When it comes to large buildings, we need some bots that can scale them and do maintenance. This bot does windows and walls, and any other flat surface a human can’t reach. The Snail by Yasunori Goto, Ibe Tommokichi and Hirata Ichiro, climbs and sticks to surfaces using air compression suction.

It connects with a safety cable that houses a power cord and communications cable. Attachments are added to clean, paint, carry tools and take pictures.
