Students learn about the similarities between the human brain and its engineering counterpart, the computer. Since students work with computers routinely, this comparison strengthens their understanding of both how the brain works and how it parallels that of a computer. Students are also introduced to the "stimulus-sensor-coordinator-effector-response" framework through the associated activity to reinforce their understanding of human and robot interactions.
Biological engineers and neuroscientists perceive the human body as a functioning, controlled system, similar to a robot. Research shows that electrical, mechanical and biological engineers may apply mathematical principles similar to those used in human brains and systems as they continue to devise better robots, computers and sensors. In this lesson, students compare the functionalities of human brains and robot computers, noting the similarities and differences. Engineers are learning how pressure sensors in the human fingers help you pick up a glass without breaking it, and use that information to design better touch sensors for robots. Engineers also examine how the human eye works so that they can design cameras with higher performance and speed.
After this lesson, students should be able to:
- Explain how the human brain is similar to a computer by providing at least one example.
- Describe how the motor cortex of the brain helps us with movement such as walking, and related that to how a robot computer helps a robot move forward.
- Explain how human senses and the brain interact to accomplish a task, and relate that to how an electronic sensor interacts with a robot to accomplish a task.
