I spoke with some Willow Garage employees.
Here is some information I got from speaking with the Willow Garage employees.
* There are now 50 employees of Willow Garage
* There are 60 PR2 robots deployed around on the world
* A full price PR2 is $400,000
* There are two spinoff robot companies from Willow Garage (Turtlebot and Suitable Technologies
* Suitable will have the tablet for a head robot, which may companies are working on. In 22 days Suitable will announce something and launch their website. they are focused on using the tablet bot for telepresence.
* Kinect and Leap Motion devices for motion capture are making the sensors far cheaper than the planar laser scanning devices.
* higher resolution cameras are currently not helpful for robots. The algorithms that are currently used would analyze a pixel at a time and higher resolution would increase the computational costs. The PR2 has a 5 megapixel camera now and it is never used because the low resolution VGA camera is good enough
* If there were smart radio tags used to label an environment that would make it easier for a robot to operate. Thin Film Norway has smart radio tags which will be available for pennies. This would be useful for environments like a business or industrial setting where the environment can be controlled to allow for complete labeling. There would be the need to control any dynamic elements (ie unpredicatable people)
