Hi All 
I have been playing with the idea of building a hexapod or 
Stuart platform mill with linuxcnc for the control system. 
What I need help with at this stage is the design of the joints and 
length of the struts. I have a few designs in my head and sketched out 
on paper and am looking to see if any one knows of a program i could use 
to test various geometries before I started cutting metal and building 
100 small test models. This way at least I could get a rough estimate of 
the expected work envelope and length of various components to do 
further computer testing and modelling before committing to metal. 
I have played a little in with blender but this is such a big 
program with a steep learning curve geared more to animation. It has to 
look right not be true in a mechanical sense. Any hints or suggestions 
will be greatly appreciated. 

Thanks, 

linden

Linden, 

I'd probably start with Matlab or the open source version, Octave, to work out 
the kinematics. These numerical packages have some pretty powerful plotting and 
visualization tools that can be driven by numerical functions of your choosing. 

Once you work out the basic geometry l'd move to Solid works, FreeCAD or 
Solvespace to work out the component geometry.

I wonder if there is anything like

That's almost all you need, but in 3D.

Googling suggests that there is a library for SciLab, but that might
be purely serial, not parallel.

a 3d version of that game and I'd be stuck in front of the computer for 
days. lol

I have found this too just need some time to invest to figure out how it 
works but still looking for an easer solution.

onshape looks good if only i had a decent internet

Linden,

Onshape (a web-based CAD tool) will let you link struts together and
simulate movement.  It's not able to script movement yet, but pushing
struts around with the mouse will reveal your rough estimate of work
envelope faster than a physical model.  It's also pretty easy to learn -
they have a lot of video tutorials for impatient amateurs like me.

CAD (Cardboard Aided Design) is considerably less expensive than 
starting out with cutting metal. ;) Many interesting mechanical things 
have first been worked out using pieces of wood, cardboard and a hot 
glue gun.

2015-10-24 Thread linden 
@ Gregg drinking straws and pins seem to get a lot of use around here 
;-) along with the cardboard

I have modelled a lot of the parts in freecad already Just having issues 
with the assembly and animation apart from that it is wonderful and 
evolving so quickly if things keep up at the current pace in 5 or 10 
years it will give solid works and Autodesk inverter a run for there 
money.  Just hope it dosen't run out of steam before then.

@N. Christopher Perry

Solvespace is new to me it looks promising for checking and plotting 
motion. I have downloaded it today and will play a little at first 
glance it looks like it only dose 2d motion but it is a good start.

@ Alex

Something like Onshape sounds like what I am looking for I will have to 
try when I have a decent internet connection

Thanks again for you input and suggestions once I have something fit for 
general consumption I will share my model if any one is interested.
