Here is my behind the spider video.
All the mechanism for the legs are a simple cam see here: http://www.flying-pig.co.uk/mechanisms/pages/irregular.htmlAre there any close-up shots of the mechanism for the legs? I am not sure I understand exactly how it is hooked up and wasn't sure how the legs were attached.
Wiper motors operate on 12Volt DCWould this only require some hardware and a wiper motor wired to AC
No any more than if it was mounted horizontally the weight of the legs are being counter balanced by the bungee cordwould that create unacceptable strain on the motor since the apparatus would be at an angle and not horizontal?
You could wrap the wire in foam to bulk it up but I think the flexable tubing would weigh about the same as the pvcI was thinking that perhaps strong wire through flexible tubing might be lighter than PVC for the legs with "leg warmers" made of yarn unless someone has a lighter/simpler leg idea.
