question 4 of 10
which three decisions might a robot vacuum cleaner make once it is powered
on and is at the \follow route\ stage?

a. is the route finished?

b. unplug from wall?

c. is the battery low?

d. is the vacuum full?

Explanation:

To determine the three decisions a robot vacuum in "Follow route" stage might make:

• Option A: Checking if the route is finished is relevant to route - following, as it decides if the cleaning task along the route is done.
• Option C: Checking battery level is important to know if it can continue following the route or needs to recharge.
• Option D: Checking if the vacuum is full is relevant to know if it can continue cleaning along the route or needs to empty.
• Option B is not relevant as unplugging from the wall is not a decision made during the "Follow route" stage (it's more related to initial setup or charging).

Answer:

A. Is the route finished?, C. Is the battery low?, D. Is the vacuum full?
