#robotics Logs

Feb 28 2015

02:43 profil I am searching for a communication protocol to implement between several robots and a server over TCP
02:44 profil does such a protocol exist or should I just implement my own? (I am thinking something very simple, text, like IRC or something)
03:24 RifRaf i2c?
03:31 profil i²c over tcp? wut
03:33 RifRaf sorry, was more about a suitable protocol, not tcp related
05:07 veverak profil: json structures?
05:07 veverak profil: P.S: of course based on TLS
11:25 rue_more profil,
11:25 rue_more I have some code that just does text back and forth on port 77
11:46 rue_more I use it for my home automation
11:46 rue_more there is a message server a number of apps connect to pass messages around
11:47 rue_more doorbell event, turn on message waiting light, turn heat on/off
11:47 rue_more water plant
15:56 Loshki profil: I think some if it depends on what you want the robots do to & what they will be talking about. Do you have any idea of the *content* of the messages yet?
21:03 rue_shop3 making a gear library, 6 to 20 teeth
21:03 rue_shop3 seems to work nicely
21:09 Jak_o_Shadows 3d printed?
21:10 rue_shop3 yup
21:10 Jak_o_Shadows Just normal spur gear?
21:10 rue_shop3 they are generated in inkscape, so they aren't really super gears
21:11 rue_shop3 yup
21:11 Jak_o_Shadows I oughta print some of the gear bits for the base of the robot arm
21:12 rue_shop3 did you see how I did mine?
21:12 Jak_o_Shadows on what arm :P
21:12 Jak_o_Shadows I've seen some
21:12 rue_shop3 arm8 ish
21:12 Tom_itx rue_shop3, like you don't have enough gears already!
21:13 rue_shop3 yea, but getting a particular ratio is an issue
22:33 Triffid_Hunter rue_shop3: fwiw openscad has an involute gear script in the MCAD library
22:41 rue_shop3 ?
22:41 rue_shop3 oh
22:55 Jak_o_Shadows I wonder if inventor does gears nicely...
22:57 slidercrank do you buy wheels or make them yourselves or 3D print them? what about cross axles?
23:09 rue_shop3 I go to the box of wheels
23:09 rue_shop3 axles come from the rod stock
23:10 rue_shop3 lots of 8mm
23:10 Jak_o_Shadows I too have a box of wheels
23:30 rue_shop3 I wonder if I'll ever use up all my wheels
23:30 rue_shop3 I suppose the idea is not too
23:30 rue_shop3 there is a box to provide selection
