Hope this isn't a re-post. I saw this about a year ago and something on telly last night jogged my memory. Its a masterpiece of Design, Engineering, Electronics and Programming. The bit when he kicks it is outstanding. Its a pity that its so loud, I guess they are using an onboard genny to supply the juice. Boston Dynamics Big Dog http://www.youtube.com/watch?v=cNZPRsrwumQ |

Are they available in FDE 
Kicking it & staying upright is one thing. Wading up & down century is another altogether   - Have seen it before , its cool, but kind of creepy Creepy... That's exactly what I thought. When the guy kicks it, it reacts in such an 'alive' way..... As one commentator put... "Rise of the machines".....

So what does it use, loads of piezo gyros? It seems to know where to put its legs to stabilise itself. [geek mode on] cant say for certain, as i say not seen this specific one, but i'd say from experiance a selection of gps, compasses, Laser gyros, tri-axel accelerometers and pressure sensors to detect attitude,speed, direction and sudden motion all inputed into a cpu to act and respond and keep the robot within specific parameters
