fcc opened up 6ghz band for nextgen wifi devices

keep in mind El-E, the service robot that would retrieve things that you identified with a laser? The creators of El-E are doing research study into other techniques of making help robots. Their most current contraption is an iRobot Create, generally a  Roomba, with a custom-made grasping hand. instead of complex multi DOF assemblies, they have made something that works on the exact same principle as a dustpan. It has a thin wedge as well as a sweeping arm that tons products onto it. As you can see in the video, it is rather effective.
