In his recent paper What Do Robots Dream Of, Dr. Adami, Professor of Applied Life Sciences at the Keck Graduate Institute, speculates that a robot might benefit from some "down time" just like people do.
Recent work in the study of dreaming indicates that more than just subconscious entertainment is going on. Sleep appears to help us work through and understand events of the day. Sleep also seems to provide a mechanism for impressing important memories on the brain, to make sure we have a long-term record of an event or concern. Sleep also seems to have a role in learning a skill; people who practiced a skill and then slept on it were more skillful than those who had not yet had a chance to sleep.
Dr. Adami speculates that if robots were given an alternate state, one in which the robot stopped exploring and instead focused on a problem or obstacle, it could provide benefits for them just like it provides benefits for human beings.
The robot's software designers could provide a robot with an internalized model of itself as well as the parameters of the situation. Then, the robot could explore different "dreamlike" situations, in which different parameters were distorted or exaggerated, until a solution could be found.
I can think of no more perfect place to start than with the "Starfish" robot created by Josh Bongard, Victor Zykov, and Hod Lipson of Cornell University. The Starfish robot is a new four-limbed robot that can automatically figure out where and how its body parts are connected, and then successfully move around.

Science fiction fans may remember SAL 9000, the artificial intelligence from the 1984 film 2010: The Year We Make Contact, taken from the book 2010: Odyssey Two (1982) by Arthur C. Clark. In the film version, SAL asks Dr. Chandra "Will I dream?" He replies "Of course you will. All intelligent beings dream. Nobody knows why... Perhaps you will dream about HAL - as I often do."
Another example of how sf writers have considered this idea is found in an Isaac Asimov short story from 1975, Point of View, in which a big computer named Multivac is having problems coming up with the right answers. A dad remarks to his son that Multivac is not a simple mechanical device (a machine) that would be easy to fix, nor is it as intelligent as a man, in which case you could ask what was wrong. His son remarks that maybe Multivac was like a kid:
