Nearly impossible without a huge processing center equivalent to the brain and centuries of learning to get it working right as with Homo Sapiens.. All the inputs we have like heat, light, dark, odors senses,radiation, sight, pressure, temperature, temperature change( a cold draft) internal temperature, a pain, a headache , colors have all been fine-tuned though the milleniums to find a correct survivable response. And learning to control the environment through fire, clothes, weapons, water containers, meat preservation - hunting, fishing, running, weapons. And finally the ability to communicate with other machines( people) and can tell them what infinite varieties of ways or actions they will have to take to survive. We have enough work to do surviving wars, radiation, floods, earthquakes,diseases, tax assessors, fires and weird actions of men like OBL and Saddam. Rule No1. Never program a robot for survivability as humans are programmed. He is liable to take over and find no use for us mortals. Rule No.2 If programming a device for self-replication, make damn sure you have three or more ways to stop the replication process. Rule 3. If two robots start changing colors , making strange noises, and dancing make certain it is not a mating ritual which may produce hordes of uncontrollable juvenile robots . Never forget what can go wrong, will go wrong. Sig
