| Light
seeker began as a single robot project. As the name
suggests, it directs itself towards the brightest light
spot around. Its a stationary robot and seems to work
well in the evenings with no sunlight around. Its behavior
is very interesting to watch. When there is no light
source, it rotates in search of it and when it finds
a very dim source it begins to swing in its direction
as if its not satisfied with it! And when it finds a
bright source, it locks on to it inspite of being placed
in every possible direction away from the source.
But
latter I realised that there were so many BEAM circuits
that circled around the same idea, that I decided to
make a single light seeking platform on which I could
test the various 'head' circuits. In this way, the common
elements like the motor and the battery remained the
same while the brain controlling them, varied. For me
this was the most economical way to get the things worked
out.
