To Alice MacNare, just the presence of the animals in her husband's study brought the research project into reality. As the days passed that romantic feeling became fact.
"We're going to have to do together," Joe MacNare told her at the end of the first week, "what a team of a dozen specialists in separate fields should be doing. Our first job, before we can do anything else, is to study the natural movements of each species and translate them into patterns of robot directives."
"Robot directives?"
"I visualize it this way," Dr. MacNare said. "The animal will be strapped comfortably in a frame so that its body can't move but its legs can. Its legs will be attached to four separate, free-moving levers which make a different electrical contact for every position. Each electrical contact, or control switch, will cause the robot body to do one specific thing, such as move a leg, utter some particular sound through its voice box, or move just one finger. Can you visualize that, Alice?"
Alice nodded.
"Okay. Now, one leg has to be used for nothing but voice sounds. That leaves three legs for control of the movements of the robot body. In body movement there will be simultaneous movements and sequences. A simple sequence can be controlled by one leg. All movements of the robot will have to be reduced to not more than three concurrent sequences of movement of the animal's legs. Our problem, then, is to make the unlearned and the most natural movements of the legs of the animal control the robot body's movements in a functional manner."
Endless hours were consumed in this initial study and mapping. Alice worked at it while her husband was at the university and Paul was at school. Dr. MacNare rushed home each day to go over what she had done and continue the work himself.
He grew more and more grudging of the time his classes took. In December he finally wrote to the three technical journals that had been expecting papers from him for publication during the year that he would be too busy to do them.
By January the initial phase of research was well enough along so that Dr. MacNare could begin planning the robot. For this he set up a workshop in the garage.
