waderoush writes "One of the problems that kept PR2, a two-armed humanoid robot developed by Menlo Park, CA-based Willow Garage, from succeeding commercially was its $400,000 price tag. But as it turned out, only a handful of the 40 or so universities that own PR2s ever developed applications that use both arms. That's one of the reasons why UBR-1, a mobile manipulator robot from Willow Garage spinoff Unbounded Robotics, has only one arm. And that, along with many other engineering decisions and technology improvements, will allow the startup to sell its robot for just $35,000 (it's designed for materials-handling tasks in places like warehouses, elder care facilities, and supermarkets). 'With robots, feature creep is so much more present than in some other fields,' says Unbounded co-founder and CEO Melonee Wise. 'There is always this desire to make a Swiss Army knife. But you have to make compromises, and those compromises directly impact the capabilities as well as the cost of the robot.' One roboticist told Unbounded: 'Your robot is so inexpensive that if I needed to have a second arm, I'd just buy a second robot.'"
