Sensors and Motors

The 4 outputs will be attached to an EV3 brain. The truck will need a small motor to move the wheels and a GPS module to interact with the alert location. The truck will need a distance sensor to detect obstructions. Additionally, it will also need LED lights turning ON and OFF as well as audio outputs to simulate a siren.

Ports

Crime Truck will require two output ports on an EV3 hub to connect a motor and LED lights.

Variables/Settings

Status: Can be set to "on" or "off". When there is an alert in the city.

Pseudocode

In this example, the location is only available when recently requested:

While True

    If status == “ON"

        Start motor and Light

        Go to the alert location using the GPS

        Stop motor and light

    else status == “OFF”
