Voice Controlled Personal Assistant Robot for Elderly People

Personal assistant's robot helps to reduce the manual efforts of humans in their day-to-day tasks. This paper describes the design and development of a personal assistant robot, which is controlled by voice commands to pick long/short distance objects. Voice communication between the robot and android smartphone is done via Bluetooth. The proposed four-wheeled robot consists of a camera and robotic arm. The camera is used for object detection, distance measurement, and a robotic arm to perform pick and place actions. It can be widely used in many applications such as chemical industries, healthcare for the disabled and elderly population.
