A. Feedback is the information a machine or program receives from a sensor that describes its current state. For example, in a thermostat, the temperature sensing part of the device would be the feedback portion of the device.
B. Control is using the feedback information adjust its current state to achieve a preferred state. For the thermostat example, the magnets adjusting to change the heater on or off based on its current temperature would be control function of the thermostat.
C. I was personally intrigued by how interdisciplinary feedback and control was between varying fields such as Engineering, Computer Science, and Mathematics. I originally thought that feedback and control were largely Engineering concepts since it dealt with senors and changing the state of the robot. However, especially with this current assignment concerning the SciBorg, I have begun to realize that there is a considerable overlap between Engineering and Computer Science. The fact that Mathematics is also an important field should not be so surprising as well since it is needed to compare the current state of the device to its ideal state. It makes sense as well that more complicated systems would require more extensive and complicated algorithms from all of these fields to complete.
D. After reading this article, I would like to learn more specifically about what innovations are needed for the next generation of feedback and control. The article mentions several times about how there is a need for more advanced and innovative technology, but it never went into depth into a certain case study of it.
