State variable'diff(diff(`Main.R41.theta`(t),t),t)' does not appear in dynamic or constraint equations.

I am trying to model a parallel manipulator but I am receiving an error message

State variable'diff(diff(`Main.R41.theta`(t),t),t)' does not appear in dynamic or constraint equations.

I tried changing the Revolute joint 41 but the same error is repeated.

You can find my model here: ParalelManipulator_v2.msim

Can you help me solve this issue? Thank you in advance!

MapleSim Parallel Manipulator Error with the model

uomcsg — Mon, 06 Nov 2017 03:59:15 Z

Hello everyone,

I have modeled a parallel manipulator using MapleSim 6.4 and it is giving me an error.

ParalelManipulator_v2.msim

The types of joint are shown by the visual below. Note that in my model I have used a universal joint or two coinciding revolute joints instead of a speherical joint.

MapleSim Probe Windows do not appear

I have recently reinstalled the MapleSim 6.4 but the probe windows do not appeaar anymore.

The image below shows that there are 3 probes (none are disabled) and when I run the simulation nothing happens.,

How do I solve this problem in MapleSim?

Hi, i don't know what happened but every time that I run the simulation appears this:

invalid input: Multibody:-GetMultibodyData expects its 4th argument, lsProbes, to be of type list(list), but received registerMultibodyVariable

If anyone can solve this problem, I am going to be very grateful. Thanks

MapleSim: Point to plane contact

uomcsg — Mon, 13 Feb 2017 11:47:36 Z

Hello everyone,

I am making a mobile robot simulation in the MapleSim environment and I need to create varriable (uneven) terrain, do I need an additional library for that?

If not how can I do so?

Thanks for your time!

MapleSim: Custom Component - How can I find min between three values ?

uomcsg — Mon, 06 Feb 2017 01:23:55 Z

Hello everyone,

I am trying to create a custom component to find the minimum between 3 values.

I know that in Maple it is done by:

l := [5, 2, 3];
min(l[1], l[2], l[3]);

However I could not do the same with a custom component. I provided a screenshot below, where h(1), h(2), and h(3) are my input values and min(h1,h2,h3) is my output.

Thanks in advance,
