The present invention provides a method for self-righting a remote controlled model vehicle. The method includes determining a current pitch angle and a current angular rocking rate of the model vehicle. The method further includes accelerating or decelerating a mass on the model vehicle based on the current pitch angle and the current angular rocking rate of the model vehicle to create a rocking motion about a first axis by the model vehicle. In addition, the method may include sensing a rotation about a second axis of the model vehicle and imparting a yaw moment to realign the model vehicle to rock about the first axis. The method may also include terminating the self-righting process when the model vehicle is upright.

Robotic systems include a frame or body with two or more wheels rotatably mounted on the frame or body and a motor for independently driving each wheel. A system controller generates a signal for actuating each motor based on information provided by one or more sensors in communication with the system controller for generating feedback signals for providing reactive actuation of the motors for generating one or more functions selected from the group consisting of forward motion, backward motion, hopping, climbing, and balancing. A power source is included for providing power to operate the drive motors, system controller and the one or more sensors.

An aeronautical vehicle that rights itself from an inverted state to an upright state has a self-righting frame assembly has a protrusion extending upwardly from a central vertical axis. The protrusion provides an initial instability to begin a self-righting process when the aeronautical vehicle is inverted on a surface. A propulsion system, such as rotor driven by a motor can be mounted in a central void of the self-righting frame assembly and oriented to provide a lifting force. A power supply is mounted in the central void of the self-righting frame assembly and operationally connected to the at least one rotor for rotatably powering the rotor. An electronics assembly is also mounted in the central void of the self-righting frame for receiving remote control commands and is communicatively interconnected to the power supply for remotely controlling the aeronautical vehicle to take off, to fly, and to land on a surface.

In one aspect, there is provided a toy vehicle that includes a vehicle body, at least one motor and a plurality of wheels. The at least one motor is mounted to the vehicle body, and is sized to have a selected amount of torque. The plurality of wheels includes at least one driven wheel which includes at least one flip-over wheel which has an axis closer to one end of the vehicle than the other end. In an upright orientation the vehicle body extends above the plurality of wheels. The toy vehicle has a centre of gravity that is positioned, such that, application of torque from the at least one motor causes the vehicle body to drive rotation of the vehicle body about the axis of rotation from an inverted orientation over to the upright orientation.

A self-righting flier includes a battery residing at a rounded bottom of a flier body, propellor blades and louvers below the propellor blades. The louvers include rounded projections extending down of bottom most corners. The bottom location of the battery and the louvers provide the self-righting of the flier. The flier further includes a top most guard preventing or reducing damage from ceiling impacts.

A roly-poly toy with adjustable center of gravity, comprising a first and second base part arranged at an interval, a first winding mandrel mounted on the first base part, a second winding mandrel mounted on the second base part, a reel belt, and a drive assembly. The reel belt is annular and has a first end wound around the first winding mandrel and a second end wound around the second winding mandrel. The drive assembly can switch between a first driving state and a second driving state. When the drive assembly is in the first driving state, the first winding mandrel rotates to roll up the reel belt, and the second winding mandrel rotates to release the reel belt. When it is in the second driving state, the second winding mandrel rotates to roll up the reel belt, and the first winding mandrel rotates to release the reel belt.
