did you guys know that hexapod is trademarked?
" Trade Mark Notice: All trademarks acknowledged. According to Geodetic Technology they have obtained trademark number 2153930 for the use of the term 'hexapod' in a machine tool context"
US I think
do you know how long ago?

yep - UK - googled
that looks like a low number, but I can't be sure.
they can't trademark it if it's been in general use beforehand
(but then there's Windows, so what do I know?)

does this mean you cannot use the term hexapod for robots any longer ?
LOL UK located in Texas.... Brits would be so lucky!
I was only kidding
how goes it?
sri... was watching the news .... was an interesting day with all the brains online!
pretty funny... there was a gay pride parade in Vancouver today... some pretty wild pictures
not really, we have theat here every year =)
a good excuse to run wild in your underwear... they had a couple of Nuns flaunting their stuff
San Francisco Gay Pride PArade
I prefer club med myself!
I gotta make it up to the next one early enough - with camera in hand
I probably need more cF cards too
I finally found a circuit for a constant current source for unipolar steppers....
making your own driver huh? microstepping?
[02:50:49] <LawrenceG> http://pminmo.com/3axis/3axis.htm
actually I was looking to adapt it to driving servos as a current limited drive
oh, needs big old fat resistors
check down a little lower.. that is the chopper to eliminate the big fat resistors

I remember seeing the site a ways back.
someone posted it today and I just happened to look through it.... some of the stuff is a little questionable but most web stuff needs a little sanity check... good for ideas
ideas are good =)
the web has so many ideas available it is hard to get anything done!
according to the emails I have been getting I must have won just about every lottery in europe
dont forget my 10%
I need my bank manager to figure out how to empty their bank account!
are you having good weather down there?
Yeah, warm too. I got the A/C on in here atm, but this room gets hot all year long.
It's takeing FOREVER to index these images!
we are right on the edge of a front at the moment.... was clody and sunny all day... not rain, but we may get some tonight
no rain in site here
Eeeesh, at this rate it'll take me another two days to finish this up!
hey all... long time no c
03jmkasunich * 10emc2/src/emc/ (5 files in 2 dirs):
Added hooks to allow halscope to look at trajectory planner internals for
debugging. Also added some prints in an attempt to understand the code. The
prints and HAL hooks are temporary and will be removed later. Also revised and
added comments elsewhere.
how's things going?
* anonimasu just woke up
well 1 hour ago..
I woke up a while ago
I am still on my way to work ;)
been reading about hal..
I am at work.. but.. I yearn for my bed
curious about a USC driver
write one :P
why else would I look at hal ;)
* alex_joni starts his devel box
not that hard.. (an USC HAL driver)
hal does not seem that complex
nah.. it's fairly easy
at least to work with it
I think the board will arrive today :
I realized I can use the 4th axis as jog wheel input
if I'd like..
[08:18:13] <anonimasu> http://www.pico-systems.com/univstep_regs.html
you can use the parport for connecting an encoder to it
I dont know if it'll be fast enough
ah but it does not really matter if I cant get the machine to move
I'll have a look at emc1 to see how they control the card there
hm time to go to work.. I'll be back from there instead
* anonimasu is making backups
wanna see smthg nice?
[09:03:52] <alex_joni> http://www.robocoaster.com/english/index2.html
*longs back home to bed*
I didnt get to finish my cup of tea :/
I am dead tired..
I read lots of that sonia paper yesterday :D
it's pretty ok
it probably sucked the life out of me that's why I am tired today ;)
but today is a good day for coding
I might agree
I've gotten lots of stuff done already
if this keeps up I'll have the memory hack implemented by afternoon..
I am happy this language supports encapsulation of objects..
otherwise I'd have 6900 memory objects..
now I have 1 memory object per settings..
that contains 10 variables all their own object within..
[09:39:52] <anonimasu> http://www.laas.fr/~jpl/book-toc.html
not what emc needs
this is path planning
for mobile robots
looking at the colission detection stuff
try this: http://robotics.jpl.nasa.gov/people/volpe/papers/icra93.pdf
way over my head probably
that apper seems nice also
will print it also :)
when you do 3d trajectory planning the only difference is that you limit the maximum acceelration/velocity of the faster axis:es to cope with the max speed of the slowest one right?
and then you calc acceleration/velocity for all 3 axis:es and you have interpolated motion
smthg like that
hm, tp calculates velocity vectors and tc takes care of calculation the velocity and acceleration
hey there Jacky^
what's happened here the last few days? anything exciting?
yestarday was an interesting meeting here, a lot of peoples
dam and i missed it
i HATE my cap
see the topic
are you working to build your machine ?
in the planning phase
i think i know what i want... but i'm not sure :)
stepper or servo ?
probibly stepper... cant afford servo's
hehe, i'm too..
how big a cutting area?
just for testing
* Yuga should also start with something small.. but!!!! i never do anything small
i will learn as i break stuff :)
can you build the controllers from yourself ?
nopes. buying those gecko ones
ah, nice, gecko are very good, they said
yep... thats what they say :)
so, youre waiting to get gecko controllers
waiting till i have finalized my plan
and need to work out a budget
you could try some experiment using a small IC uln2003 and some recycled stepper from an old printer..
to learn how emc work
the hard thing is to setup the ini file to work properly..
yes... heard many ppl say that before
u messed around with it yet?
