17:10 zhanx skipping the boring parts, : http://youtu.be/-eej-7t5q7c tell me if you think it will work
19:36 rue_house you would have to severly limit the accel/deaccel
19:57 zhanx or, help balance a 5' biped robot and use less power
19:58 rue_house I had a design for a camera boom that worked a bit like that
19:59 rue_house a counterweight did the majority of te acceleration
19:59 rue_house Lolina8088, I found them, in a strange corer o hte livingroom :)
19:59 zhanx need shocks also for the legs
19:59 rue_house ** 4 days till maker faire **

20:09 rue_house the side table by the couch
20:10 Tom_itx the sandwiches?
20:11 rue_house no the $200 new work boots
20:12 Tom_itx oh
20:12 rue_house Cable length: 300 meters (tolerance 20 meters)
20:12 rue_house hahaha
20:12 rue_house 300m+-20
20:16 Lolina8088 any word from your ma?
20:19 rue_house ah! I'll call
20:24 Lolina8088 http://gibsonsflowerbarge.blogspot.ca/
20:24 Lolina8088 I need content.
20:24 zhanx triangle math is FUN!
20:24 rue_house I'v left message
20:25 rue_house awesome
20:25 rue_house I'll work on content
20:25 zhanx doing the math for distance (basics right now) calculations for my robot
20:25 rue_house zhanx, tractor drive?
20:26 zhanx gear driven, after next weekend you will understand more
20:26 rue_house Lolina8088, so tempted to facebook it
20:26 zhanx i wanna facebook it
20:30 zhanx rue gonna make a quick thing tell me if i am right ok?
20:48 zhanx https://lh5.googleusercontent.com/-tldA0ZTQEF4/UaQJd59_crI/AAAAAAAAD9k/sKfQLMS3TRE/w457-h539-no/triangle1.png
20:48 rue_house wtf are yo uup to
20:49 zhanx :D
20:49 zhanx umm well its not the bests
20:49 zhanx but if i know C
20:49 rue_house this is making my head hurt, is there a mental virus embedded in this image?
20:50 zhanx i can calc a few things and get the distance and height of the object
20:50 rue_house can i have a reference index?
20:51 zhanx umm not at this time, you can make one up
20:51 rue_house I dont know whats placeholder and what literal
20:51 zhanx all 1 are placeholders. Capitols are literal and know
20:52 zhanx known
20:52 zhanx http://myinventions.pl/024/3Dscanner.png
20:52 zhanx something like that is best i can google
20:52 rue_house C - distance between cameras - known
20:52 zhanx A know wide of field of view
20:52 rue_house is B the lens angle?
20:52 zhanx yes
20:53 rue_house ah
20:53 rue_house how do you know the field of view width if you dont know the target distance
20:53 zhanx all lower case calc'd off the known
20:54 zhanx its x pixels wide, and that was a curve ball thanks
20:54 zhanx b is now lower case
20:54 zhanx correction a
20:54 rue_house is this arbitrary vision mapping or controlled environment
20:55 zhanx arbitrary of course :D
20:55 zhanx do i do anything easy?
20:55 rue_house ok, want advise from an extra terrestrial?
20:55 zhanx sure
20:56 rue_house dont try to do everything with stereo vision
20:56 zhanx ok, how about compare them ?
20:56 rue_house instead, find unique points and watch how far they move when the camera shifts a know amount
20:56 zhanx k
20:56 rue_house move the move, the closer they are
20:56 zhanx yep
20:57 rue_house if your on a system already in motion, use an accel to track the motion
20:57 zhanx and will be using a training set of know items also
20:57 zhanx k
20:57 rue_house the only time it siezes up is when you stop
20:57 rue_house you ust need to find monuments to track
20:57 rue_house think of it as image stabilization in reverse
20:57 rue_house kinda
20:58 rue_house and one last thing
20:58 zhanx ok so i am 90% on track
20:59 rue_house dont tell people extra terrestrials exist or they will think your crazy.
20:59 rue_house crap, I have to run
20:59 zhanx ok laters
21:13 zhanx rue_house, darn i show you my robot stabilization outline?
23:00 rue_house mmm I cant take any new projects on right now
