Toy Robot climbs walls, defies gravity
The Climb@Tron R.E.X., which stands for “Robot Explorer” can climb walls using vacuum suction to stay up , it runs on AAA Batteries.

‘These climbers defy gravity and provide hours of imaginative play! Using a powerful vacuum suction system, the Climb@Tron R.E.X. easily scales smooth surfaces like glass, mirrors, and metal file cabinets with its retractable suction-cup feet! Fun to watch – get two are see which one climbs faster.’
They are available online from Scientifics for $10 (about £5).

Whoa.. this is good..
maybe I’ll back link to your blog..
It is good info…
I assume these are quite small for £5? =D and for taking batteries also
Wow, this toy has been around for at least 15 years!
(I know, i got one back then)
There is nothing amazing about it, it is a cheap, one motor camshaft. The suction cups only work on really smooth surfaces.
