- This is not a flame, but a reference to a really neat small six legged
- robot.

- In this article there is a picture of Genghis, a six legged
- robot and the caption reads:
-
- "Genghis is a six-legged robot measuring 35 centimeters in
- length. Each rigid leg is attached at a shoulder joint with
- two degrees of rotational freedom, each driven by a model
- airplane position controllable servo motor. The sensors
- are pitch and roll inclinometers, two collision-sensitive
- antennae, six forward-looking passive pyroelectric infrared
- sensors, and a crude force measurements from the servo loops
- of each motor. There are four onboard eight-bit
- microprocessors, three of which handle motor and sensor signals
- and one which runs the subsumption architecture."
-
- There are many references in the article, some of which are specific
- to Genghis.
-
- Almost certainly, Genghis is not an ``inexpensive'' or ``stripped down''
- robot, but it is impressive.
-
- If I remember correctly, there is also a group at Case Western Univ. (
- led by a Dr. Sterling? ) that has created a neural net that runs a six
- legged cockroach.
-
- Perhaps the six legged insect approach should be placed in the FAQ?
