15 wall climbing robots

Robots often look insect like, largely because of their jerky movements and exo-skeletal look, both of which are a result of them often being works in progress at the individual and overall state of the art. Making them climb walls and hang effortlessly off a ceiling just adds them looking particularly bug like.

There are a variety of movements and gripping mechanisms, from electromagnetic to air suction, however our favorite is the friction based tree climber.
