A wall climbing robot with a difference. ROCR is designed to use a pendalum effect to climb walls. Swinging as a human does from toe hold to toe hold using its tail as a balance and a lever.
It can only climb carpeted walls at the moment but plans are afoot to make it climb brick or sandstone which should be easy enough. Let’s see how well it does on marble or glass though. It will need other feet for those.
The long term intention is to built a unit to make a tool for inspection, maintenance and surveillance. Personally, I can’t see it being useful for inspectiion and maintenance as it clearly will be for surveillance. I can envisage smaller versions of this loaded with micro cameras and climbing any surface to spy on people. Every spy will have a few of these in their toolkit

It can only climb carpeted walls
Ah well – there are plenty of those.
I have actually seem office buildings with walls that are like carpet but never real carpet. Maybe I don’t get out much.
