A control system to locate a motorized entity on a display having an electronic device with a display is provided. The electronic device may include a microphone and an electronic device integrated circuit with a set of entity locating software instructions with a capability to generate and display a sequence of pixels in a location pattern, and to further receive an audio output detection signal from the microphone. The entity may include a speaker and one or more sensors in communication with an entity integrated circuit including a set of entity control software instructions. The one or more sensors may be capable of detecting pixels and to send a pixel detection signal to the entity integrated circuit upon detection thereof.

A process for self-righting an inverted remote controlled model vehicle is provided. The process includes the method of determining a current pitch angle and a current angular rocking rate of the model vehicle and 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 by the model vehicle. In addition, the method also includes terminating the self-righting process when the model vehicle is upright. In which, the model vehicle body contacts the ground and provides a fulcrum for the rocking motion by the model vehicle.

Provided is an educational toy that enables even an infant of low age to easily play with interest. One or a plurality of command panels 121 are arranged to form a moving path 120, the command panels 121 including command information readable by a reading module. The movable robot 110 sequentially reads, using the reading module, the command information included in the command panel 121 over which the movable robot 110 passes, while moving on the moving path 120, and sequentially performs an action corresponding to the read command information. The actions performed by the movable robot 110 include at least any one of starting a movement, stopping the movement, rotating, changing a moving direction to a predetermined direction, flashing a light emitting portion of the movable object in a predetermined color, and replaying sound.

An electronic system for stabilizing steering of a model vehicle may use different settings depending upon the RC model vehicle to be controlled. Different vehicles have different dynamic operation and responses and therefore may require different Electronic Steering Stability (ESS) system settings. The settings may be different gains, or different coefficients used with the control system algorithms. Settings may also mean that a completely different control algorithm may be used. For example, a vehicle A may be controlled adequately with a P control algorithm, while a vehicle B may require a complete PID control algorithm to be implemented.

An apparatus has a chassis that has a pair of rear wheels that passively rotate and a pair of front wheel sets. Each pair of front wheel sets has an upright with an affixed motor. A front wheel is fixed relative to the upright and engages with the motor. A linkage connects the chassis to each of the uprights and is configured to move the uprights in a first range of motion. A linkage actuator actuates the linkage.

An electronic system for stabilizing steering of a model vehicle may provide a curvature steering control of an RC vehicle. The approximate curvature control of the RC vehicle determined using error integration to achieve full steering. Application of a leaky integrator may be used to minimize steering memory. The leak factor may be based off gain scheduling of the steering input.
