What do robots dream of?

Reading a Perspective article in Science, or actually reading a Letter responding to the article, brought to my attention once again the research on robot cognition and self-awareness. How can robots be programmed to learn independently? And can they be modeled by our knowledge of human learning?
The article 'Resilient Machines Through Continuous Self-Modeling' describes how a robot can model its own gait, and if it is injured by i.e. removing part of a limb, it can think up new ways of walking by a dream-like process. In the 'dream' it revisits its past experiences and recombines the knowledge to try out new solutions to the problem.

Jeff Hawkins, the inventor of the Palm Pilot, is now working on a new computing concept related to Artificial Neural Networks. They call it HTM for Hierachical Temporal Memory, and it can be used to learn and model problems in a temporal setting.
Read his article introducin HTMs:
