Abstract

 Steel plates are widely used in structural applications because of their ability to maintain structural form and their high tensile strength, which allows them to withstand significant loads in construction. This study presents the development of a monitoring system designed to measure strain in steel plate structures using strain gauge sensors. A theoretical comparison based on the elastic modulus of steel plates was employed to calculate stress, strain, and elongation under varying loads. The strain values recorded by the sensors are processed through an ESP32 microcontroller and displayed on an LCD screen for real-time observation. To enhance safety, the system is equipped with a buzzer and indicator lights that provide early warnings when the applied load exceeds a specified threshold. Experimental results show an average measurement error of only 2,98% compared to theoretical values, confirming the system’s accuracy and reliability. The proposed system offers a cost-effective and practical solution for infrastructure maintenance and supports the early detection of structural strain in steel plates.

Abstract

A micromouse robot is an autonomous robot designed to navigate mazes and find the shortest path to a destination point. This research aims to design a micromouse robot software system using a flood-fill algorithm that can move without touching the walls and determine the direction and angle of rotation when encountering a dead end. The system uses an Arduino Nano as a microcontroller, infrared sensors for wall detection, DC motors with rotary encoders, and a 2-channel motor driver, with a maximum robot dimension of 16.8 cm × 16.8 cm. The software implementation uses a Breadth-First Search (BFS)-based flood-fill algorithm for optimal path mapping, a 6-state state machine to regulate execution flow, Proportional-Derivative (PD) control with parameters Kp = 2.0 and Kd = 0.05 for movement stability, and trapezoidal velocity profiling for smooth movement. Test results show that the robot can complete a 4×4 maze in an average of 45 seconds, with position accuracy of ±5 mm and an angle deviation of less than 2 degrees. The PD control system provides a responsiveness of 32 ms, and velocity profiling reduces wheel slip by up to 90% and increases energy efficiency by 25%. This research contributes to the development of mobile robot technology and robotics learning media.
