Abstract: A mobility device having a body, a plurality of arms, and a control module operable to control the angular positions of the plurality of arms and the body. The body includes a first side, a second side, a front end, a rear end, a first frame rotatable about a first axis, and a second frame rotatable about a second axis. The first axis is parallel to the second axis. Rotation of the first frame causes simultaneous rotation of the second frame in the opposite direction. Arms are rotatably supported on the first side of the body and other arms are rotatably supported on the second side of the body. Each arm includes a wheel. The arms are independently rotatable from the other arms.

Abstract: An animatronic doll having a motor, a head frame pivotally mounted to a neck carrier, a bevel gear and a pinion gear connected to a head shaft, a first gear, and a second gear. The pinion gear is engaged with a rack of the head frame. The first gear is configured to be driven by the bevel gear and is rotatable between a first position, a second position, and a third position. The first gear does not drive the second gear when the first gear is rotated between the first position and the second position. The first gear drives the second gear when the first gear is rotated between the second position and the third position. Rotation of the head shaft rotates the pinion gear and pivots the head frame. Rotation of the second gear may rotate arms of the doll. The arms may include friction clutches.

Abstract: A multiple-output transmission includes a drive motor and one or more stacked layers. Each layer includes one or more output gears, a drive gear, coupled to be driven by the drive motor, at least one idler gear, engageable with the drive gear, and means for indexing the at least one idler gear between multiple selectable indexing positions, thereby to selectively engage one or more of the output gears.

Abstract: A hand-held flinging device includes a launcher that engages the projectile and improves control of the launcher and projectile, during a throwing/flinging motion, until centrifugal force causes disengagement of the projectile from the launcher. The engagement system involves the rearward portions of a launcher shaft and the projectile bore, so that, upon disengagement, frictional engagement and interference of the engagement system with the projectile is prevented or limited as the projectile moves forward to fly off the launcher. The engagement system may include a member that snaps into engagement with a hole or recess to hold the projectile on the launcher even through the wind-up portion of the throw that may include the launcher distal end being pointed downward. The preferred projectile covers the entire or nearly the entire launcher shaft distal of the hand grip and is heavier toward its front end.

Abstract: A system for remote interaction with a pet is provided which may include a home computer connected to a movable turret. The turret has rotary components driven by a servo-motors to direct a laser to the floor to create shapes depending on the play to be performed, such as images on the floor or lines defining various shapes that may be shifted, contorted, or changed in shape to amuse a pet. The user can position, rotate and scale the shaped path within the environment provided by the floor area and can control the animation speed, play and pause as well as set the apparatus in a play mode to loop forward and backward through a shaped path. Video and audio including the pet owner's voice may be introduced to further entertain the pet while he or she is home alone.

Abstract: A robot may be made to operate in response to changes in an environment by determining a currently dominant drive state for the robot from a plurality of competing drive states, sensing a change the environment, selecting an appropriate behavior strategy in accordance with the currently dominant drive state from a database of behavior strategies for response by the robot to the sensed changed, selecting one or more robotic motions to be performed by the robot from a database of robotic motions in accordance with the selected strategy and causing the robot to perform the selected robotic motions.

Abstract: The present invention provides various clutch/gear assemblies that can be driven by a single motor. The clutch/gear assemblies comprise a smart material which changes shape when supplied with energy, e.g., current or heat. The smart material achieves one of a first or a second shape when supplied with energy, and achieves the other shape when it is not supplied with energy. When the smart material achieves a first shape it causes a clutch surface of the clutch/gear to engage and be driven by a shaft coupled to the motor and when the smart material achieves a second shape it allows the clutch surface to disengage from the shaft.
