Scott "Bucky" Cole, BSEE OSU 2001, successfully defended his Master's thesis in Electrical Engineering on February 4, 2005. Bucky is employed as an engineer with The Charles Machine Works in Perry, OK. His work involves the use of magnetic fields to guide underground excavating equipment. In order to better understand magnetic fields and their applications he chose, as a thesis topic, to design and build a system consisting of a wand and a mobile platform. The wand generates a fixed frequency magnetic field and the mobile platform, a wheeled robot, moves to where the wand is pointed. The robot accomplishes this by using on board sensors to determine its location in the magnetic field and moves to position itself in line with the wand's axis. The entire system was constructed from scratch using commercially available components. All circuitry was built using surface mount technology on custom designed printed circuit boards.
