The paper describes the design, construction, and the programming process for a small-scale mobile robot, which can monitor and report a house’s condition while the host is away from home. This system is one example of several that have been built by K-12 or undergraduate students learning about robotic system design. The hardware is based on LEGO Mindstorms Kit, which is powered by 6 AA batteries. The development software CD comes with the LEGO kit, and can also be downloaded from LEGO’s official website. Since the system was constructed by using plastic blocks of LEGO components, so no machining or parts fabrication was required. During this project, students would learn how to build the required robot platform according to the instruction and how to make connection between sensors/motor or interface I/O devices with the micro-controller (NXT) which is the core and brain of entire robotic system. Students also learn the programming logics in order to make robot perform the required task. The software tool is an icon-based proprietary programming language, NXT-G, developed by LEGO and/or its affiliated organization. This easy to use programming tool is drag and drop from icon palette, almost no coding required. It saves students a lot of debugging time for syntax errors or other trivial linking and compiling seen in generic programming languages. Because it is GUI-based, it is very easy for beginner to trouble-shoot and fix the programs to suit the new tasks. This unit does not end here. Students should augment this project and develop their own robotic projects with additional function or task based on this model.
