Rock Climbing Robot Can Carry a Load, Sets Sights on Mountain Rescues

Robot could be used to scout or send stranded climbers supplies
While it weighs just a little over a kilogram (~2.2 lb), the newly minted wall-climbing robot exhibits Spiderman-like strength, hauling a load of 7 kilograms (15.4 lb) up steep surfaces.
Created by researchers at the
Eidgenössische Technische Hochschule Zürich
(ETH Zürich) -- known abroad as the Swiss Federal Institute of Technology -- the climber bucks the trend of past designs that used gecko-like high-surface-area attractions (via
tiny synthetic hair-like setae
) to stick to the wall. Instead, the robot uses a unique tacky adhesive.
The adhesive is heated by resistors to melt, with a melting temperature of 70 degrees Celsius (158 degrees Fahrenheit). Beyond that point it becomes a liquid, but remains tacky. The tacky adhesive penetrates cracks and crevices, fixing the robot to the surface. But when allowed to cool it recedes, freeing the robot foot to take another step.
The resulting climber has tremendous potential for use in mountain
or mining rescue
operations, either carrying imaging and audio equipment to hunt for lost hikers, or transporting supplies to hikers in difficult to reach areas. Larger models with improved adhesives could eventually be used to haul down hikers off the cliff face, but even in its current form the bot has a lot of promise.
The robot could also see use hauling light materials in high rise construction, having been tested on wood, plastic, stone and aluminum.
Liyu Wang, one of the robot's designers,
, "Our technology uses thermoplastic adhesives, which are much stronger than those used in gecko-type climbing systems. We are thinking about using this to climb cliffs or other complex natural environments, which no previous climbing technologies can handle."
on the bot was published last month in the peer-reviewed journal

If you missed the point of the this research then here it is
1. Proof of concept that it works
2. The technology is there and available
Problems making it work for its purpose
2. Still not mature enough
What is needed for it to work and have widespread adoption
1. More research and development
2. Parts to manufacture are economical
3. Someone to come along and absorb that R&D cost. That someone will not come along if it they don't see a profitable future.
3b. Government funding
