoir, a pump, a swiping mechanism, and a fan. The reservoir receives and stores fluid, and the pump provides pressure on the stored fluid such that the fluid travels through the reservoir and exits the reservoir. The swiping mechanism spreads across the exited fluid to create a fluid sheet, and the fan blows on the fluid sheet, transforming it into a bubble. The pump enables the stored fluid to be available for bubble production at any orientation of the system. The system may be moved, rotated, thrown, bounced, swung, etc. by a user and produce bubbles during its motion.

A multi-body self-propelled device can include a drive body and a coupled head. The drive body can include a spherical housing, an internal drive system within the spherical housing to propel the multi-body self-propelled device, and a magnet holder coupled to the internal drive system to hold a first set of magnetic elements. The drive body can further include a first power source within the spherical housing to power the internal drive system and a first inductive interface. The coupled head can include second set of magnetic elements to establish a magnetic interaction with the first set of magnetic elements through the spherical housing. The coupled head can also include a second power source, and a second inductive interface. The multi-body self-propelled device can transfer power between the coupled head and the drive body via the first and the second inductive interfaces.
