Nowadays, many robots are being used in industries, homes, military appli- cations, disaster management, etc. worldwide. The advancements in robotics have made lives easier for humans in many aspects, and it provides a safer and more efficient. People’s concerns about secure and frictionless home delivery services have grown due to the present coronavirus scenario around the world. During the tremendous strain on healthcare and hygiene, we have proposed  a prototype robot that can be very useful in reducing the danger of infectious disease transmission in the product distribution system. Designing and devel- oping a low-cost autonomous four-wheel portable drive robot prototype that can safely transport packages to a designated location utilizing a Bluetooth module and mobile application have been shown. After the robot reaches at its point of disembarkation, it waits for the customer to unlock the container. The customer will get an otp as a password to open the container and retrieve the ordered product upon delivery. This password in the form of an otp is sent to the customer with the confirmation message from the order. After completing the delivery, the robot will arrive to point of disembarkation on its own. In addition to ensuring infection safe delivery of products, our robot can be an effective technological solution that significantly reduces delivery costs.

The review paper aims to outline the most significant accomplishments in Wire Arc Additive Manufacturing. It can capture the benefits of using the Additive Manufacturing method to manufacture layer-by-layer deposition at significantly reduced production values. Due to the viability of cautiously producing bulky metal components with comparatively high deposition rates, weighty progress has been complete in the thoughtful of the Wire Arc Additive Manufacturing process. Compared to ancient production, the use of this method has resulted in decreased Buy-To-Fly ratios of components the many applications such as saltwater valves, pumps, and turbine propellers, thereby aiding small-batch production. The input parameter is the travel speed, and the output deposition is layered large-scale metal elements with comparatively high deposition rates. The creation of cost-efficient prototypes as microstructure and mechanical properties, deformation, porosity, and cracking are also concerted in different alloy components.
