#robotics Calendar

03:11 AM Jak_o_Shadows: ok.
03:15 AM Jak_o_Shadows: after trying out some power supplies (including a truly terrible battery charger that had no smoothing at all, just rectificatiion!), I think the problem with the christmas lights here is that the power supply is terrible
03:55 AM LuminaxWk is now known as Luminax
10:29 AM rue_bed: k
12:20 PM durrns: https://www.youtube.com/watch?v=nGynmnMUuMg far from perfect but it walks!
12:24 PM rue_shop3: ouch, did you kill a servo there?
12:24 PM rue_shop3: nice tho!
12:24 PM durrns: no it does that at that point of the scripted walk for some reason
12:24 PM rue_shop3: looks like you need to rework your offsets eh?
12:24 PM durrns: yeah
12:24 PM durrns: lmao
12:25 PM rue_shop3: I recognize your last leg link there...
12:25 PM rue_shop3: http://ruemohr.org/~ircjunk/robots/frankenhex/p1090368.jpg
12:26 PM durrns: its from thingiverse :/
12:26 PM rue_shop3: yea
12:26 PM rue_shop3: I traced it back when I was looking thru thingiverse
12:26 PM rue_shop3: the origional author never finished his project
12:26 PM rue_shop3: but EVERYONE liked that leg segment
12:27 PM rue_shop3: http://ruemohr.org/~ircjunk/robots/frankenhex/p1090284.jpg
12:27 PM rue_shop3: I had to make the generic backcaps for the servos too
12:28 PM rue_shop3: I was going to just cobble togethor a whole robot out of different robot parts on thingiverse
12:28 PM rue_shop3: after that first leg segment, I had to design the rest
12:28 PM rue_shop3: http://ruemohr.org/~ircjunk/robots/frankenhex/p1090273.jpg
12:29 PM rue_shop3: it was an interesting project cause I more-or-less printed all the parts, put them in a bucket, and then assembled them
12:29 PM rue_shop3: it was totally an ikea experience
12:29 PM rue_shop3: missing two of these, and why do I have so many of those?
12:30 PM rue_shop3: http://ruemohr.org/~ircjunk/robots/frankenhex/p1090217.jpg
12:30 PM rue_shop3: I need to finish it (software) sometime
12:30 PM rue_shop3: http://ruemohr.org/~ircjunk/robots/frankenhex/p1090207.jpg
12:30 PM rue_shop3: I did assembly a 24 channel servo controller, stm32 based
12:31 PM rue_shop3: http://ruemohr.org/~ircjunk/robots/frankenhex/p1090368.jpg
12:32 PM durrns: yeah, next step is to make the electronics smaller
12:32 PM durrns: lol
12:33 PM durrns: theres a lot of resources out there, but many projects seem to be mostly complete but not quite complete
12:33 PM rue_shop3: yup
12:33 PM rue_shop3: I can testify to that
12:34 PM rue_shop3: http://ruemohr.org/~ircjunk/robots/buddy_III/p1050598.jpg
12:34 PM durrns: i just wanted to work on a tiny but of stuff and i wound up making it walk today, not bad for a project i started over a year ago
12:34 PM rue_shop3: http://ruemohr.org/~ircjunk/robots/buddy_III/p1020058.jpg
12:35 PM rue_shop3: that was started in ....
12:35 PM rue_shop3: 2002?
12:35 PM rue_shop3: I should check the batteries again
12:35 PM durrns: what hurdle is preventing you from continuing it
12:36 PM rue_shop3: well, to keep from stripping the gearboxes, each leg has an overload circuit
12:36 PM rue_shop3: a FAST one
12:36 PM rue_shop3: too fast, it trips in 1 pwm pulse
12:36 PM rue_shop3: so I have to redo them
12:37 PM rue_shop3: 6 overload boards
12:38 PM rue_shop3: it limits each leg to 1A, and trips out the whole leg if anyone goes over
01:44 PM rue_shop3: ok I made a tiny13 based serial controlled pwm gen
05:39 PM SpeedEvil: https://imgur.com/gallery/O2xpqrz Well - that's the non-robotic way to do it.
05:41 PM rue_mohr: aaahahahahaha
05:48 PM Tom_L: whole new meaning to 'trojan horse'
05:54 PM patr0clus is now known as s3nd1v0g1us

06:33 PM robotustra: do you know him?
06:35 PM Tom_L: no
06:41 PM Tom_L: just an observation
06:48 PM robotustra: where is rue's mecha?
06:49 PM Tom_L: in canada

07:04 PM Tom_L: there's his big one
07:18 PM robotustra: I think will grow even longer hairs by the end of this build
08:31 PM rue_mohr: :)
08:32 PM rue_mohr: one of the guys i know is making a mech thing for haloween, gonna see if I can wrap some of the sparrow1 stuff in and give him and hand
