Hi Chemical,<br /><br />The simple answer is 'no'.<br /><br />Here's the long answer:<br /><br />To walk on uneven surfaces, walking animals have evolved a pretty complex corrective reflex system.<br />Because we animals continously correct our walk and stand subconsciously, it's easy to overlook at how complicated it is to do so.<br /><br />You can read up about it by googling something like: robot control walking animal<br />Here's <a href="http://www.rgu.ac.uk/eng/compint/page.cfm?pge=3842" class="postlink">an example</a> of a research group that's working on the subject.<br /><br />Also, for an interesting approach to the problem of dealing with walking over rough terrain, check out Alejandro Alonso-Puig's <a href="http://www.mundobot.com/projects/melanie/v3/enmelanie3.htm" class="postlink">Melanie-II</a> site.<br /><br />So KHR-1 as it comes unmodded and with standard software, won't like carpets or any unsmooth terrain. If you plug in a couple of gyros, you will get better results.<br />However, Kondo's ICS servos that come with the KHR-1, in theory could provide the foundation for feedback control (that would in turn allow for rough terrain walking). With every PWM cycle, the servos provide a reading of the current position. To utilize this feedback, a new controler has to be developed because the RCB-1 controler wasn't designed with feedback control in mind..<p>Statistics: Posted by <a href="http://forum.robosavvy.com/memberlist.php?mode=viewprofile&amp;u=2">limor</a> — Sat Mar 18, 2006 3:14 pm</p><hr />

Hey<br /><br /><br />I've never seen this mentioned, and all video's are on smooth surfaces, so i wanted to know how is the little guy on carpet?<br /><br /><br />Thanks<p>Statistics: Posted by <a href="http://forum.robosavvy.com/memberlist.php?mode=viewprofile&amp;u=104">Chemical</a> — Sat Mar 18, 2006 3:23 am</p><hr />
