rlm@129 11 * Brainstorming different sensors and effectors.
rlm@129 12
rlm@129 13 Every sense that we have should have an effector that changes what
rlm@129 14 that sense (or others who have that sense) experiences.
rlm@129 15
rlm@129 16 ** Classic Senses
rlm@129 17 | Sense | Effector |
rlm@129 18 |------------------------------+---------------------------------|
rlm@129 19 | Vision | Variable Coloration |
rlm@129 20 | Hearing | Speech |
rlm@129 21 | Proprioception | Movement |
rlm@129 22 | Smell/Taste (Chemoreception) | Pheremones |
rlm@129 23 | Touch | Movement / Controllable Texture |
rlm@129 24 | Acceleration | Movement |
rlm@129 25 | Balance (sense gravity) | Movement |
rlm@129 26 | | |
rlm@129 27
rlm@129 28 - New Senses/Effectors
rlm@129 29 - Levitation
rlm@129 30 - Telekenesis
rlm@139 31 - control of gravity within a certain radius
rlm@139 32 - speed up/slow time
rlm@139 33 - object creation/destruction
rlm@129 34
rlm@129 35 - Symbol Sense
rlm@129 36 Where objects in the world can be queried for description /
rlm@129 37 symbols.
rlm@129 38
rlm@129 39 - Symbol Marking
rlm@129 40 The ability to mark objects in the world with your own descriptions
rlm@129 41 and symbols.
rlm@129 42
rlm@129 43 - Vision
rlm@129 44 Distinguish the polarization of light
rlm@129 45 Color
rlm@129 46 Movement
rlm@129 47
rlm@129 48 * project ideas
rlm@129 49 - HACKER for writing muscle-control programs : Presented with
rlm@129 50 low-level muscle control/ sense API, generate higher level programs
rlm@129 51 for accomplishing various stated goals. Example goals might be
rlm@129 52 "extend all your fingers" or "move your hand into the area with
rlm@129 53 blue light" or "decrease the angle of this joint". It would be
rlm@129 54 like Sussman's HACKER, except it would operate with much more data
rlm@129 55 in a more realistic world. Start off with "calestanthics" to
rlm@129 56 develop subrouitines over the motor control API. This would be the
rlm@129 57 "spinal chord" of a more intelligent creature. The low level
rlm@129 58 programming code might be a turning machine that could develop
rlm@129 59 programs to iterate over a "tape" where each entry in the tape
rlm@129 60 could control recruitment of the fibers in a muscle.
rlm@129 61 - Make a virtual computer in the virtual world which with which the
rlm@129 62 creature interacts using its fingers to press keys on a virtual
rlm@129 63 keyboard. The creature can access the internet, watch videos, take
rlm@129 64 over the world, anything it wants.
rlm@129 65 - Make virtual insturments like pianos, drumbs, etc that it learns to
rlm@129 66 play.
rlm@129 67 - make a joint that figures out what type of joint it is (range of
rlm@129 68 motion)

rlm@73 109 * Intro
rlm@73 110 So far, I've made the following senses --
rlm@73 111 - Vision
rlm@73 112 - Hearing
rlm@73 113 - Touch
rlm@73 114 - Proprioception
rlm@73 115
rlm@73 116 And one effector:
rlm@73 117 - Movement
rlm@73 118
rlm@73 119 However, the code so far has only enabled these senses, but has not
rlm@73 120 actually implemented them. For example, there is still a lot of work
rlm@73 121 to be done for vision. I need to be able to create an /eyeball/ in
rlm@73 122 simulation that can be moved around and see the world from different
rlm@73 123 angles. I also need to determine weather to use log-polar or cartesian
rlm@73 124 for the visual input, and I need to determine how/wether to
rlm@73 125 disceritise the visual input.
rlm@73 126
rlm@73 127 I also want to be able to visualize both the sensors and the
rlm@104 128 effectors in pretty pictures. This semi-retarted creature will be my
rlm@73 129 first attempt at bringing everything together.
rlm@73 130
rlm@73 131 * The creature's body
rlm@73 132
rlm@73 133 Still going to do an eve-like body in blender, but due to problems
rlm@104 134 importing the joints, etc into jMonkeyEngine3, I'm going to do all
rlm@73 135 the connecting here in clojure code, using the names of the individual
rlm@73 136 components and trial and error. Later, I'll maybe make some sort of
rlm@73 137 creature-building modifications to blender that support whatever
rlm@73 138 discreitized senses I'm going to make.
