For a person who lost their arm or an upper limb, even a simple task becomes cumbersome because of their disability. Prosthetics play an important role in helping these people cope up with the challenges they face. Swift developments in technology have resulted in powered myoelectric hand prosthetics entering the market but are avoided by many for being expensive to purchase and maintain. This paper outlines the development of an economical prosthetic claw that can be controlled by muscle signals. The project primarily aims to bridge the gap between cheap non-functional prosthetics and expensive fully controllable prosthetics by being affordable, durable, and easy to manufacture without sacrificing functionality. The claw and its components have been designed to be easy to modify, repair, and replace, making it a flexible platform for customization as per the user’s need. This translates to an efficient and feasible solution to the ever-growing need for affordable functional upper limb prosthetics for the physically challenged.

Battery swapping is a popular alternative to the conventional battery charging, which involves removing a drained EV battery and replacing it with a fully charged one. EV users can swap batteries on the go at any battery charging station. A robust data management system facilitates this exchange by providing an interface and platform to locate new batteries. Using data analytics to quantify the voltage and temperature of the battery, the health of the battery is estimated and is displayed to the user. In comparison to the conventional charging procedure at a battery station, which can take hours, this service is less time consuming and easy to adopt in urban environments. This paper describes an IoT based real time monitoring system for these swappable batteries that enables customers to search for nearby battery swapping stations, while also transmitting each station's battery SOC and health. The system also communicates the station's operational status as well the health of the batteries to the manager of the station, easing the arduous task of monitoring them manually.
