Robotic Item Retrieval System

The Robotic Item Retrieval System is a household robot that could self-navigate in a room and retrieve items for the user. The robot is running on a wheeled base and it is equipped with an elevator platform and robotic arms for item retrieval. The robot is equipped with a surveillance camera and ultrasonic sensors for navigation and item identification. A computer graphical interface is used to control the robot. The robot will be operating wirelessly through 802.11g/n wireless network to perform bi-directional communication with the host computer GUI. Aside from manual remote control, the robot will support two automated navigation methods: line following and map generation. The line following method requires pre-placed markers on the floor to guide the robot through the room. The map generation method is more sophisticated, as it enables the robot to generate its own room map and use it for navigation later. Due to the time constraint of this project, our functional prototype may only support line following navigation. However, the map generation navigation will be implemented for the final product.
