The chassis still looks great. Did you say that that was a local manufacturer? And I'm curious - did you end up just having to send them some sort of file exported from your designs in Sketchup?
I don't know if you've seen my latest posts on my recorder robot, but my next project ambition for application in future, similar robots is to design some sort of universal finger. I'm not exactly sure how I'm going to do that, but I know I'll eventually want a lot of them. For that reason I'm trying to find out how I might have them easily built (or parts made for my assembly) on a limited prototyping budget.
I wonder if you're interested in collaborating, even if just casually through this forum, on the design of a robot finger. It seems to me that it might be something marketable to your current and future enthusiasts - something that can simply, cheaply, and in a compact space quickly grip and carry an object. I know that if you already had them, I'd be buying them.
Sorry, didn't mean to hijack your thread - just thought it might be something of interest to you.
