Re: preferred joint movement

Perfect ! Thanks

Tried it with a change from 1.0 to 0.5 but seeing that it didn't change anything did not try smaller values! With 0.01 it looks like what I want.

preferred joint movement

Hi
in my model I have a Spherical_Basis and 3 revolute joints. When I run the simulation the Spherical_Basis rotates around the z-axis. I need however a rotation of the revolute joints in order to avoid the collisions of the <x>2 elements. The <x>2 elements will then need to be shortend.
I could not ...

Re: no attachment to inverse kinematic points

HI
With the working scene back in place I tried now to follow your other tipps about manipulating the table and record the Revolute Joint degrees.
I have been told to do the scripting in a custom child script in the initialization section.
I have also been told to use explicit handling for the child ...

no attachment to inverse kinematic points

Hi

I can't really see why my dummies LC_VUGruen, LC_VUGelb and LC_VUWeiss are not connecting with their according fixed Points. So instead of getting a fixed table position the table spins around its Spherical Base.

Any idea what's wrong with my scene?

Re: tutorial inverse kinematic

Hi
Real progress now and Mark Freese has already followed your instructions and sent me an updated version.
I hope I am not exausting your patience - after setting all IK-Groups to DLS I have now a stable simulation - however I can't move the table - or do I have a mouse control problem?

Re: tutorial inverse kinematic

hi
thanks - tried to look at my details and fix things.
could you please explain why you consider my construction overconstrained and what is causing the horizontal holding position?
I expected that by applying different forces to the motors the "table" should move away from the strongest arm?

Re: tutorial inverse kinematic

hi
thanks for your input - I still can't see how to get a "ServoTable" that responds to my mouse movements.
I have set the Basis shape to not responding.
I have also set all revolute joins to inverse kinematic hybrid.
There will be motors in the implementation for the revolute joints magenta, blau ...

Re: tutorial inverse kinematic

Hi

I am most certainly happy to share my little example https://drive.google.com/folderview?id=0BzHOAcGHjhpTcDhhYkUxa3Vjc2c&usp=sharing

I might currently have quite some "funny" settings as I worked a while on it. My intention is to be able to move the "middle table" or the Sphere and record the ...

tutorial inverse kinematic

Hi

After trying to follow the inverse kinematic turorial where all joints are in inverse kinematic mode I tried to build my on structure in a similar way - however - my joints get ignored in the simulation and everythings falls apart according to gravity (and manual).

I have not been able to ...

Modifying shapes best way

Hi

I have created a simplified model of a basic robot part and want to experiment with different part length and sizes.
I have created connecting elements with 3 cuboids - end cuboids for positioning the joints and a middle part connecting them.
As the grouped element got positioned and rotated I ...
