Despite laboring in relatively obscurity most of his life, author Philip K. Dick has gained status in popular culture in the last 20 years. Among others, his novels or stories were the basis for a number of movies, including Blade Runner, Total Recall and Minority Report. The films raised questions common to Dick's body of work. What does it mean to be human? What is reality?
Blade Runner is based on Dick's novel Do Androids Dream of Electric Sheep? and is built around exceedingly human-like androids he calls "replicants." As a result, it should be no suprise then that one of the most human looking and intelligent real-life androids was named for him.
David F. Dufty uses a variety of Dick's ideas and stories to provide greater perspective in How to Build an Android: The True Story of Philip K. Dick's Robotic Resurrection, the story of the development — and inadvertent loss — of the android modeled on Dick. The effort was headed by Dallas-based sculptor/roboticist David Hanson and programmer Andrew Olney and others at the Institute for Intelligent Systems at the University of Massachusetts.
The obstacles were numerous, especially considering the plan was to model the android after Dick. Although Dufty begins the book with the loss of the android's head on a plane flight from Dallas to San Francisco, the bulk of the book looks at the obstacles and the efforts to overcome them.
From a hardware standpoint, robotic reproductions of human features and facial expressions were relatively crude. Although Hanson developed a product he called Frubber, which had a skin-like appearance, there is an immense range of human facial expressions. Trying to reproduce those realistically is a struggle in and of itself.
On the software end, although the Institute for Intelligent Systems had made leaps in its efforts to create an interactive computerized teacher, even that focused on one subject area. An android, however, needs to be able to engage in a wide range of dialogue, some of which might be entirely unexpected. To address that in part, Olney programmed in various interviews with and writings by Dick.
Yet both that and Hanson's design of the head raises yet another issue — copyright. Hanson met with Dick's family and obtained permission to use his likeness and materials on the project.
In detailing the steps of the process, Dufty, a postgraduate researcher at the University of Memphis during the time, provides insight for the layperson. This even includes an example of the scientific method, as he recounts Hanson's efforts in assessing the validity of a theory known as the "uncanny valley," a hypothesis that the more a machine is made to look human but remains imperfect, the more disturbing they would become to humans.
