Written by William Swansen on February 15th, 2022
Answer Example
"Humans interact with robots through a variety of means. These can include the programs which control robots, like the ones I write, and actively interact with them through speech, motion, and other types of inputs. As more sophisticated robots are being developed, the nature of human-robot interaction is also becoming more complex. Another aspect of human-robot interaction is on the emotional level.
Many humans fear robots or are anxious about how robots are gaining a more prominent position in human society. Some people are reluctant to interact with robots or are unfamiliar with how to do this. Others resent robots because they're taking over jobs previously performed by humans in industries including autos, drug manufacturing, customer service, and many others. The interaction between humans and robots will be a key area of debate and study for many years going forward."
