Remember El-E, the service robot that would retrieve things that you spotted with a laser? The creators of El-E are doing research into other methods of making assistance robots. Their latest contraption is an iRobot Create, basically a Roomba, with a custom grasping hand. Instead of complex multi DOF assemblies, they have made something that works on the same principle as a dustpan. It has a thin wedge and a sweeping arm that loads items onto it. As you can see in the video, it is quite effective.
