Abstract
The Raspberry Pi serves as the central processor for this project. The main goal of achieving automated movement is accomplished through various interfaces. The first type of interface is a touchscreen that displays arrow keys, enabling the user to move in any desired direction. Additionally, the wheelchair can be controlled using Hand gestures, Voice commands, or an android phone. The wheelchair circuit includes an RF and Bluetooth receiver, which receives these commands and operates the wheelchair motors accordingly to achieve the desired movement. This system allows disabled individuals to easily operate the wheelchair, while also enabling another person to control it from a distance of 3-4 meters. By incorporating automation and safety features, the Raspberry Pi-based wheelchair safety system takes the wheelchair system to a new level.
