BioMetal Fiber Walking Robot Inchworm

BioMetal Fiber Walking Robot Inchworm All killer robots have to start somewhere. What will eventually one day be a muscle made of BioMetal Fiber capable of lifting humans into the air and crushing their skulls with one arm must have a beginning. And that beginning is the BioMetal Fiber Walking Robot Inchworm.We love this little walker; read on to find out why! Each BioMetal Fiber Walking Robot Inchworm has one strand of BioMetal Fiber. When current is applied, the fiber heats up and contracts. This pulls the Inchworm's feet apart. When the current is stopped, the fiber cools and expands. Add a little grippy fabric on the bottom of each foot and the spring to return it to its original position, and you can easily see how the little inchworm can walk along most non-slick surfaces. The BioMetal Fiber Walking Robot Inchworm is a great desktop toy, but it could also be the focus point of a killer science fair project. Remember, though, to treat your BioMetal Fiber Walking Robot Inchworm with respect - 'cause when it's great grandson of a killing machine comes around, you'll need all the good references you can get!
