Abstract

Human-robot interaction (HRI), particularly in assistive robotics, has grown in importance in today’s robotics industry. A hand gesture controlled differential drive robot has been developed in order to allow for more natural interactions between humans and robots. Through physical changes like hand tilting, this system acts as a connection between the user and the differential drive robot. Instead of a joystick or other physical device with buttons, hand gestures are being used. Since a disabled person who is driving his wheelchair by hand is quite a lot of difficulty, a hand gesture controlled wheelchair is designed to allow a disabled person to move more freely by using only hand gestures without having to touch the wheels of the chairs. Thus, in this study, a scaled down hand gesture controlled wheelchair or smart wheelchair with the differential drive mobile robot is created as the prototype for this project to understand how the human-robot interaction (HRI) works by showing hand gestures only to control the smart wheelchair. The hand gesture controlled wheelchair typically consists of a sensor system, a controller, and an actuator. The sensor system captures the hand gestures made by the user, which are then processed by the controller. The controller interprets the signals and sends commands to the actuator, which controls the movement and direction of the wheelchair. The prototype will be designed with the assistance of a computer, software and after the mechanical and electronic components have been assembled, tests will be run to evaluate the prototype’s performance.
