options  lumi's picture  Awesome....more, more, more please ;-)
Could you try to explain how the mapping is working? Does it
require a EPROM to save data or do you just store it in te
memory?  What servos are you using? With my Chopstick Junior I
got some broken after a while...yeah, that cheap 9g servos...
Botdev's picture  You don't need the write it in the eprom, it
keeps a very small amount of data in realtime (does not keep a
log), so the memory is enough. Although, you can use the same
concept in a way where you log the data for more complex
calculations. It has a very low resolution of 10x2. Basically
what it does it to create an array of distance values (from the
IR sensor) as the head moves. If you watch it as it moves
forward, you will see a circular-like movement of the head, it
scans 2 lines (one 90 degrees to the ground and one 45 degrees
to the ground). I keep 10x samples for each line and store them
in an array. After that it depend
