We launch the camera from the phone, or what to do when nothing works?



About eight years ago I worked in one ... but in other matters, no matter where. We did all sorts of different interesting things there. Including were engaged in technical vision systems for robots. The robots were a little small. And if making a small drive for them was not a special problem for us, then making a miniature digital camera that would not be half the size of a robot was difficult (when will we finally bury PAL in such developments and there will be a digital everywhere?). If you are curious to know how it all ended, please, under the cut!



A small disclaimer. Enough years have passed since the events described, the results of the work are not of any commercial interest (isn't that right, Comrade Major?), - , , .
