Robot Navigation is a large component of current robotics research. In this paper, a method to implement the “go-to-goal” aspect of navigation is discussed. Specifically, I will first discuss a method called Egocentric Navigation, which was developed at Vanderbilt University’s Center for Intelligent Systems. Then improvements toward making the system more accurate and efficient will be proposed.

Memory is getting smaller and smaller by the month. Samsung has announced shipment of 8GB microcards that can be used in portable devices such as cellphones and even in external memory adapters for a huge boost in storage. The day will come when traditional portable HDs will be phased out in favor of the more versatile flash drives which you can use anywhere - since there are no moving parts.

A photoplotter is a printing device that exposes light to a photo sensitive film to produce output. The film is then developed like traditional photos to get the result. There are 2 types of photoplotter, vector type and raster type. Vector plotters move the exposure light anywhere in 2D space to create the image. Need a line from point A to B? No problem, just move from A to B. These are similar
