[Emc-users] CNC Plasma Tube Notcher

Hello all, Some of the videos linked in the "LCNC TED Talk style" thread reminded me of a CNC plasma tubing notcher I designed and built a few years ago while I was in school. I think some of you might be interested. As built the notcher has a capacity of 4". It consists of a rotating

Certainly no one today would get a Phd for writing a CNC controller. But I would not be surprised at all if he did not need to do a considerable amount of work involving motion planning if he was working with statically unstable walking robots. Likely some of that work found it's way in to a CNC

good ... about axis number is for 2 arm robot ... not planning to partecipate to darpa race (for these year ;)) ... the pose number is more hight then world axis ... and actual axis number in g code, for 2 arm robot (18 axis) I think is quite good, because most part of work is on pose flag not in

Re: [Emc-users] max joint number

You are right. It takes 12 numbers to specify the location the orientation of two arms. But in a typical robot there will be more than 12 axis. If you look at the stat of the art, there could be 100+ axis, see below. With a typical robot the number of axis may not equal the number of degrees

G Code is just a symbolic way to represent something in a human readable manner. Another method could be used and would seem difficult for the humans to comprehend. On Thu, Jun 15, 2017 at 4:07 AM, andy pugh wrote: > On 15 June 2017 at 08:08, theman whosoldtheworld

[Emc-users] max joint number

there are some possibility that the max joint/axis number become more than 0-8 in future? (0-17 / 0-26 ) Actually if I well undertand is possible use makinekit fork with multiple machinekit instance on same pc ... so same pc more than 0-8 joint ... but I investigate other possbility. bkt
