A method and system for activating and canceling a first or second turn signal indicator for an R/C vehicle are provided. The method may include determining that the R/C vehicle is stationary and reading a rotation of a steering input to a stationary activation threshold. In addition, the method may include activating the turn signal indicator on a side of the R/C vehicle and setting an active turn signal indicator to on. Further actions in the method may involve determining that the R/C vehicle is in motion and reading a rotation of the steering input to a moving initiation threshold. Still further actions may include reading a rotation of the steering input in another direction to a moving cancellation threshold and deactivating the first or second turn signal indicator and setting the active turn signal indicator to off.

A method of determining a state of a model vehicle using an electric motor is provided. During a sample period, the method may include measuring raw variables, including determining a first and a second voltage relative to a battery ground. Further, the method may include extracting state variables from the first and second voltages. The measuring of the raw variables may be repeated until the end of the sample period. The method may also include determining a tentative state from the state variables. Still further, the method may include setting a model vehicle state equal to a tentative state if the tentative state is equal to a previous tentative state. Still further including actuating a model vehicle component based upon the model vehicle state and setting the previous tentative state equal to the tentative state. Additionally, the method may include repeating the process for another sample period.

Mobile agents automatically manipulate components such as blocks on a working surface, to perform operations such as construction of generalized structures. The working surface and/or the components can have machine-readable codes to assist the agents in maintaining current knowledge of their respective locations. Agents identify components by type and location, and can move components according to directions; such directions can be provided by a user, or can be based on a pre-programmed directive, or can be determined dynamically based on current conditions or in response to actions of other agents. Agents may cooperate with one another. Agents can also respond to changes in the environment, alterations in works in progress, and/or other conditions, and may be configured to exhibit responses simulating emotional reactions. Different mobile agents can be associated with different character traits, which may be configured to change based on environmental conditions and/or the behavior of other mobile agents.

A remote control vehicle includes a vehicle body and an acoustic vibration detection device. The vehicle body includes a protection cover. The acoustic vibration detection device is located at a side of the protection cover away from an external surface of the protection cover and configured to detect acoustic vibration generated when the protection cover is hit by an external object. The acoustic vibration detection device includes a housing body, a damping assembly, and an acoustic sensor. The housing body includes a chamber. The acoustic sensor includes a microphone arranged in the chamber through the damping assembly.

A robotic system is integrated with one or more mobile computing devices. Physical configurations of individual components of the system in physical space, or agents, under control of a user or users, are duplicated in a representation in virtual space. Some degree of real-time parity is maintained between the physical and virtual spaces, so as to implement a virtual environment that mirrors the physical one. Events occurring within one environment can directly influence and bear consequence on the course of events occurring within the other environment. Elements of virtual space thereby become truly interdependent and unified on a peer footing with elements in physical space. In at least one embodiment, the system is implemented as an application in entertainment, such as the manifestation of a video game in physical space.

A toy vehicle control mechanism for performing stunts includes a rod permitting a user to selectively manipulate a toy vehicle. The rod includes a rod-tip and a shaft, and a connection piece is secured to a toy vehicle as an interface for the rod-tip. The rod-tip is formed to include an opening having a shape and a size so that the connection piece can travel around within the opening and a notch at a tip edge of the rod-tip such that the toy vehicle can be manipulated by selectively engaging the notch with various portions of the connection piece, the notch having a shape and a size permitting a selected portion of the connection piece to enter into the notch without the selected portion of the connection piece penetrating into the opening.

A computer-controlled toy vehicle that provides two distinct modes of play: 1) a roll-around play mode where a child pushes the vehicle around which causes the wheels to slowly rotate and may receive audio/visual feedback related to manual the manipulation of the vehicle in a mode/operation appropriate for the roll-around play mode, and 2) a race play mode where the child pushes the vehicle quickly/vigorously (an increased velocity and/or acceleration) causing the wheels to roll or accelerate more quickly/vigorously. An ON/OFF or grip detector may gate determination of sequencing state and output results.
