The author discusses second generation robots. The second generation is attempting to overcome unawareness by equipping machines with senses and applying artificial intelligence techniques in order that the senses may be used in a human-like manner. The most critical element in robotics is the interface with the environment, both in sensing (input) and manipulating (output). Until recently the curent technology offered much on the output side but was lacking considerably on the input interface. Obviously the direction for research and development is in the application of sensors, the question therefore is how.
