The work summarized in this thesis focuses on the recording and analysis of data from micro-ECoG arrays implanted in vivo. The electrode arrays with diameters on the order of tens of microns and grid pitches on the order of hundreds of microns are recording from the surface of the brain at a novel scale. The research summarized in this work is aimed at the successful implantation and recording of these arrays and subsequent analysis of the properties of the electric potentials on the brain surface as measured at this considerably smaller than usual scale.

This thesis presents the results from a modification of a previously existing research project titled the Intelligent Pothole Repair Vehicle (IPRV). The direction of the research in this thesis was changed toward the development of an industrially based mobile robot. The principal goal of this work was the demonstration of the Precision Mechatronics Lab (PML) robot. This robot should be capable of traversing any known distance while maintaining a minimal position error. An optical correction capability has been added with the addition of a webcam and the appropriate image processing software. The primary development goal was the ability to maintain the accuracy and performance of the robot with inexpensive and low-resolution hardware. Combining the two abilities of dead-reckoning and optical correction on a single platform will yield a robot with the ability to accurately travel any distance. As shown in this thesis, the additional capability of off-loading its visual processing tasks to a remote computer allows the PML robot to be developed with less expensive hardware. The majority of the literature research presented in this paper is in the area of visual processing. Various methods used in industry to accomplish robotic mobility, optical processing, image enhancement, and target interception have been presented. This background material is important in understanding the complexity of this field of research and the potential application of the work conducted in this thesis. The methods shown in this research can be extended to other small robotic vehicles, with two separate drive wheels. An empirical method based upon system identification was used to develop the motion controllers. This research demonstrates a successful combination of a dead-reckoning capability, an optical correction method, and a simplified controller methodology capable of accurate path following. Implementation of this procedure could be extended to multiple and inexpensive robots used in a manufacturing setting.

Janet was friendless until Lola, a smelly. brutish and disheveled new schoolmate, shows up in class. Invited to spend the night at her new-found friend''s house, Janet accepts despite the curious and spooky rendezvous point -- Bent-Back Bridge. Oddly enough, Janet hasn''t been seen since!

Things were tough at times for Twofold Castle''s newest page, but Roland never expected to be this cold, hungry or wet. Mind you, Roland never expected to be this lost either. He was supposed to be with Morris, Humphrey and the other pages on a Royal hunting trip. Instead Roland and his pet mouse Nudge were lost in a thick, dark and terrifying forest. Why didn''t anyone explain how easy it is to become separated from the main party when the chase is on? And what does a small boy and a mouse do when the only possible rescuer is the last person either of you wants to see?

In the ''After Dark'' series'' for 10 to 14 year olds. Hiro, a lonely and artistic Japanese boy comes to live on Thursday Island. Local bullies force him to take part in their war games, but how can Hiro defend himself when his only weapons are a paintbrush and paper? The author''s other publications include ''Strange Objects'' and ''Mama''s Babies''.

Where did the curious, saucer-shaped clouds appear from? Why had the mystical depressions formed in the wheat fields? How could a wheat crop be ready to harvest in a matter of days? And most of all for Micah, what would be the outcome. After all he had disobeyed. Suggested level: primary, intermediate.
