Then I have to admit I was also uninformed of the state of the art of robotics: I had not heard or seen anything about the humanoid robot Asimo, which somebody finally mentioned in this thread as an outstanding contradiction of the claims of that book author (Stephen Gislason). I have to agree about Asimo: I looked up Asimo on YouTube and found some very impressive demos, especially of two-footed running, which impressed me the most—I didn’t know that was possible with the state of the art…

The grasping of objects such as trays and human hands also impressed me. Then I got to the videos that weren’t edited promotional materials and found the embarrassing failures of Asimo while in front of an audience…

I had to laugh at both of those disgraceful failures. The promoters sure didn’t know how to handle a failed demo, either: rather than dropping a curtain or putting up a privacy screen to hide their failure, they should have had a backup plan to provide humor, like to send in a couple guys dressed in white with a stretcher to cart the thing off, then maybe replace it with a miniature humanoid robot like Qbo or Nao…

I also noticed that the kitchen tray demonstration of Asimo was basically a laboratory set-up, with a pure white tray, pure white countertop, and clearly marked diagram on the counter where the tray was supposed to go. That means Gislason was largely correct…

So basically we’re still dealing with the laboratory microworlds / toy worlds of the early 1970s that David Marr described as having been a dead end per se…
The second approach was to try for depth of analysis by restricting the scope to a world of single, illuminated, matte white toy blocks set against a black background. The blocks could occur in any shapes provided only that all faces were planar and all edges were straight. This restriction allowed more specialized techniques to be used, but it still did not make the problem easy. The Binford-Horn line finder (Horn, 1973) was used to find edges, and both it and its sequel (described in Shirai, 1973) made use of the special circumstances of the environment, such as the fact that all edges there were straight.
These techniques did work reasonably well, however, and they allowed a preliminary analysis of later problems to emerge—roughly, what does one do once a complete line drawing has been extracted from a scene? Studies of this had begun sometime before with Roberts (1965) and Guzman (1968), and they culiminated in the works of Waltz (1975) and Mackworth (1973), which essentially solved the interpretation problem for line drawings derived from images of prismatic solids. Waltz’s work had a particularly dramatic impact, because it was the first to show explicitly that an exhaustive analysis of all possible physical arrangements of surfaces, edges, and shadows could lead to an effective and efficient algorithm for interpreting an actual image. Figure 1-3 and its legend convey the main
ideas behind Waltz’s theory.
The hope that lay behind this work was, of course, that once the toy world of white blocks had been understood, the solutions found there could be generalized, providing the basis for attacking the more complex problems posted by a richer visual environment. Unfortunately, this turned out not to be so. For the roots of the approach that was eventually successful, we have to look at the third kind of development that was taking place then.

So I believe Gislason wasn’t that far off.
Maybe somebody should post in this forum a summary of the state of the art in humanoid robots, something like the following?
