Hello,
given two quaternions Q1 = [Qx, Qy, Qz, Qw] and Q2 = [-Qx, -Qy, -Qz, -Qw], the resulting rotation is the same (but using an opposite axes and a reverse angle). So effectively Q1 == Q2

Re: MuJoCo Cable model not working
What happens if you use a different engine for the same scene? is it similar, worse, or better?

Re: Color detection using blobTo3dPosition sensor
Hello, the color (or the order of the blobs) is not relevant, since there is no blob order. Looking at the simVision.blobDetectionOnWorkImg function, you'll notice that for each blob, following will be returned: the blob relative size the blob orientation the blob relative position X the blob relati...

Re: How can I create my own path object through code?
Not sure I understand... you mean searching for "path" does not work?MarkusPelt03 wrote: ↑14 Mar 2024, 20:28...Other than that, how can I search for "path" in the forum if it ignores the search term? Thanks.

Re: Designing an Omnidirectional Mobile Robot: Confusion Arising from KUKA Omnirob Model
Only the wheel sphere dimensions are relevant: the insideSpheres are not respondable (i.e. they do not react to collisions), and thus only their mass and inertia matters.

Re: Ros2-CoppeliaSim and some bug.
Hello,
from the video, it looks like the joint gets target positions from two different sources. Best would be if you shared the scene file, so that we could have a closer look at it.

Re: Shortest distance
You can use sim.checkDistance(shapeHandle, dummyHandle), where dummyHandle is the handle of a dummy object located at the robot's reference frame.

Re: Designing an Omnidirectional Mobile Robot: Confusion Arising from KUKA Omnirob Model
A random mesh never performs well when a physics engine simulates it in collision response. The reason is that in order to be able to compute precise collision response forces, a penetration depth needs to be calculated between the two colliding objects. With random shapes, there is no such penetrat...

Re: connect python to the simulator's remote API
Hello,
make sure to use the newest CoppeliaSim version (i.e. V4.6) and the ZeroMQ remote API (instead of the legacy remote API, which is deprecated)
