Technologies of Today and Near Future
Many technologies share this theme of a Sense-Compute-Communicate-Actuate loop.
Sense
Sense
Use sensors to pick up signals - get information about the environment
Compute
Compute
Use computation using that information
Communicate
Communicate
Send results of computation (or some of the sensed information) to other systems or to humans
Actuate
Actuate
Take some action: physically move (with help of motors) or send a signal
Loop
Loop
Go through the four-step process again and again
