Bluetooth Remote Control

Control the robot wirelessly using a custom-built Java application. Users can move the vehicle forward, backward, left, and right in real time via Bluetooth communication.

Obstacle Detection

The robot continuously monitors its surroundings using an ultrasonic distance sensor to detect obstacles and prevent collisions during navigation.

Key Features

Autonomous Navigation

Implements basic obstacle avoidance logic that enables the robot to make movement decisions automatically without continuous user intervention in version 2.0.

Embedded System Design

Developed using Arduino with efficient embedded programming to manage sensor readings, motor control, and communication simultaneously.

System Architecture & Logic

The Arduino microcontroller receives commands either from the Bluetooth module or from the obstacle detection algorithm. Based on sensor readings and user input, the controller operates the motor driver to control the movement of the robot.
