(I've also posted this to the Seattle and RSSC lists, so my apologies if you get it more than once!)
I'd like to try building a Keepon:
I'm looking for ideas for the body design, esp. in terms of motion.
It looks like there are 4 motion primitives:
- vertical up and down
- pan
- tilt
- side-to-side rocking
Have I missed any?
My mechanical skills and equipment are limited (to say the least :) so ideally, I'd like to use something like the Lynxmotion servo erector set for this -- something I can essentially bolt together. Does anyone have experience using these? Do you think that's a feasible approach (precise enough, compact enough)?
Looking at their parts, I think I can see how everything except bobbing up and down can be accomplished. I'm a little stumped on that one! The two things that comes to mind are 1) a piston, cylinder, crankshaft assembly, which seems way too elaborate, or 2) some sort of cable and tube arrangement. But, I don't see parts for building a cable-based mechanism in the erector set. Did I just miss that?
Thanks for any ideas or suggestions you might have on this! Robin
