Robots have become important today as they are capable of doing tasks that humans cannot do easily. This project deals with the concept of a firefighting robotic vehicle. The proposed project deals with the possibility of a firefighting mechanical vehicle that has different strategies for action. The mechanical vehicle can be controlled physically which can be utilized to stifle the fire utilizing a remote controller. We have included two modes of operation in manual control: remote control and voice control in voice control mode. The robotic vehicle can be controlled using voice commands so that the user can navigate the robotic vehicle with voice commands. The proposed project also implements a robotic arm to facilitate fire extinguishing at different heights. The vehicle is also equipped with a camera that can feed live video from the robotic vehicle wirelessly and help in navigation by visuals from the camera. The vehicle also implements autonomous mode which will automatically detect the fire using the sensors on the robotic vehicle, move to fire location and automatically extinguish the fire.

A muffler, a crucial component in vehicle exhaust systems, serves to mitigate and regulate the noise produced by the engine. It acts as a sound-controlling enclosure strategically designed with diverse shapes to reduce the intensity of sound waves travelling through the exhaust pipe. Consequently, prior evaluation of a muffler's efficiency before installation is imperative. Numerous factors, including the origin and dissipation of sound waves, influence the effectiveness of a muffler. However, the precise engineering design of the muffler itself remains the primary determinant of an exhaust system's efficacy in any vehicle. Assessing the acoustic performance of a muffler often revolves around metrics like Transmission Loss (TL). The Transfer Matrix Method (TMM), a prevalent mathematical technique, proves particularly useful when analyzing systems comprised of multiple subsystems or varying geometries interacting within the overall setup. In the case of a muffler, each subsystem represents acoustic impedance, and their collective interaction defines the system's noise reduction or transmission loss. This study endeavours to explore how different types of mufflers impact Transmission Loss using TMM and aims to elucidate the influence of diverse design configurations on this crucial acoustic metric.

Modern technology like the Advanced Driver Assistance System (ADAS) is designed to improve vehicle safety and collision avoidance. Three essential parts are integrated into this system: an automated braking system, a pneumatic bumper, and a 360-degree steering mechanism with its 360-degree steering system, the car can steer in any direction, making manoeuvring through narrow spaces easier and lowering the chance of a collision. In collisions, the pneumatic bumper reduces damage to the car and occupant injuries by cushioning impacts with compressed air. In the meantime, the automated braking system reduces the possibility of accidents brought on by human error by using sophisticated sensors and algorithms to identify approaching collisions and automatically apply the brakes. The integrated ADAS system seeks to increase driver safety, lessen the frequency and severity of traffic accidents, and boost the effectiveness of road transportation as a whole by integrating these features. This cutting-edge technology demonstrates a dedication to raising vehicle safety standards and marks a substantial advancement in automotive safety.

By incorporating features that facilitate easy conversion between wheelchair and stretcher modes, this innovative solution aims to enhance efficiency and convenience in hospital environments. Furthermore, the manufacturing process involved in bringing this multi-purpose wheelchair mechanism to fruition is meticulously outlined, encompassing the selection of materials, fabrication techniques, and quality control measures. Emphasis is placed on achieving a balance between durability, manoeuvrability, and cost-effectiveness to ensure widespread adoption and practicality within healthcare institutions. Overall, the multi-purpose wheelchair mechanism presented in this paper represents a significant advancement in patient mobility solutions, offering a versatile and user-friendly option for hospital use. By addressing the spatial constraints, labour intensity, and patient discomfort associated with traditional patient transport methods, this innovation stands to greatly benefit both healthcare workers and patients, contributing to improved efficiency and quality of care within medical facilities.

Analyzing the Failure of a Truck's Rear Axle Shaft Requires a Thorough Investigation to Pinpoint the Root Cause of the Issue

The analysis of a failed rear axle shaft from a dumper truck involved a comprehensive investigation to ascertain the underlying cause of the failure. Visual inspection, material analysis, mechanical testing, and fracture analysis were conducted to assess the condition of the axle shaft. The axle shaft exhibited signs of fatigue failure, with the fracture surface showing fatigue striations. Microstructural analysis revealed a coarse grain structure with inclusions, indicating potential material defects. Tensile testing showed that the axle shaft had lower-than-expected mechanical properties, suggesting a possible issue with material quality or heat treatment. Based on the analysis, the root cause of the failure was determined to be a combination of material defects and fatigue loading. Types of investigation like as visual examination, chemical analysis, hardness test, tensile test, fractography and ultrasonic test, and microstructure examination. Microstructure observation of the sample indicates a normal ferrite–pearlite (lower critical point) sorbite-type structure with some spheronization seen on some portions Results indicate that the failure occurred due to a sudden load on the axle shaft, specifically at its weakest point. The shear stresses on the axle shaft were insufficient to withstand the stresses caused by the sudden loading. Based on the analysis, make recommendations for corrective actions to prevent similar failures in the future. This may include design improvements, material changes, maintenance procedures, or operational changes. This may include design improvement, material changes, maintenance procedures, and operational changes. Implement the recommended corrective actions to prevent similar failures in other axle shafts or similar components.
