Everything about the interface is simplified. I watched as the iRobot exec demonstrated all the key capabilities and then he handed me the tablet. I was able to drag my finger on the screen to where I wanted the Packbot robot to go, see a yellow predictive path on screen and then watch the robot drive along it. I tapped an onscreen button to change speeds (it could go quite fast), and when I wanted to pick up a bottle, was able to virtually grab the arm and move it into position, while the robot mimicked my actions in the real world. It was all so obvious and easy.
