Robots learn to read

They will be equipped with X-ray specs or specialized radar technology.
Robots have already learned to map their surroundinngs and to pick up objects.
They say it should be relatively easy, using a software optical carachter recognition which automatically transforms scanned images into text.
But still there are some problems, like picking up words embedded in a busy scene.
Another problem is identyifing words that are difficult reading because of viewing perspective.
But the future will make softwares more and more sophisticated, in order to overcome these difficulties.
