The side boxes are frictionless. In "Tool Test - M8 Nut.xml" they are making only sporadically contacts with the thread: time dzpos turn...
The file is "Meshes\M8 thread segment 2.stl". All STL files including the OpenSCAD sources have been uploaded to the forum's resources section....
A task for a humanoid robot. It is assumed that the robot has already been trained to recognize, want, grasp, and eat cookies. Mapping reward to...
The demonstration video has 210 Mb, that's too large to upload here. It can be downloaded from Google drive at...
A timestep of 0.5 ms is enough to simulate hard steel-on-steel contacts. The solver is not the problem. It's a bug in the mesh collider that makes...
Single point contacts plus zero sized gaps between adjacent meshes are the modelers nightmare. If you're lucky, the contype/conaffinity mechanism...
When modeling, most time is spent in the editor and HAPTIX stays in background. Although there is nothing to do, HAPTIX 1.31 still consumes 9% of...
Isn't njmax=1000 the default setting in HAPTIX 1.31? It spreads its log file in every current directory, and there it complains about array bounds...
Well, I was just moving the beam around trying to find its position so that the beams don't collide and stabilize the thread segments at the...
The balls remain in their bowls for 25 seconds when condim is 3. [IMG] They immediately fall through when condim is 1.
This model file causes Haptix 1.31 to crash. It runs into an int3 instruction in Kernel32.dll. If I replace the -1 at line 33 column 113 by -.55,...
I've spent the last few years reading scientific papers about A.I. and robotics. In 2009, I took my game-benchmarks-with-vision suite offline and...
Yes! The angvel trick did it! [IMG] The orientation of the blue box with the thread can be changed with the two control sliders in the F3...
Another idea. If the orthogonal 3x3 matrix contains the Z axis from the model file as the 3rd column, then it probably contains the X and Y axes...
The conversion from quaternion to Euler was a bad idea. If even the experts don't get it right, then how should a mathematical laymen?...
An idea: I could try http://www.euclideanspace.com/maths/geometry/rotations/conversions/quaternionToEuler/ and the needed angle should be the...
Yes! That's it! The third column of the matrix is exactly the z_axis from the XML file that I was looking for. Thank you very much! The program...
You don't know Intel C++ 9.1... This was a replacement for Visual C++ 2005 which created somewhat faster executables. Its error messages were so...
An axis and a rotation angle seems to be what I need, so I don't have to care about Euler angles any more. Unfortunately, there is the little word...
I want to rotate a nut around its original Z axis. The nut is a free floating object and can have any orientation in space. mj_get_onebody()...
