Introduction

Automation and robotics are integral parts of modern technological advancements. The ability for a robot to perceive its environment and react accordingly is fundamental in developing autonomous systems. The present project explores the creation of a simple obstacle-avoiding robot, as a practical application of embedded systems and sensor integration. Using accessible materials like cardboard and readily available electronic components, the project aims to demonstrate the principles of robotics and the potential for low-cost manufacturing of autonomous systems. Background research indicates that obstacle avoidance robots rely heavily on sensor inputs and microcontroller-based decision-making algorithms, which inspired the design process.

Objectives

The primary objective was to develop a functional obstacle-avoidance robot utilizing Arduino UNO microcontroller, infrared sensors for obstacle detection, and a cardboard structure for the chassis. Specific goals included achieving reliable sensor readings, implementing effective navigation algorithms, and testing the robot in various obstacle configurations. The project hypothesized that a simple design with basic logic would suffice for obstacle avoidance in a typical indoor environment, which was validated through experiments.

Design, Analysis, Construction, and Verification

The core of this project centered on the design and assembly of a mobile robot that could autonomously navigate by avoiding obstacles. Figure 1 illustrates the overall system block diagram, comprising the Arduino microcontroller, IR sensors, motor drivers, and DC motors. The physical structure was constructed from cardboard, chosen for its lightweight and easy-to-cut properties, with motor mounts and sensor placements affixed securely for stability.

The circuit diagram (Figure 2) details the electrical connections. IR sensor outputs feed into Arduino digital input pins, which process signals to determine the presence of obstacles. The Arduino outputs PWM signals to the motor driver, controlling the direction and speed of the DC motors. The design analysis focused on sensor placement, motor control logic, and power management, ensuring sufficient sensitivity and response time.

Construction involved assembling the chassis from cardboard sheets, mounting the motors and sensors, wiring components according to the schematic, and writing the Arduino code to implement the obstacle detection and navigation logic. Verification involved multiple testing phases, wherein the robot was placed in environments with varying obstacle sizes and placements. Data collected indicated consistent obstacle detection and avoidance behavior, confirming the system's effectiveness. The flowchart in Figure 3 illustrates the main program logic, including sensor reading, decision-making, and motor control commands.

Discussion

The experimental results demonstrated that the obstacle-avoidance robot successfully navigated around obstacles within a limited space, confirming the effectiveness of the sensor and control system. The IR sensors provided reliable readings when obstacles were within a specified proximity (up to 15 cm). The robot's logic prioritized forward movement, with reactive turning maneuvers initiated upon obstacle detection, aligning with the expected behavior outlined in the initial hypotheses.

The use of cardboard as the chassis proved both cost-effective and practical, although it introduced some limitations in structural rigidity. Sensor placement on the front of the chassis was critical; misaligned sensors led to delayed responses or missed obstacles. The motor control logic was simple but sufficient for basic navigation tasks; more advanced algorithms could improve efficiency and obstacle handling capabilities.

Figures 4 and 5 showcase the robot in action and the corresponding sensor response graphs. The primary challenge encountered involved sensor interference and false positives at close range, indicating the need for filtering algorithms or additional sensors for enhanced precision. Additionally, power distribution issues occasionally caused inconsistent motor response, emphasizing the importance of stable power supplies in future iterations.

Plans for Next Semester

Building upon current progress, future plans include integrating ultrasonic sensors for more accurate distance measurement, developing more sophisticated navigation algorithms such as obstacle mapping and path planning, and constructing a more durable chassis from lightweight plastics. Additionally, incorporating wireless control or remote monitoring systems could enhance usability. Testing in more complex environments will help refine the robot's autonomy and robustness.

Conclusions

This project successfully demonstrated that a basic obstacle-avoidance robot could be assembled using simple materials and beginner-level electronics. The Arduino-based control system accurately interprets sensor inputs to execute reactive navigation, validating fundamental concepts in robotics. Despite certain limitations related to structural stability and sensor accuracy, the project fulfilled its objectives and provided valuable insights into embedded system design, sensor integration, and autonomous navigation strategies.

Recommendations

It is recommended to improve sensor accuracy by adding ultrasonic or combined sensor systems, use more durable materials for the chassis, and implement advanced algorithms like SLAM (Simultaneous Localization and Mapping) for complex navigation tasks. Additionally, optimizing power management and integrating user interfaces, such as remote controls or status displays, would enhance the robot's functionality and application scope.
