Reading science fiction is exciting for two reasons. Firstly, the stories about the future describe the kind of world the authors can imagine for tomorrow. They often take up the desires and longings of people in the present and show us what could become of them in a future in which completely different technical possibilities already exist.
On the other hand, the genre has now partly caught up with itself. Many stories that are considered classics today describe our present time. Stan Kubrick's classic ‘2001: A Space Odyssey’, for example, was released in 1968 and describes the year 2001 that gives the film its title. Isaac Asimov published his first robot story as early as 1940, thereby popularising a topic that is still being discussed today: humanoid robots. This refers to machines that resemble humans as closely as possible in terms of shape and behaviour.
The biggest challenges for humanoids
The technological development of humanoid robots has long since become a reality. The greatest challenges lie in the motor and cognitive abilities that are among the outstanding characteristics of humans. The ability to walk upright on two legs alone was a major hurdle for humanoid robots for a long time. A major leap was made in 2015 with the ‘walking robot’ ATRIAS, whose developers were even more strongly oriented towards the human mechanics of walking.
The biggest challenge here is that the human upright gait is not a stable system, but rather a series of falls from one step into the next. On level ground, this can still be easily calculated mathematically for robots, but in everyday life there are hardly any such strictly defined situations. However, uneven surfaces are no longer a problem for ATRIAS, developed at Oregon State University (link to video).
Approaching communicative abilities is at least as important as the complex development of motor skills. Here, the differences between humanoids and their human role models were even greater for a long time. Automated speech output could hardly keep up with human complexity and did not appear fluid enough. The quality of content lagged even further behind. With the further development of the audio functionality of large language models, robots can now largely compensate for this shortcoming.
