As Palmisano points out:
Back in the day, the founders of iRobot had been against the weaponization of robots. Perhaps business and financial pressures are pushing the boundaries. Indeed, the military market is becoming ever more important, according to the company's first quarter results. Finances were very tight in 2009 and many engineers, which in my professional opinion are very talented individuals, are getting paid below wage standards in the industry. iRobot probably sees military systems as a market they'll have to explore and expand.
