DIY 18-ft.-High Robotic Exoskeleton
Hacx sends along a piece from PopSci that begins "Carlos Owens had handled all kinds of machines as an army mechanic, but he always dreamed of using those skills for one project: his own 'mecha,' a giant metal robot that could mirror the movements of its human pilot. Owens, 31, began building an 18-foot-tall, one-ton prototype at his home in Wasilla, Alaska, in 2004. Working without blueprints, he first built a full-scale model out of wood. Moving on to steel, he had to devise a hydraulics system that would provide precisely the right leverage and range of movement. He settled on a complex network of cables and hydraulic cylinders that can make the mecha raise its arms, bend its knees, and even do a sit-up. ... He foresees mechas having uses in the military and the construction industry, but acknowledges that right now they're best suited to entertainment. The first application he has in mind: mecha-vs.-mecha battles, demolition-derby style."
People are approaching the idea of mecha ass-first.
These proposed engineers of mayhem mostly treat "BIG FUCKING ROBOT OH YEAH" as an end in itself. In any semi-realistic context mecha should be seen as something that naturally evolves into being as agile, versatile exoskeletons are made progressively more powerful; you have to work up to big with a design where everything else works superbly, you can't work from big down. Otherwise any advantage gained by size will be hugely offset by the sad fact that the thing moves like a turtle in molasses.
Mecha become reasonable when they can move and maneuver with the same agility as a human being -- think Eva, which can run, dodge and so on with considerable finesse. (Here's waiting for those carbon nanotube aerogel artificial muscles, by the way.) But since we can't even do that for a human-sized exoskeleton, any effort to build a mecha that's not severely dysfunctional is going to be impotent.
