Treads and other details - kresty - 10-18-2017
Paul6700 thinks that the Treadwell tracks are a 140T 1/2" pitch 70"x3" blower/supercharger belt (like this one, however long this link might last) - he posted a grainy photo, so I tried tracking it down and discovered an early droid electronics magazine article, how cool!
Anyway, the article included this cool image with lots of Treadwell parts:

Treadwell from Electronics Today International, Dec 1977
Decent detail shots of the WED Treadwell (stick droid)
- The tread can be seen, along with a guide track (Paul6700 used an old fan belt chopped up and attached to the blower belt.
- A bit of the detail of a drive wheel as well (did the sand get in all those cracks?)
- A close up of the head - I know we've had some of that before.
- An arm detail, I don't think there are many great arm pix
- The innards. Nothing surprising there, motors & batteries mostly, but interesting nevertheless. Flexible couplings on the driveshafts are interesting (to me).
