I laughed when the interviewer asked what happens if someone tries to steal a robot. The guy answering started off by saying it would be really hard as they weigh 92 pounds. Oh that's sooooo heavy.
Completely agree. Also, this is an "honest" system which may work only in developed countries. This type of technology would never be used in any third world countries because both merchendises and robots would be stolen in a heart beat.
But my first impression was that the robots were too short for the sales experience. The customers in the store would have had to stoop or bend over to be "face to face" with the telepresence operators. I'm guessing that the height was a compromise between a robot "sitting at a desk" and "walking around".
That may be the case. However, I don't see that it is a problem. Also, they could easily improve it and make the screen tilt up and down. By pushing from the bottom part of the screen to tilt upward, they could face a tall person, and leave it the way it is to face a shorter person.
