Ramacorp.org - Homebrew robotics and inventions, and other interesting things. http://www.ramacorp.org Sun, 08 Jun 2008 18:21:32 GMT If you find yourself bored at home (or at work...) and would like to help out the astronomy community, you can spend an hour helping classify galaxies. The kicker for them is that with all of our technology, they still don't have classification software reliable enough to correctly classify galaxies into 1 of 6 bins: spiral (clockwise from our view), spiral (counterclockwise from our view) spiral (edge-on), elliptical, merging galaxies, or unsure. They maintain robustness in having us classify their galaxies just by the reliability in shear number of users. Their website is http://www.galaxyzoo.org http://www.ramacorp.org/galaxy_zoo.php http://www.ramacorp.org/galaxy_zoo.php Virginia Tech's entry into the 2007 DARPA Urban Challenge is named Odin, and they are called Team Victor Tango . It's a hybrid Ford Escape, and drives very well. They took their vehicle to the Caterpillar campus in Peoria, IL for a public demo. http://www.ramacorp.org/victor_tango_darpa_urban_challenge.php http://www.ramacorp.org/victor_tango_darpa_urban_challenge.php http://www.ramacorp.org/hydroforming_metal.php http://www.ramacorp.org/hydroforming_metal.php This is a good overview of different prototyping techniques such as: StereoLithography (SLA), Powder Fused Modeling, Machining a mold, Creating a negative sand (with binding agent) mold + using the mold to cast a part, Creating a plaster negative mold + and using mold to cast a part Rapid Tooling And Prototyping How Its Made - For more amazing video clips, click here http://www.ramacorp.org/different_prototyping_and_manufacturing_methods.php http://www.ramacorp.org/different_prototyping_and_manufacturing_methods.php FDM (Fused Deposition Modeling) from Printo3d FDM from Dimension BST 3D FDM from Fab@home - a squeeze bulb FDM from Fab@home - a watchband http://www.ramacorp.org/fused_deposition_modeling.php http://www.ramacorp.org/fused_deposition_modeling.php Objet's Polyjet Modeling Machine http://www.ramacorp.org/polyjet_modeling.php http://www.ramacorp.org/polyjet_modeling.php
