Carnival of Space No 167

Sometimes three isn't enough; let's add a Fourth Law of Robotics, how about

4. A robot shall visit the Carnival of Space every 604800 seconds and follow all the quality links contained therein as long as this does not conflict with the First, Second or Third Laws.

This week's Carnival is hosted by the spacetweepsociety, jump on over, there's lots to see and do!
