sonar simulator I have working...

formatting link

I have crawled around the net and found enough
information to get this to work.
simulated floor plan. simulated sonar "beam"
local map is created from scans. do multiple
scans and the data is fused to create a
decent picture of what is around.
simulator only lets you scan to north in
180 degrees. no code to allow turning the
fun and neat. the logic behind all of
this seems to lead to so many more solutions
to robotics problems.
I am working on converting all floatingpoint
and trig functions to assembly to speed the
I am using constants for probabilities of
obstruction/non obstruction. I give sensor
%100 accuracy weight.
next upload will move robot around and map
out all unexplored areas. I have this
working but it takes a few hours to explore
a small map... should get the same performance
or maybe 2X increase with real hardware...
to simulate sonar alot of math is involved..
interesting thing about simulators... you
start to write code and then you want to test
it. doesn't take much to give a visual representation
to see what is going on in the code.
I cannot leave this machine. there are piles
of parts all around me. I draw schematics on
the walls. I write notes on the walls. wires
and powersupplys and circuit boards litter the
floor. this is where I want to be.
