Abstract
The aim of his project is to develop a single unit concept and design of a high maneuverability mobile robot to assists human beings in hazardous tasks. Robots that can climb walls can complete work in unsafe places where people might find them risky or inaccessible. They are able to work in challenging environments like high altitudes, cramped quarters, or places where chemicals, radiation, or extremely hot or cold circumstances could pose a risk. The risk to human workers is greatly decreased by utilising a wall-climbing robot. The robot's ability to maneuver through a dangerous environment and carry out activities without putting people in danger reduces the likelihood of mishaps, injuries, or exposure to poisonous materials. This magnet embedded wall-climbing robot is able climb vertical surfaces like metal buildings, ceilings, or walls. This makes it possible for it to reach places that are difficult or hazardous for humans to access, such as heights. It offers human employees who would normally need to use ladders, scaffolding, or harnesses a safer alternative. Furthermore, the robot can firmly cling to surfaces thanks to the high magnetic force, which also
ensures its attachment even in risky or unstable conditions. This stability reduces the possibility of the robot falling or slipping, which is essential when working in high or risky places. This design is able to solve the existing limitations of wall-climbing robot. A solid model drawing has been created using SolidWorks software and control system were done by using Arduino IDE software and Blynk app. Then, the prototype was fabricated using 3D printing and also cutting process. The hardware that have been used to connect the robot are NODEMCU ESP32 board, L298N motor driver and DC motors. After building the prototype the experimental studies and testing on the prototype were carried out. The final phase of the project was the application of the prototype on the real surface of the environment which is metal or iron board which acts as the wall. The robot was activated with the Wi-Fi. The prototype of the wall climbing robot was able to move in vertical direction of the wall with the magnetic adhesion from Neodymium magnet that has been attached with passive attachment.
