I have always thought hexapods were cool and that is
why I have been reading the Robofac articles as soon
as they come out. Hexapods are substancially more
complicated to get working than a orthoganal 3-axis
machine. It is really impressive when somebody builds
one from scratch and makes useful parts.

This is drifting off topic. I got mine on line in digital
format this past month. However, I personally do not like
the digital delivery technology that that the Servo staff
selected, so I will be switching back to the paper delivery
format in the coming months.
