Title: Running the Kinematics Simulation
Post by: XusmX on April 05, 2018, 08:34:39 PM
I am new and have installed Gearotic 3. I am having a problem finding/loading the Kinematic s Simulatio n. Can someone tell me how to find and start this applicati on?

I found the instructi ons in the comments in one of the YouTube videos.

"Kinematic s is inside Auggie. You can run it by modifying your propertie s so that Auggie is run with -con as a parameter . (Or run Auggie and press the CON buttton on the cnc screen.). Vexx doesnt yet have any kinematic s.?"

Hi:

 No, sorry, although I started Vexx to make kinematic s better, I havent yet
gotten to a spot where Im ready to add them. Vexx is still building its capabilit ies
until I reach a bit further at which time Ill start adding kinematic s with a better interface .

Thx

First time poster here - not to bring up an old post, but I think this one is relevant to what I'm looking for.  I've done a lot of reading on the forum/new website/tutorial videos and starting playing around with the software this weekend to see if it can do what I'm really looking for...

I am digging the gear making aspect of gearotic, but I was wondering if there's a streamlin ed path to taking some of the ratchets, gear, etc., and combining them with some kinetic art shaped items to simulate the effects of gravity as a whole with those arms plus springs on the drive arms.  These are items I would be creating in another program like Solidwork s or something so I am looking to import via DXF or otherwise .

I was able to do some funky testing in Auggie with the gravity, but I didn't see anything like that in Vexx.  Did I miss that somewhere?

In short, I am trying to virtually build some kinematic pieces from various sources (or I could draw the arms in Vexx if necessary) and see if I can simulate a run time/visual effect.

Or is what I'm looking to do just not something this software package is built for?  This seems to be the closest thing I've found so far that is made for kinematic simulatio ns.

Thanks in advance,

Jason

Jason:

  Im afraid Vexx just isn't there yet. I havent added any physics engine code to it
and Im not sure when or if that will be done at this point. I keep adding toys to Vexx
over time , but Im not sure its methods for grouping are yet built up enough for
adding in the physics needed to do what Auggie does in its test engine.

 It isnt a closed project though, I am actively still researchi ng what exactly I can add
to the variety of software out there that would be a good fit for Vexx in terms
of simulatio n..

 But as of now, Its likely not enough for accurate simulatio n, the best you can do is draw
up tests in Auggie that are simple enough for it to run...

Although Vexx has not evolved to include the physics portion of the Augie Simulator, that does not mean you can not create a fairly complicat ed simulatio n.  It takes hours of work, practice, and patience.

In the creation of my kinematic simulatio ns I used a combinati on of gearotics<-->Vexx<-->Augie vector processor .

The "motion works" kinematic simulatio n involved taking a gearotics simulatio n of a clock's motion works that I had created a couple of years ago.  I used Vexx to get the gears from the gearotics simulatio n to create a collectio n of appropria te DXF files which were then imported into the Augie vector processor . The gears were fixed to the backgroun d in the first kinematic s model.  A second model was created based on the first model except this time the motion works were attached to a moving frame that crawled along a toothed rack. This helped me learn the technique s needed to make a moving object.

My "walking man" kinematic simulatio n was based on lessons learned from the moving motion works model. The man's component s were drawn using Vexx exported as DXF's and then imported into the Augie vector processor .

The "mech" feature of the Augie vector processor allows you to build/test component s & then assemble a more complicat ed object by importing the mech files.

I decided to simulate pendulum clock as a learning experimen t of how the vector processor simulates gravity ( " A combined gravity escapemen t / motion works" model).  The gravity escapemen t was created using Vexx.  Once the model was working correctly, I added in the motion works model.

These models were published mostly under the Mechs and Kinematic s topic area of the forum.
