The recently enhanced 4WD Multi-Purpose Vehicle is recognized as one of the most sought-after Arduino kits in the market. It boasts an attractive design coupled with robust functionalities. In addition to standard features such as line tracking, obstacle avoidance, and remote control, this model also incorporates facial recognition technology, enabling it to display engaging facial expressions. Moreover, it offers the flexibility to expand individual projects and integrate additional sensors, thereby facilitating comprehensive exploratory opportunities.

The components are primarily interconnected through screws and copper pillars, allowing for the assembly of a custom robot through a series of straightforward steps. Furthermore, fundamental concepts such as line tracking, obstacle avoidance sensors, ultrasonic ranging, Bluetooth communication, motor drivers, and infrared remote controls are readily available for exploration and learning.

This product features a total of 17 educational projects that range from basic to advanced levels, designed to provide comprehensive guidance in the construction of an Arduino robot.

Features

1. Versatile Functionality: This device features multiple functions including obstacle avoidance, tracking capabilities, infrared remote control, Bluetooth connectivity, confinement within a defined circular area, gravity control, and the ability to display facial emoticons.

2. Easy Assembly: The assembly process is straightforward, requiring no soldering of circuits.

3. Robust Construction: The device is designed with a four-wheel drive (4WD) system, incorporating four high-quality motors and wheels.

4. High Expandability: It is possible to enhance functionality by integrating additional sensors and modules through a motor driver expansion board.

5. Diverse Control Options: The device can be operated via infrared remote control or through an application compatible with both iOS and Android operating systems.

6. Basic Programming: Programming is facilitated using C language code within the Arduino Integrated Development Environment (IDE).

8X16 LED light board

8*16 LED light board comes with 128 LEDs. microprocessor (Arduino) data through the two-wire bus interface to communicate with the AIP1640, thus controlling the module on the 128 LEDs on and off, so that the module on the dot-matrix display needs the pattern.

Ultrasonic Sensor

The HC-SR04 ultrasonic sensor uses sonar-like a bat to determine the distance to an object. It provides excellent non-contact range detection with high accuracy and stable readings.

Bluetooth Module

The DX-BT24 is a ready-to-use Bluetooth module for establishing wireless data communications. The Bluetooth standard has undergone many upgrades to continually meet the needs of customers and technology. Over the years, many changes have occurred, including data transfer rates, power consumption of wearable and lOT devices and security systems.
