[01:41:30] <rue_house> my dxf library is comming alonggreat
[01:45:29] <katsmeow> congrats
[01:45:40] <katsmeow> you are up awefully late
[01:45:42] <katsmeow> i am too
[01:46:35] <rue_house> good save
[01:46:41] <rue_house> I give up on sleep
[01:46:49] <rue_house> it dos't matter if I go to bed on time
[01:47:06] <katsmeow> i ate a sleepy pill, i am passing ut
[01:47:08] <rue_house> besides, I *just* managed to finish making supper
[01:47:32] <katsmeow> ever considering making supper when you get home from work ?

[01:47:52] <rue_house> no, I'm too tired, I go to bed and sleep for like an hour
[01:47:58] <rue_house> ;)
[01:48:02] <katsmeow> o
[01:48:35] <katsmeow> i have a half-a-double-cardan as elbows and knees in mind
[01:49:03] <katsmeow> to permit a full 180-0-180 swing of the lower arms and legs
[01:49:04] <rue_house> err, cannot correct cardon
[01:49:17] <rue_house> ok
[01:49:55] <rue_house> still cant correct 'cardan'
[01:50:12] <katsmeow> https://duckduckgo.com/?q=double+cardan+joint&iax=1&ia=images
[01:50:35] <rue_house> oh
[01:50:41] <rue_house> a universal
[01:51:10] <katsmeow> if the two shafts coming to the joint are geared together so if one is at 20 degree to the center, the other one is at -20 , making a total of 40 degree turn,
[01:51:17] <rue_house> yup
[01:51:23] <katsmeow> then the upper and lower linb can fold up against the upper
[01:51:46] <rue_house> ah yes
[01:52:04] <katsmeow> there's must less space conflict after the joint gets to 90, just because there's two joints at 45
[01:52:22] <rue_house> there is a cheat way too
[01:52:28] <katsmeow> well, the bug in the oitment has been the gears, they take up too much space
[01:52:32] * rue_house posts..
[01:52:34] <katsmeow> and they develop slop
[01:53:22] <katsmeow> so, use cables to keep the in-between spacer at 1/2 the total angle
[01:54:11] <katsmeow> this also automagically puts the tendons to the lower limbs much farther out (leverage-wise) when at 90 degrees
[01:54:31] <katsmeow> btw, you never posted that video for tonite?
[01:55:49] <rue_house> http://ruemohr.org/~ircjunk/robots/sparrow1/p1070878.jpg
[01:56:01] <rue_house> middle images, sorry, min focus length
[01:56:13] <rue_house> with the offsets
[01:56:14] <katsmeow> the the car-truck double cardans, there's a center pin that engages the center piece to keep it at 1/2 the overall angle, but that won't work when the overall angle is 180
[01:57:31] <rue_house> ?
[01:57:47] <katsmeow> that offset allows a full 90 swng, but not a 180 swing
[01:58:02] <katsmeow> oops
[01:58:05] <rue_house> :)
[01:58:11] <katsmeow> a 0-180, but not a 180-0-180
[01:59:01] <rue_house> I'm not finding many joints that need more than about 100
[01:59:34] <katsmeow> i wanted to make "front of the robot" be a relative term, not an absolute
[01:59:50] <rue_house> I'm just shooting for almost human
[01:59:55] <rue_house> I have 94? axies
[02:00:26] <rue_house> 46 axies
[02:00:43] * rue_house is sure the page is the right way up this time
[02:02:17] <rue_house> if you want my list, I can round it up
[02:02:25] <rue_house> hand reduced to 3 digits
[02:03:19] <katsmeow> i aer far more interested in what yo will use for muscles

[02:03:22] <rue_house> 1:1
[02:03:48] <rue_house> the baloons are having issues, apparently most baloons are made of biodegradable rubber
[02:04:08] <rue_house> I might have to use special baloons made for other purposes
[02:04:21] <rue_house> http://ruemohr.org/~ircjunk/robots/sparrow1/p1040015.jpg
[02:04:22] <rue_house> 1:1
[02:04:33] <katsmeow> that's a big paw there
[02:04:35] <rue_house> http://ruemohr.org/~ircjunk/robots/sparrow1/p1040018.jpg
[02:04:56] <rue_house> 8' ladder, my head clears its crotch
[02:05:39] <rue_house> http://ruemohr.org/~ircjunk/robots/sparrow1/p1070328.jpg
[02:05:46] <rue_house> you know I have a finger made, right?
[02:05:52] <katsmeow> no
[02:06:18] <rue_house> I'm working on how the tendons go, as soon as thats worked out, I'm a go on the rest
[02:06:39] <katsmeow> looks ike aluminum
[02:06:44] <rue_house> steel
[02:06:59] <rue_house> http://ruemohr.org/~ircjunk/robots/sparrow1/p1070365.jpg
[02:07:01] <rue_house> sand blasted
[02:07:13] <rue_house> its nothing you couldn't pull off in an evening
[02:07:52] <katsmeow> i'd be pouring alum inserts for the ends, and using ball bearings
[02:08:13] <rue_house> I want to go bushing
[02:08:17] <katsmeow> the inserts would add a great deal to teh strngth, and let you tightend down on the segment ends a lot
[02:08:21] <rue_house> excavators use bushings
[02:08:28] <katsmeow> i know
[02:08:39] <rue_house> thats my reasoning :)
[02:08:53] <katsmeow> heavy trucks use them in the front ends too, idiot decision
[02:08:55] <rue_house> grease the hell out of it
[02:09:24] <katsmeow> bush hog i had to replace the sleevs on every morning had sleeves too
[02:09:27] <rue_house> you saw the pipe core of those digits, right?
[02:09:34] <katsmeow> no
[02:10:03] <rue_house> http://ruemohr.org/~ircjunk/robots/sparrow1/p1070329.jpg
[02:10:10] <rue_house> the inner bit of each one is a peice of pipe
[02:10:18] <rue_house> well, its drilled bar
[02:10:21] <rue_house> its thick
[02:10:33] <rue_house> I just tacked it cause I dont know if any of this will work
[02:11:21] <katsmeow> so one end has a heavy drilled core, and the piece it fits to uses only the thinness of the segment itself?
[02:11:31] <rue_house> the whole thing is more or less 2.5x me, the hands dont come out super strong
[02:11:53] <rue_house> yes
[02:12:00] <rue_house> fair enough point
[02:12:41] <rue_house> but its only got a curl strength of like 150lbs
[02:13:13] <katsmeow> if the thinness one one side is strong enough, then it's strong enough that way on the other side too
[02:13:28] <katsmeow> you will need that space to run tendons thru
[02:13:55] <rue_house> I marked 5kg/cm on it, I think that means that the mecha is maybe 12.5kg-cm on some point of that finger
[02:14:08] <rue_house> I'm expecting to run them on the outside
[02:14:16] <katsmeow> oh
[02:14:18] <rue_house> its gonna have to wear gloves of some sort
[02:14:33] <rue_house> oh
[02:14:38] <katsmeow> so things don't get caught on the exposed floppy tendns
[02:14:48] <rue_house> the pin is upposed to be rotationally fixed to the thin section
[02:15:15] <rue_house> so its not roating on the thin metal
[02:15:40] <katsmeow> good
[02:15:56] <rue_house> I think that was part of the reasoning for not helping it
[02:17:51] <rue_house> I have just recently worked out how finger tendons work, I ahve to test and try implementing it
[02:18:05] <rue_house> but as you aired to, I could just put on a good ole clamp gripper for now
[02:18:09] <rue_house> change it out later
[02:18:14] <rue_house> get on with the build
[02:18:26] <rue_house> which means I need to work out the pressure sensors
[02:27:04] * katsmeow wavers gnites
[02:27:11] <katsmeow> gnite.wav
[21:24:57] <katsmeow> wierd weather today: winds blew fiercely one way , then reversed and blew fiercely the other way
[22:36:31] <katsmeow> "The universe is under no obligation to us not to be absurd."
[22:53:08] <Tom_itx> bad fires here
[22:53:35] <Tom_itx> and yes the wind did the same thing here
[22:54:25] <katsmeow> air was smokey here today, got worse hour by hour
[22:54:42] * katsmeow has a math situation to be verified
[22:54:58] <katsmeow> "One horsepower = 33,000 ft. pounds per minute"
[22:55:03] <katsmeow> 1 hp-minute = 33,000 lbs 1 ft 1 minute
[22:55:10] <katsmeow> 10 hp-minutes = 33,000 lbs 10 ft 10 minutes
[22:55:16] <katsmeow> 1000 hp-minutes = 33,000 lbs 1000 ft 1000 minutes
[22:55:22] <katsmeow> correct?

[23:33:02] <rue_house> hikat
[23:34:01] <rue_house> prolyl gonna come bak nice and greeen after that one
[23:35:43] <rue_house> I cant do those units because my units program insists that a pound is not an amount of force
[23:36:14] <rue_house> frustrating day, but I think its me
[23:58:20] * katsmeow hands rue some vitamins
