System

Touchscreen Display (Top Left)

Function

Used as a user interface to display rover operations and status.Connection

Connected to the WiFi module (M5Atom) via UART (Universal Asynchronous Receiver-Transmitter).WiFi Module (M5Atom) (Top Center)

Function

Transmits instructions from the touchscreen display to the rover via wireless communication.Connection

Connected to the touchscreen display via UART and to the controller (M5AtomMotion) for generating PWM (Pulse Width Modulation) signals.Joystick (Bottom Center)

Function

Input device for manual rover operation by the user.Connection

Connected to the WiFi module to relay user operations to the rover. Sends joystick operation information to the touchscreen display via UART for UI display.PWM Controller (M5AtomMotion) (Center Right)

Function

Receives instructions from the WiFi module (M5Atom) and generates PWM signals to control the rover's motors and servo motors.Connection

Connected to the WiFi module and sends PWM signals to the rover's drive system and servo motors.Rover (Tamiya Arm Crawler) (Top Right)

Function

A mobile platform equipped with a rubber band gun. Receives PWM signals and drives motors for movement.Connection

Receives signals from the PWM controller.Servo Motor (Bottom Right)

Function

Controls the movable parts of the rubber band gun's firing mechanism.Connection

Receives signals from the PWM controller. Positions rubber bands every 30° and fires 6 rubber bands over 180°.

Movie

Story

It would be incredibly emotional if we could recreate the scene described by DALL-E (AI), and boys would definitely love this kind of thing!So, I created a crawler-type radio-controlled vehicle that combines three things boys love: RC cars, a rubber band gun, and a remote control with a cool GUI.Watching children play repeatedly, creating various uneven terrains and targets, I feel satisfied that the three sleepless nights I spent rushing to complete this were well worth it.
