What it does: Designs and manufactures remote-control robots for industrial purposes--such as cleaning nuclear and hazardous waste sites, like power plants. Why it's growing: From Wisconsin to the United Kingdom, there's still quite a bit of nuclear waste left over from the Cold War, says CEO and co-owner Michael Cappello. But the company is increasingly branching out into other areas, including chemical waste cleanup. Long arm: S.A. Robotics is developing what may be the longest robotic arm in the world--a 104-foot device that will place pollution-filtering caps on the smokestacks of cargo ships docked in the L.A. harbor.
