Pipe Inspection Robots

 

The Active Structures Laboratory built these amazing pipe inspection robots. The mechanism has a spinning wheel assembly that propels it through pipes. It even allows it to climb up pipes almost effortlessly. I wonder if someone can build something similar using Lego bricks. They have some really good videos of it on their website.
