You're simultaneously overestimating and underestimating the state of computer vision. It's really kind of cute. It's actually very easy to make a 3D model of the world from sensor data now using a variety of simple, fast methods. The difficult part is perceiving what this data IS!
As a researcher in AI and robotics, I can assure you that we're a very, very long way off from having artificial intelligence which is even close to functioning autonomously in a human environment. I'd put the level of understanding and sophistication of current AI algorithms at about the level of a fly, or perhaps a cockroach if we wish to flatter ourselves. I think the closest we are to commonplace autonomous robotics is having autonomous cars, but even that has significant hurdles to overcome before it becomes commonplace (the typical $1,500,000 price of the sensors, for instance).

So yes, I have
The rest of the "civilized" world (Europe for example) is being slowly overtaken by Islamofacist poised to send your nation to the far right~ at warp speeds. Better get brushed up on sharia law as I don't see the rest of the "civilized" world doing anything to stop it.
Ironic, because that's exactly the kind of bullshit rhetoric the far-right in Europe uses!
I'm surprised they picked the PR2 from Willow Garage and compared with the Anybot. Willow Garage also makes the Texai robot, which has almost identical capabilities as the Anybot, and fulfills the same kind of role. PR2 and HRP are not designed for offices, but are research robots which are loaned out to universities and other institutions. Neither is designed to be a commercial robot, while Texai and Anybot are commercial products.

Because ALLEGED child molesters and rapists
This is why black lists and branding shouldn't be used as punishments. I can imagine there are several innocent people convicted of some kind of sexual crime now on a hiring black-list, putting signs in front of their houses, being tracked by GPS, etc.
If we're going to brand citizens convicted of sexual crimes, why not also brand all other criminals. After all, you wouldn't want to do business with someone convicted of thievery, right?
So to find a truly earthlike planet, won't they have to focus on a single star for more than a year in order to detect the planet passing the star more than once?
Yep. And for Jupiter-like planet we'd need to be watching it for hundreds, if not thousands of years if we were to use this method.
What if the planet's orbit never aligns to eclipse the sun?
Then we would never detect it via this method.
What if there are two or three planets in very similar orbits?
It depends on how well they are aligned. Even if they're perfectly aligned, we're liable to see the first one before the second or third one as it passes in front of the star. If they are even slightly out of phase, they will eventually be in an orbit in which we see all three distinctly. In any case, the radius and shape of the occlusion in front of the star is determined by the shape of the light intensity vs. time graph. Circular disks have a very specific light occlusion shape, while abberant occlusions have different shapes.
Two ways:
1. The graph of light intensity vs. time has a particular shape for perfectly spherical objects such as planets passing in front of a star.
2. Those doppler shifts would not be affected by a sun-spot, and measurements of this kind aren't always verified by doppler shift methods.
The hardest part of climbing the ladder of success is getting through the crowd at the bottom.
