What would you consider to be a small machine? Something 6 feet long and 3 feet high is not very small. If it was any smaller I don't think it would be very useful, it would have a hard time climbing over rocks and sand. Most of the room would be taken up with drive mechanics and computer hardware. This is if you consider it to be a stand alone machine. A good idea would be to use robots that act as long range sensors for the large robot. They would attach to the underside of the large robot, it would pick them up and store them. They would only have to be about 2 feet long and would be in constant contact, by radio, with the large machine. So they don't just wander away. If the large robot saw an object with it's camera, which would be about 12 feet in the air I presume. It could dispatch a small droid to investigate and relay pictures or get a sample of the object. This way the large robot could stay on it's course without running here and there and getting into possible danger. I think every machine has it's place. -pk -- ___________________________________________________ Patrick Kenny pkenny@ads.com | Purpose: To DownLoad and at Advanced Decision Systems 1500 Plymouth Street | last be free of the confines Mountain View, CA 94043 | of a shelled body.
