Progress is a bit slow at the moment. Trying to plan out the next section. In the meantime, I'm adding a chapter on navigation using lasers, and also refining what I've written so far. From tomorrow and on I will have no other course to worry about, which is a good thing as I'm preparing to take on the final chapters of this thesis.
Also, when fed up with writing I've been looking at programming libraries (vision, audio, speech...) and some random things that pop into my head from time to time. I just wish computer vision algorithms were better, as vision has huge potential in a travelling aid for someone who lacks it. I want a system to read informational signs in the environment and to tell me if that bus over there is the right one. I'm also giving self-containment a priority, that is, the device should try to rely as little as possible on external information (which might not exist in some places). That doesn't mean such information is useless, however.
I've also tested an ER1 robot. I am able to move it and have it recognise (and say aloud) objects and follow them. It really likes looking at CD's.
