This is the second part of a two-part paper describing the author's recent experiences with robot control systems. In part one, the three principal robotics language philosophies were illustrated. This was followed by a discussion of unconventional languages for robot control, namely PostScript and Java. In this installment, the author describes how he used(More)
This two-part paper describes the author's recent experiences with robot control systems. 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)
An unusual event occurred on February 12, 2001: a man-made satellite safely landed on the surface of a twenty-one mile long hunk of space rock two hundred million miles from Earth. It then sent pictures back home to the deleriously happy engineers who had shot it into space five years earlier [1 ]. Forty-eight hours shy of Valentine's Day, the NEAR(More)
This month's Forth Column carries a different message than the usual " Forth programming is great " homily. The Forth language has a bit part later in this play, as a work in progress. But the bulk of this essay is devoted to issues related to the manned exploration of space, a favorite topic for us Boomers who watched Armstrong and Aldrin tread the Sea of(More)
Human progress advances in many ways. One method obvious to all is to take something, a bicycle for instance, and make a multitude of small changes to the design over time. 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)
Biological phenomena are often modeled with software on digital computers, even though the events may be analog in nature. The author describes the use of linear circuitry in two areas of biological simulation: artificial neural networks and affective computing. The operational amplifier, with the assistance of some new analog chips and simple digital(More)
