Is there anything stupid than a useless robot? Yes. Two stupid robots fighting endlessly with each other.
In a video of him Caleb force, two robot they have stood against each other and are trying to erase each other. There are no real winners in this battle, o race it is like aimless and incessant.
The two similar machines are made for entertainment and are nothing more than a mechanical finger that closes the switch on-off every time you turn it on. That is, it actually disables itself.
In his video, Kraft has placed two of these machines across from each other and, using a tube to connect the two on-off switches so that they do the opposite movement, putting in an epic never-ending battle.
However, the trump card of this game is that you stick to something silly and you sit and look at it with hours.
