12:52 rrawat Hey all
12:53 rrawat is anyone here?
12:56 veverak nope
12:57 rrawat do you guys know ROS?
13:14 deshipu not personally
13:16 mrdata rrawat, RTOS?
13:20 veverak rrawat: installing just now
13:20 veverak or trying to
13:27 rrawat haha
13:27 rrawat yeah ROS is the robotics operating system
13:27 rrawat it would be cool to know everyone's background
13:27 rrawat I want to have connections in the robotics industry
16:56 ace4016 i've seen a lot of ROS talk in here lately, but who actually uses it in the field?
16:58 ace4016 Baxter apparently
17:02 Snert_ what is ROS ?
17:02 maiden Robotic Operating System
17:02 maiden its awesome
17:02 maiden http://www.ros.org/
17:02 Snert_ I must check this out
17:02 maiden We used it in our robots for RoboCup
17:03 maiden I am going to use it in the 1:1 humanoid robot i am planning on now.
17:08 Snert_ ROS is not C++ based?
17:19 maiden Snert_ it is
17:20 maiden but there is a Python API as well
17:20 Snert_ Yes...seeing that.
17:20 Snert_ but then I got lost over in the Barrett gripper website
17:26 ace4016 lol
17:27 Snert_ so much goodshit out there
17:31 Snert_ can't find a $ on that Barrett gripper. Must be a megabuck
17:45 Snert_ anything I'd want is tooo expensive :(
17:45 ace4016 yup
17:45 ace4016 much cheaper if you build it yourself
17:45 ace4016 but that cost time
17:47 Snert_ time I gots. A decently equipped shop I don't.
17:47 anonnumberanon ace4016, for people who have no money time is not a problem, since they don't know how to use it in the first place
17:47 anonnumberanon should be quick fix
17:47 Snert_ I'll be doing wood, plastic and drill holes.
17:49 ace4016 hehe
17:50 Snert_ maybe buy a cheepo scrollsaw
17:50 Snert_ if it can't be done with that I aint doin it.
17:52 anonnumberanon does ros run on 8bit 32kb microcontroller?
19:04 ace4016 i somehow doubt tht
19:04 ace4016 such devices hate OS fluff
19:34 rue_house why do you mneed an OS on an 8 bit microcontroller
19:35 rue_house its supposed to be a SINGLE APPLICATION device
19:35 rue_house not managing tasks and crap, just doing one thing
19:35 rue_house real time
19:35 rue_house one thing
19:36 rue_house http://ruemohr.org/~ircjunk/projects/newpower/p1070573.jpg
19:36 rue_house I have a pcb waiting for me
19:58 Snert_ I prefer a real OS on my arduino-like devices too.
20:22 robotust1a gn
20:23 robotust1a night
20:35 ace4016 an OS seems like overkill for anything 8-bit, but that's just me :P
20:36 ace4016 i can see for 32 bit though
20:37 robotust1a ace4016: OS is ok for 8 bit controllers
20:38 Snert having standard tools like ping, traceroute and dig is what I like.
20:38 ace4016 what do you need the OS to do on an 8-bit MCU?
20:39 ace4016 those sound like libraries that are nice to have handy rather than entire kernels and the like
20:41 Snert I like to be able to ping about and ascertain my network surroundings using the standard commands.
20:41 Snert yet still do arduino stuff.
20:42 Snert so I guess I prefer more like an edison or galileo gen2 or at least a 2560mega.
20:43 Snert and lord knows, can't beat a beaglebone black.
20:44 robotust1a http://i.imgur.com/KCz25bd.png
20:44 Snert 1Ghz processor...4Gigs of bootable on board flash. Runs a full linux distro.
20:45 Snert only thing it's missing is onboard wireless and poe.
20:45 Snert and I give up on the poe.
20:47 robotust1a what about your robots?
20:48 Snert any robot I'd build would be run by an edison. Not at first. But I'd move it over from the arduino to the edison.
20:49 Snert bit by bit as I get it all working together.
20:49 Snert maybe leave a couple dedicated tasks to onboard dweenos.
20:50 robotust1a my robot will use 8 arduinos, 1 edisson, and 3 TX-1 boards
20:51 Snert sounds like a good split.
20:51 robotust1a it's approximare electronics
20:51 Snert I do not care for ethernet and wireless as an afterthought.
20:51 Snert it needs to be there right from the gitgo.
20:51 robotust1a may be 2 tx-1 boards
20:52 Snert what is this tx-1 board? got a link?
20:53 robotust1a nvidia tegra
20:53 ace4016 i suppose i'd use more powerful things for all the fancy stuff if i needed those features :P
20:54 robotust1a or I'll wait for new bpards
20:54 robotust1a boards
20:54 Snert yea, I'm thinking the new crop of boards will have the good things there already
20:55 Snert onboard wireless and enet on the yun is a step forward.
20:56 ert smells di

20:56 Snert off to munch
20:56 robotust1a prototype

21:14 rue_bed hmm'
21:15 zhanx Early to bed?
21:46 rue_house and early up!
21:53 anonnumberanon <rue_house> not managing tasks and crap, just doing one thing
21:53 anonnumberanon I have no idea why you are claiming this to be honest.
21:55 anonnumberanon My quadcopter managed motor control, AND remote control input.
21:58 rue_house thats its one task, it dosn't mutlitask so you can run a webbrowser on it too
