You could probably buy 10 cheap webcams and put them all around the robot and get some vision algorithms to turn them into 3D scenes, which are avoided/mapped? This seems like a pretty well understood and constrained problem.
This kind of camera based system capable of producing good colour 3D models has just begun to become feasible within the last couple of years. At the moment lasers still remain fashionable amongst researchers since they are more accurate, which means that sensor modelling issues can be ignored for short distance ranging (say up to ten metres), hence the programmer has to do less work. The SLAM algorithms needed to be able to create good quality maps whilst also handling the uncertainty inherent in robot actuators and sensor readings have also been maturing in recent years, to the extent that it's now possible to do reasonable navigation within house sized or laboratory sized areas. ----- This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?member_id=231415&user_secret=fabd7936
