First, three principal programming techniques are reviewed, including dedicated robotics languages; machine tool languages; and general purpose computer programming languages. Then, unconventional languages for robot control, such as PostScript and Java, are discussed.(More)

Each iteration of the refinement process gives us something newer and nicer to appreciate. That's how you start out with a $50 Schwinn bike and end up with a $10,000 Lotus racing(More)
