How can I say that? We'll just like I did above. I am definitely a robotics person as you assumed but I don't need a machine just to crush my own soda can. Think about it, you would have to place the can in the machine, flip a switch to turn on the compressor, wait for the air tanks to fill, flip the switch to turn off the compressor, turn a pressure regulator to crush the can, and then release all pressure from the system to get the can out. I would prefer the three simple actions of the "primitve" method: put the can down, step on it, pick the can up. The pneumatic bridge breaker however is very worthwhile because it breaks the wood bridge in a matter of seconds with very little setup. The primitve way of bridge breaking required ten minutes of setup to position, hang, and level a platform and another several minutes to place books on this hanging platform.
