What does polling mean?

Checking repeatedly, in a loop, whether something has happened, such as whether a message has arrived, rather than being interrupted when it does.

Also written as: poll, polls

In a lesson

Now each tick is printed within a tenth of a second of being sent. This shape, check, act, wait, is called polling, and it is how every robot in this module listens. The wait matters: without it the loop asks thousands of times a second and the robot has no time for anything else.
