Just like people, robots do things better with two hands. More dexterous robots will be valuable in several applications, from surgery to materials handling, or even picking up samples as they walk across the surface of Mars. A step -- perhaps a grasp -- in the right direction is the small robot with two arms, two hands, and opposable thumbs described in Dual-Armed Robot Making In-Roads.
At Automate 2011, the SDA5D lifted spherical objects from a nearby table. It's being adopted in industrial applications from logistics and palletizing to automated assembly and distribution. A larger model is deployed in automotive assembly plants and by the National Aeronautics and Space Administrtion (NASA) for space simulation operations.
