A toy vehicle including a chassis, four running wheels, which are attached to the chassis, an activating element configured to steer the toy vehicle, and a steering device. The steering device includes a steering plate articulated onto all four running wheels. The steering plate is movable by the steering activating element relative to the chassis. The vehicle also includes four axle knuckles, each axle knuckle supporting one of the four running wheels, thee axle knuckles being articulated both onto the steering plate and also the chassis. The steering plate has a central portion extending along a longitudinal axis of the vehicle, and four cross-arms extending outwardly from the central portion, each of the cross-arms connecting to a respective one of the four axle knuckles.

A tracking toy vehicle includes a vehicle body, a left drive wheel, a right drive wheel, a sensing device installed at bottom of the vehicle body for sensing a tracking line, a controller electrically connected to the sensing device, a left driving device for driving the left drive wheel to steer, and a right driving device for driving the right drive wheel to steer. The sensing device includes a first sensor and a second sensor respectively installed on left and right sides of an axle of the vehicle body, for respectively sensing whether the toy vehicle is following the tracking line. The sensing device can identify the tracking line under the vehicle body to confirm the location of the tracking line, and then the controller changes the rotational speed of the left driving device or the right driving device to steer the toy vehicle along the tracking line.

A robotic activity system, which includes a board and an autonomous robotic device, is described herein. The board may display a line and one or more color patterns. The robotic device may traverse the line using one or more integrated sensors. For example, sensor data may include light intensity data for visible light reflected or emitted by the board. The sensor data may be analyzed to 1) ensure the robotic device follows the line and/or 2) detect color sequences associated with color patterns shown on the board. Upon detection of a color sequence, the robotic device may attempt to match the color sequence with a known color pattern definition. The color pattern definition may be associated with a function to be performed by the robotic device. Using multiple sets of color patterns and associated functions allows the robotic device to move in a variable and potentially unpredictable fashion.

A radio-controlled (RC) model vehicle system is provided including a transmitter and an RC model vehicle containing a receiver. The transmitter includes a transmitter binary large object (BLOB) parameter profile and a transmitter BLOB Version. The receiver is wirelessly, communicably coupled with the transmitter and includes a receiver BLOB parameter profile comprising RC model vehicle parameters corresponding to the RC model vehicle, and a receiver BLOB Version. Changes to the transmitter BLOB are saved to the transmitter and increment the transmitter BLOB Version by one. The transmitter is linked and bound to the receiver, and the receiver BLOB Version is compared to the transmitter BLOB Version. When the RC model vehicle is motionless and the receiver BLOB Version is less than the transmitter BLOB Version, the receiver BLOB is updated with the transmitter BLOB and the receiver BLOB Version is updated to the transmitter BLOB Version.
