Plenty of people have build eight legged walkers - that's not all that hard. However, the machine in WWW is supposedly very flexible and could climb near vertical cliff-faces, etc. You'd need at least two or three motors per leg to get that kind of flexibility. I'd suggest using one RCX per leg! Realistically, this would be very difficult. The issue of how the spider in WWW was controlled was of course quietly ignored...but that's not something you could avoid. Providing a remote controller to drive all those legs in useful ways would be an ergonomic nightmare...trying to make the robot sense it's environment well enough to climb over things would be a major technical challenge. I suggest you start off by looking at the Mibo project (Like the AIBO robotic dog - but done in Lego). ---------------------------- Steve Baker ------------------------- HomeEmail: <sjbaker1@airmail.net> WorkEmail: <sjbaker@link.com> HomePage : http://www.sjbaker.org Projects : http://plib.sf.net http://tuxaqfh.sf.net http://tuxkart.sf.net http://prettypoly.sf.net -----BEGIN GEEK CODE BLOCK----- GCS d-- s:+ a+ C++++$ UL+++$ P--- L++++$ E--- W+++ N o+ K? w--- !O M- V-- PS++ PE- Y-- PGP-- t+ 5 X R+++ tv b++ DI++ D G+ e++ h--(-) r+++ y++++ -----END GEEK CODE BLOCK-----

(...) That's one approach, probably the wrong one considering the limitations of the RCX. Instead of trying to solve your problems with the RCX why not take the approach of the original; pullies, gears, differentials, gear trains, etc. As I made (...) (21 years ago, 1-Dec-03, to lugnet.robotics)

(...) I'd recommend pneumatics instead of large number of RCX's. Kevin (21 years ago, 2-Dec-03, to lugnet.robotics)

Or, provide suggestions on how to do it? I saw Wild Wild West the other day and was looking at the giant spider robot and wondered if making such a "sipder" robot is possible with lego robotics? Would it be possible? Has anyone done it? Does anyone (...) (21 years ago, 1-Dec-03, to lugnet.robotics)
