Here's next week's video, early for Patrons. This one goes out publicly on Tuesday 14th September.

When I previously did the video about the Rotaped tracks, it got posted on Hackaday. Some people in the Hackaday article comments posted links about other weird wheel arrangements and one of them was the Pedrail. I couldn't find any video or pictures of this one in practical use (unless it has another name) so I thought I'd have a go at building one.

Pedrail - PREVIEW VERSION

I've previously experimented with a number of innovate wheel designs including ball-shaped-omni-wheels, Rotaped Tracks, and various balancing robots. I came across this Pedrail concept which has lots of compliant feet around its circumference, and I wanted to see how practical it would be for climbing over objects and up steps.

Did you consider replacing those feet with suction cups so it can climb walls? Just looks like a natural climber ;-P

It would be good to see some footage of how differently it performs with rubber stoppers on the feet.

I think itcwould need something to push the legs down because it couldn't rely on gravity then. Also something to swivel the ankles. Possibly could work.

I thought it would probably just grip on everything then so it wouldn't really test the mechanism. A lot of people will probably suggest this though so I may revisit it, probably with four wheels.

yeah it does seem a bit unfair, but I think if you were to try and use this wheel system on a project you'd want it to be as effective as possible
