A drone is a type of machine that can be controlled remotely. A team of engineers designed a drone for taking pictures on the International Space Station, which orbits Earth. Scientists on Earth use the drone to take pictures of activities on the space station. The pictures are transmitted from the drone back to the scientists on Earth.
Which of the following would be classified as feedback? (sending the pictures from the drone, receiving the pictures from the drone, constructing the drone’s communication system, reporting problems about the drone’s control system)
Reporting problems about the drone’s control system
