(...) Now, that's just flat out cool...and fun!!! (except for maybe...the cats.) I'm curious if soccer/foot balls and basketballs can work in place of Zamor spheres. Scott (16 years ago, 2-Mar-09, to lugnet.robotics)

OK, it was pointed out to me that I hadn't actually announced this on LUGNET, so... Ogre is the logical (or perhaps I should say "obsessive") conclusion to a series of Zamor shooting robots I've played with for a while. The launching system fires (...)

Thanks Brian (...) Your excellent graph shows that you tried to maintain the sound pressure constant. We did the inverse in the last graphs, where we tried to draw the curve for a constant NXT sensor value. We also repeated the experiment, and this (...)
