13:18 rue_house .
19:39 rue_house here?
19:39 rue_house her!]\
19:39 ^kat^ me!
19:39 e_house jumps up and
19:39 rue_house here! here!
19:39 at^
19:41 ^kat^ is 0.5 mm nitinol weaker than 1 mm nitinol ?
19:41 ^kat^ do they react faster than the other?
19:51 ^kat^ da$%&^*it, i just realised i forgot about the dinner i cooked 2 hrs ago, and this morning, and last nite, and never got around to finishing and eating
20:36 ^kat^ http://www.bostondynamics.com/img/Atlas-p1red.jpg <<== why are it's knees in different places?
20:43 ^kat^ http://www.fastcompany.com/3050028/fast-feed/team-usa-seeks-500k-on-kickstarter-for-ultimate-robot-battle-with-japan?partner=rss&google_editors_picks=true
21:12 rue_house I would think so
21:12 rue_house oh retraction weaker?
21:12 rue_house perspective
21:12 ^kat^ o
21:13 rue_house seen a youtube video of that
21:13 rue_house its SLOW
21:13 rue_house (its hydraulic)
21:13 ^kat^ poor excuse
21:14 rue_house almost all hydraulic things are slow
21:14 ^kat^ yo ever see how fast water will exit a 10" pipe at 90psi? I didn't either
21:14 rue_house thats why my mecha is pneumatic
21:14 ^kat^ <WHAM>
21:14 rue_house indeed
21:14 ^kat^ <me> wtf?!?
21:14 ^kat^ oh, the pipe cap came off
21:15 ^kat^ luckily it missed me, and there wasn't that much water, just some valve eakage
21:16 rue_house I'v heard some stores about 150psi water mains
21:17 ^kat^ it took less than an eye blink for that cap to imbed in the opposite side of the trench and me to be totally entirely soaked to the skin
21:18 ^kat^ usa nuke missile subs use essentially a rocket engine to pressurize the water that ejects icbm from the sub
21:19 ^kat^ so being slow because it's hydraulic, is a poor excuse
21:21 ^kat^ that water slug pushes the multi-ton icbm outa the sub and clear of the water into the air, before the icbm's engines light off
23:11 rue_house .
23:11 katsmeow-afk ,
23:12 rue_house yea, nobody does it to be fast
23:12 rue_house and those cylinders cant move fluid fast enough for the parts their using
23:12 rue_house if you saw the video, you would also notice their underpowered engine
23:12 rue_house every time the bot moves is grunts
23:13 katsmeow-afk so they have no pressure storage?
23:13 katsmeow-afk dumb
23:13 rue_house nothat I can tell
23:13 katsmeow-afk and prolly too-small lines and connectors
23:13 rue_house and valves that are too small
23:14 katsmeow-afk hydraulics are notorius for doing things like having a 1/8 bore in a connector for 1/2 pipe
23:15 rue_house yup
