rlm@352 1 * Summary of Senses
rlm@346 2
rlm@352 3 vision -- list of functions which must each be called with
rlm@352 4 the world as their argument, each of which returns [topology data]. Each
rlm@350 5 element of data is a number between 0 and 255 representing the
rlm@352 6 intensity of the light recieved at that sensor. Each element of
rlm@352 7 topology is a pair of numbers [x, y] such that numbers whose pairs
rlm@352 8 have a short euclidean distance are generally physically close on the
rlm@352 9 actual sensor.
rlm@348 10
rlm@348 11 proprioception -- list of nullary functions, one for each joint, which
rlm@348 12 return [heding pitch roll].
rlm@348 13
rlm@350 14 movement -- list of functions, one for each muscle, which must be
rlm@350 15 called with an integer between 0 and the total number of muscle fibers
rlm@350 16 in the muscle. Each function returns a float which is (current-force/
rlm@350 17 total-possible-force).
rlm@350 18
rlm@348 19 touch -- list of functions which must each be called with a Node
rlm@348 20 (normally the root node of the simulation) the argument, each of which
rlm@352 21 returns [topology data]. Each element of data is [length limit] where
rlm@352 22 limit is the length of that particular "hair" and length is the amount
rlm@352 23 of the hair that has been activated so far. (= limit length) means that
rlm@352 24 nothing is touching the hair.
rlm@352 25

rlm@352 27 * A Flower
rlm@352 28
rlm@352 29 A flower is a basic creature that tries to maximize the amount of
rlm@352 30 light that it sees. It can have one or more eyes, with one eye being
rlm@352 31 "special" in that it is this eye which must recieve maximum light. It
rlm@352 32 can have multiple articulated joints and mulcles.
rlm@352 33
rlm@352 34 Want an algorithm that uses the sense data of =vision=
rlm@352 35 =proprioception=, and =movement= to maximum benefit in order to look
rlm@352 36 at the light source.
rlm@352 37
rlm@352 38 The light source will move from place to place and the flower will
rlm@352 39 have to follow it.
rlm@352 40
rlm@352 41 The algorithm should be generalize to any number of eyes and muscles,
rlm@352 42 and should become /more/ preformant the more sensory data is
rlm@352 43 available.
rlm@352 44
rlm@352 45 I will punt on working out an elegant model of motivation for the
rlm@352 46 flower which makes it want to go to the light.
rlm@352 47
rlm@352 48 Maybe I need a motivationless entity first, which just learns how its
rlm@352 49 own body works? But then, wouldn't that just be a motivation itself?
