Could a robot ride a skateboard
On Tue, 31 Aug 2010 09:19:31 -0500, Ignoramus20906
scribed: Yesterday, I was practicing with a skateboard and wondering about something. Do people know enough to program a computer, with a motion system attached to it, to ride a skateboard? This seems to be a far more difficult task than, say, a CNC metalworking machine. In the CNC application, all that matters is that the axes are moved precisely according to a pre-programmed sequence. In the skateboarding application, precision also matters, but it needs to react to the real time balancing situation. To somewhat simplify this, could a robot ride a skateboard on a surface that is well known to the robot (no need to recognize the surface from vision sensors). I was at a toy show in Rosemont last summer, and they had some enthusiast club show off "Linux robots". Those robots were physically fighting each other, in a very funny way. They looked like one year old kids as far as their ability to move and balance was concerned. i Check out this Big Dog... Pretty F'ing cool! http://www.youtube.com/watch?v=b2bExqhhWRI Fred III |

But OTOH, they are good for the military as long as they are fuel efficient i |
