Abstract: An unmanned vehicle is provided that includes a housing configured to rotate about a rotational axis. The housing supports a pendulum drive assembly having coaxial first and second drive axles that are coaxially aligned with the rotational axis. A first rotating member is mechanically coupled to the first drive axle and configured to rotate with the first drive axle. A second rotating member is mechanically coupled to the second drive axle and configured to rotate with the second drive axle. The pendulum drive assembly includes a first electrical motor and corresponding first transmission system that are operably coupled to the first drive axle as well as a second electrical motor and corresponding second transmission system that are operably coupled to the second drive axle.

Abstract: The disclosure relates to the technical field of toy vehicles, in particular to a pull back vehicle capable of switching travelling lines including a pull back vehicle chassis. The pull back vehicle chassis includes a driving gear box, driving wheel, a driving gear, a steering wheel shaft, steering wheels and a centering spring. The pull back vehicle chassis is fixedly installed with the driving gear box, the driving gear box is fixedly connected with a driving axle, the driving axle is fixedly connected with the driving gear, and the driving axle is fixedly connected with the driving wheel, and the pull back vehicle chassis is fixedly connected with the steering wheel shaft.

Abstract: A ball robot formed from a spherical shell includes a main axle, first and second pendulums pivotally coupled to the main axle, and a drive mechanism for the first and the second pendulums. The drive mechanism drives the first and second pendulums together in a first rotational direction to move the ball robot forward and backward and in opposing directions to cause the ball robot to turn right or left. In an alternative embodiment, a flywheel is used to provide forward and backward movement and a pendulums is used to cause the ball robot to turn right or left.

Abstract: A method of actuating a robotic mechanism having a first leg member rotatably coupled to a first side of a chassis and a second leg member rotatably coupled to a second side of the chassis. The method comprises positioning the first leg member and the second leg member generally about 180 degrees with respect to each other and effecting movement of the chassis by rotating both the first leg member and the second leg member with respect to the chassis.

Abstract: A developmental toy for small children includes a contacting member is rotated by an electric motor and a controller that, in response to input from a sensor, signals the electric motor to move the toy from a starting position for an initial period of time in an initial direction and signals the motor to wait a resting period of time. If no further input is received from a child that is detected by the sensor within the resting period of time, the controller signals the motor to move the toy back in an opposite sense, toward the starting location.

Abstract: A toy includes a platform, a moving body, and a balance bar. The moving body has front and rear wheels rotatable about horizontal rotary axes, a turning wheel, and a drive unit coupled to the turning wheel and one of the rear wheels to drive movement of the moving body when the moving body is disposed on the platform. The turning wheel is rotatable about an axis perpendicular to the rotary axes of the front and rear wheels, and prevents the moving body from falling off the platform when the moving body moves to a peripheral edge of the platform. The balance bar has an intermediate fulcrum portion mounted pivotally on the moving body about a horizontal pivot axis, and two arm portions projecting from two opposite lateral sides of the moving body.

Abstract: A self-righting remote control vehicle including a chassis, paired front and rear wheels rotatably mounted on the respective left and right sides of the chassis, and an upwardly tapered, generally pyramidal-shaped body mounted on the chassis. Each of the wheels has a peripheral portion which extends beyond the lower rear and side edge margins of the body such that when the vehicle is rolled over, a portion of at least one of the wheels normally engages the supporting surface. The vehicle further includes two separate drive systems for respectively rotatably driving the left and right pairs of front and rear wheels, and still further includes a remote control receiver for receiving control signals from a remote control transmitter and a controller for selectively independently controlling the separate drive systems responsive to the control signals received.

Abstract: A self-propelling rolling toy includes a transparent spherical outer casing, a coupling rod provided in and coupled non-rotatably to the outer casing, a horizontal transmission shaft mounted rotatably in the outer casing, an inner body mounted rotatably on the shaft inside the outer casing, a clutch operable to lock selectively the inner body to the outer casing, and a winding-type driving unit disposed in the inner body. The driving unit includes a spiral energy spring with an innermost end coupled to the shaft and an outermost end coupled to the inner body, a ratchet and pawl unit provided on the shaft, and a gear set which couples the ratchet and pawl unit and the coupling rod.

Abstract: A toy car includes a chassis, a power supplying mechanism disposed on the chassis, a cover attached to and above the chassis, a swinging unit mounted swingably on the cover, a cam wheel disposed rotatably on the chassis, and a driving wheel unit. A transmission is disposed between the power supplying mechanism and the cam wheel and between the power supplying mechanism and the driving wheel unit so as to rotate the driving wheel unit and the cam wheel by actuation of the power supplying mechanism and so as to reverse the rotational direction of the driving wheel unit and the cam wheel upon collision of the car with a stationary object. A follower unit interconnects the swinging unit and the cam wheel so as to rotate the swinging unit between a first position and a second position relative to the cover upon rotation of the cam wheel on the chassis in a first direction.

Abstract: A child's motor powered vehicle utilizes a unidirectional electric motor supported on a drive shaft which carries at its ends drive members which are engageable with either one of a pair of radially spaced drive surfaces on the drive wheels. Control levers support the drive shaft adjacent its ends and are pivotally supported on the vehicle so that they may effect movement of the drive shaft end portions and the drive elements from one drive surface to another to effect a reversal in the direction of rotation of the drive wheels. The drive surfaces are conveniently provided by axial walls of a concentric channel on the inner face of the drive wheels.

Abstract: A reversing mechanism for a toy motor driven wheeled vehicle having a driven axle with attached wheels supported on a chassis. The axle is supported on the chassis so that it is shiftable laterally relative to the chassis. The reversing mechanism includes an apparatus to shift the driven axle laterally relative to the chassis between forward and reverse driving positions upon engagement of the front or rear of the vehicle with the firm obstructing object. A pair of spur gears are positioned on the driven axle and are spaced in generally fixed relation to each other with each gear freely rotatable on the driven shaft. The shaft is freely slidable through the gears. A clutch member is affixed to the driven axle for rotation therewith and is positioned between the spur gears. The clutch member has rotationally opposite effective one-way clutch teeth on the sides thereof facing the spur gears.
