The colour-based Autonomous File Extraction Rover

The Autonomous File Extraction Rover mobile robot, using NXT 2.0, is presented. A novel proposition is made that millions of file items can be uniquely searched, retrieved or sorted based on their unique colour when both the RGB and HSL colorspaces are used to widen the scope of the object recognition capability of the robotic system, through advanced colour identification devices. Object perception and identification using the NXT RGB colour system is used as a sample demonstration. The agent can search, retrieve and sort using a set of colour sensors, ultrasonic sensor, touch sensor, three servor motors and programmed using the interactive NXT-G programming language. This project involves with an extensive robot construction works with varied algorithms such as path planning, object detection and navigation. The agent is able to search, sort, grab and release items based on the instruction it has received in a highly-controlled environment but requires improvement when operational commercially.
