View Full Version : OT (sort of) odd question... anyone have info on the "Hexcrawler"?

A friend of mine dropped one off here, in reasonable condition and apparently complete, but with zip for info.

They seem to be discontinued, and the Parallax site search no longer finds it as a product, although a general site search gets an info page that they seem to have forgotten to get rid of.

It looks highly amusing, and offers some scope for machining parts and additions to it. (hence the 'sort of" OT).

I have no idea what you're talking about. :confused: Care to enlighten us?

Why yes that is an odd question - very odd question indeed....

This is probably the info page that JT referred to.

A video of what it looks like in motion.

And last but not least...a Yahoo user's group. Who would have guessed.

Thoses units went for about $600-$700 as a kit if I recall, don't bin it.;)

That's too bad. When it first came out and I saw it in Parallax magazine ads I thought they were reselling one of the lynxmotion products but now that its discontinued I went thru the whole lynxmotion lineup only to discover its very similar but not simply a rebadge.

If you're looking for leg kinematics eqns / software / hardware you could probably bodge some lynxmotion model AH2 stuff into working. I notice the lynxmotion product used hitec 422 servos and the parallax product used 322 servos, I don't understand the difference between those products because the torque is the same within only 10% or so and the speed is identical. Probably more research would uncover some minimal difference?

Actually, it appears that the thing actually came from a place known as "Crustcrawler", and they still had info and code examples, etc. So now I have something else to do after I finish the 25 years of "you need to do this soon" projects I have waiting for me.

"Bin it"? Nope.... if I get bored with it there is already another person who will happily take it.... he is a mentor for a robotics group, and familiar with a lot of these things.

It's a biggie....for those who were curious, here's a photo next to a yardstick. Had to find enough floor to set the thing down for the photo.
