A very worthwhile-to-visit website is the one of the US National Aeronautics and Space Administration NASA. Here one can e.g. surf to the remarkable ANTS<\/a> – Autonomous NanoTechnology Swarm webpage (also autonomous in terms of graphic design…). I didn’t download the ANTS VRML<\/a> TetWalkerControl plugin, but rather tried to built my own tetrahedron walker with springs world 3D<\/a> – a 3D version of the famous sodaconstructor<\/a> (which had an update lately). Springs world 3D is a processing<\/a> applet by italian math and physics teacher Marcello Falco. <\/p>\n My little tetrahedron<\/a> walker (see above image) took a few minutes to build and of course it didn’t move as elegantly as the NASA one (probably mainly because I did no finetuning of the phases – I am anyway not sure wether the NASA model has a fixed phase relation (the video-tetwalker has stearable contraction as it seems)). However the processing main loop made my computer swap, which finished all activity :(. <\/p>\n There is also a forum of the 3D springs world over at soda constructor\/sodarace in particular a thread about dainty walkers<\/a>. Looks as may be Marcello Falco and the soda crew join forces :). ?.<\/p>\n
\nOn this page there is a lot to discover and especially the videos on the site breath the air of scientific exitement. In particular I liked the page with the NASA dainty walkers<\/a>, like e.g. the tetwalkers, but Lara – the movie –<\/a> is also definitely supercalifragilisticexpialidocious<\/a>. <\/p>\n
