00:20 tsmeow-afk can just imagine it wandering around, giving the family pets something to do all day, spitting water on them, snorting, hopping and boun
00:22 katsmeow-afk and then when owners are home, it sits quietly like any table, except for spraying water at the pets if they get too close
00:22 rue_house heh
00:30 katsmeow #$*$^$ ala#$^&#%bama isp
00:33 slidercrank katsmeow, a greeting from Russia to Alabama :)
00:34 tsmeow wave
00:36 slidercrank I've been to Alabama :)
00:36 katsmeow i bet you were very happy to leave Alabama !
00:36 slidercrank we have a café named "Alabama". I don't know why but it's popular to give cafés the names of American states :)
00:37 slidercrank I've never been to the Alabama state though :)
00:37 katsmeow ah, ok
00:42 katsmeow i have never been to Georgia the country
14:56 _TK_ Hey!
14:58 deshipu ho
14:59 _TK_ Have had connection problems.
14:59 deshipu happens
14:59 _TK_ Been trying to answer|ask questions :P
15:00 deshipu ain't seen any
15:00 _TK_ How reasonably could one obtain|build a robot arm able to lift|manipulate ~ 512 g or so?
15:00 deshipu what speed and reach?
15:02 _TK_ Speed doesn't have to be very fast.
15:03 _TK_ ...and various reaches are imaginable to be useful.
15:03 deshipu how fast is "not very fast"?
15:04 deshipu here is one from a random search: http://www.strobotics.com/small-articulated-robot.htm
15:04 _TK_ ...could be like a peacefully operating human, relatively smooth.
15:04 deshipu 9350 USD, they have a promotion
15:08 _TK_ Hmm...
15:09 deshipu there is one with 100g payload for 133 USD: http://www.robotshop.com/en/lynxmotion-al5a-robot-arm-hardware-4dof.html
15:10 deshipu they also have a 280g version
15:11 _TK_ also found https://www.kickstarter.com/projects/ufactory/uarm-put-a-miniature-industrial-robot-arm-on-your/description
15:11 _TK_ ( which claims at least a can of coke )
15:12 deshipu _TK_: an empty can of coke :)
15:14 _TK_ Oh :| :P
15:15 deshipu if it's full, then it's 370g
15:15 deshipu _TK_: what are you trying to do?
15:21 _TK_ Hoping to help make more efficient and intellectual some tasks like transporting liquid from one container to another.
15:22 _TK_ ...eg to help prepare edible things for biological life-forms.
15:23 deshipu the mechanical part is the easy problem here
15:25 _TK_ ( ...Especially when someone's sick and can be helped by different teas and stuff coming frequently enough. )
15:30 _TK_ ( Can be hard to keep up alone in such scenarios sometimes. )
15:32 _TK_ You mean the programming would be the hardest?
15:32 deshipu yes
15:32 deshipu especially visual recognition and tracking
15:35 _TK_ ...Perhaps.
15:36 _TK_ To start out, one could have a work area with constrained positions.
15:40 deshipu someone has to prepare all the items and put them in reach of the robot
15:42 deshipu then someone has to input all the data required for the robot to recognize, locate and manipulate them -- that is, separate from writing the program for the robot
15:45 _TK_ ...that is true though the effort can be optimized and amortized.
15:48 deshipu preparing food with hands the way humans do is inefficient
15:49 deshipu most kitchen robots are much more specialized
15:49 deshipu and look more like production lines
15:56 _TK_ Thought that an arm could provide a general purpose 'quick-start'.
15:57 _TK_ ( and that it perhaps could help establish those specializations some time :) )
15:58 deshipu there is a very cheap small open-source robot arm called 'meArm' -- you could get it and try to program it to do anything and see how hard it is
16:02 _TK_ Checked it out, seems interesting :)
17:09 _TK_ deshipu, thank you for extra leads!
17:10 deshipu good luck
17:24 veverak deshipu: meArm looks nice
17:25 deshipu you can cut it out yourself, it's on thingiverse
17:25 deshipu I want to try it at some point
23:04 rue_shop3 armyofevilrobots, I'm tyring out the 1mm nozzel I made, this is quite educational
23:18 armyofevilrobots Awesome. I bet you’re getting awesome layer-layer adhesion.
23:19 armyofevilrobots You can print 1/1.618 layers right now and they’ll work awesome.
23:30 rue_shop3 no adhesion problems, I'd say I have a 'cave man print job' problem
23:30 rue_shop3 .7mm needs tuning, I'm dialing back to .5mm
23:57 rue_shop3 hmmmm
23:58 rue_shop3 armyofevilrobots, what material should we target for making filament?
