Name: PullBack RCX Car Author: Øyvind Steinnes homepage: http://f0nix.i.am Lego: http://www.brickshelf.com/cgi-bin/gallery.cgi?m=Phoenix Description ----------- This is an atempt to build an "pullback car" that is powered by the RCX instead of an spring like a normal pullback motor. It works like this; when you start the program nothing happens. But when you then push it either forward or backwards (what is front or back on this car anyway?) and then release it, the RCX has recorded the amount of travel and direction when pushing and after a few seconds it starts to move the car back to its origin. I have not made the program yet. But it should be too complicated to make in Minstorm 2.0. I only have Mindstorm 1.5 installed at this point and it is not possible to record and store an variable in this program :( I do not know how to program in NQC or other programs like that. I leave that to you :) Regards Øyvind Steinnes
