According to the abstract released by the Intellectual Property India: "Design and Implementation of a Reflex-Based Safety Control System for an Autonomous Mobile Robot Abstract-Autonomous mobile robots must operate safely in environments where obstacles, power limitations, overheating, and mechanical faults can occur unexpectedly. In this study, a reflex-based embedded safety control system is designed and validated on an autonomous mobile robot platform. The proposed system is developed using an Arduino microcontroller and integrates ultrasonic sensors for obstacle detection, a voltage sensing circuit for battery monitoring, temperature sensors for thermal protection, and wheel motion sensing for fault detection. A vibration sensor is additionally integrated to detect physical impacts or collisions, enabling the robot to immediately stop and prevent further damage, and Bluetooth-based wireless communication is incorporated to allow manual control when autonomous motion is halted. The controller continuously monitors multi-sensor data and employs a priority-based reflex mechanism to override normal motion commands whenever unsafe operating conditions are detected. Safety actions such as stopping the robot, reducing speed, activating cooling mechanisms during overheating, and disabling motion are executed in real time without the need for complex computational algorithms or learning-based approaches. The system was implemented on a prototype robot and experimentally tested under obstacle presence, low battery voltage, overheating, wheel fault, and collision conditions. Experimental results validate that the proposed system enhances operational safety and reliability through rapid reflex responses to critical conditions. The proposed approach offers a low-cost and practical solution for improving operational safety and reliability in autonomous mobile robots. Key words- Autonomous mobile robot, reflex based safety control, multi-sensor system, Bluetooth communication, collision detection."
