can maplesim simulate a robot arm and hand catch a throwing ball and picking objects?

can maplesim simulate a balancing a robot legs?

will these simulation require complex formula to draw the robots arm and hand and maintain the joints stick together during motions?

can maplesim output the specification to autodesk for 3D print parts?

how much of a maplesim? 

i can not see the price in maple official site from Hong Kong area.

Dear Community,

I run a MapleSim model from Maple. The simulation runs fine giving me the correct graphical plots, but I wonder how could I obtain also the numerical values of the probes vs. time? Sorry I could not figure it out. A matrix format would be perfect: 1st column time, the other columns probe 1 .. n values vs. time. (Files attached)

Tx for the kind help in advance,

best regards

Hi,

I have to build a simple model in MapleSim that allows to simulate a mass that goes down along an inclined plane with a certain friction.

Is there a component that simulates the inclined plane? I tried to use a prismatic joint but it has some predifined translational directions so I can't impose the movement along the plane.

Hello,

I use MapleSim to model the dynamics of motorcycles.
I have been at MapleSim2018 for a few months and I have a problem of simplifying the equations generated by MapleSim from my model.
In MapleSim2018, he tells me:

Processing Equations...
SelectCompiler: Check for installed compiler successful
Simplifying system with 8919 equations
DSN/ix1lite: Warning, equation size increased past 100000 while performing equation simplification. Model will be simulated in partially unsimplified form
Simplification removed 8428 equations. Remaining equations: 491
Generating simulation code

 

the same model (exactly the same) in MapleSim2016, he tells me :

Processing Equations...
Simplifying system with 8942 equations
Simplification removed 8494 equations. Remaining equations: 448
Generating simulation code

When I generate code from two versions of Maple (2016 and 2018) and compile it into an executable, the MapleSim 2018 executable runs 20% slower than the MapleSim 2016 version of the executable (the results and the behavior of both models are equivalent)

It is very strange that a new version of MapleSim generates a slower code than the old version. it may be due to the limitation of DSN / ix1lite in MapleSim2018 ... while MapleSim2016 does not have this limitation (with more equations to simplify!).

I need help, if it is possible to activate the complete simplification in DSN / ix1lite?

it is a big problem for me, the use of MapleSim2018 is not possible because of that. My model does not pass in real time.

thanks.

I am trying to (again) extract the equations of the systems which have been done by me, but the equation extraction gave me wrong results.

 

For example;

The DC motor and the inverted pendulum equation must be 3. (third) order and only a differential equation.

The pneumatic motor and the inverted pendulum must be a differential equation (any order).

Also the hydraulic motor and the inverted pendulum must be a differential equation (any order).

 

I tried to use "isolate" command but it did not work for me in this case. How can I get the differential equations of the systems ?

 

I have added the MapleSim simulations and the differential equations that I had.

 

Please help me for this problem chain.

I need help for two exercise. In the first I have in the secondary circuit nothing, in the second exercise un inductor.thanksinduzione_fra_due_circuiti.msim



 

Thanks to Mr. Joe Riel, my previous problem is the port's name and the input signal's name was the same name was solved. It worked well in the new model but when I try to do exactly the same thing in my current model, the custom component can't be generated even if the "Check dimension" button shown that "no issues found". 

This time error is:
(in SetComponent) flattening error: Errors: Input length = 1
Error in Component btnGenComponent with the caption "Generate MapleSim Component"

Does anyone know from what this error "Input length = 1" happens? 

I am very appreciated for your help.

Hi everyone, I need to use the integral calculation in MapleSim but there is no MapleSim Block to do it. So I create a Custom Component and using the integral calculation from Maple, the expression of the equation was done. But when I click Dimension analysis button, one error popped out as the photo. Have anyone got the same error before? How should I do to solve it? Thank you very much.

I have training video that shows the visualization window "docked" below the main window.   Can this work space arrangement be done in sim2017 ??  

Also I push the anchor button and nothing seems to happen 

hi

by passing all steps to install Maplesim 2017.3 i confort the error "The system cannot find the file specidied" when i want to open it. what shoud i do?

I have modeled a 3D flexible manipulator in Maplesim. I intend to measure the torsional strain of the flexible beams. How can I do this??

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.,

please help me on check my schmitt2.msim schmitt's trigger 

I have an excel macro file (enable macro or save as macro and run) in which the colour of cells keep changing by a macro named macro2.

Can we achieve it in maple or maple sim?

Any one please suggest a way for me to try out.

I dragged into model space prismatic FixedFrame and RigidBody components and prismatic joint along y axis. I also set mass m = 1 kg. The manual says set K_S = K_S and K_K_d in inspector parameter setting. It did not work out. So i set values 12 and 0.1 for K_S and K_d. I sreated subsystem sub of rigidBody and followed the following instructions,

Quote" PrismaticJoint.PlacethePrismaticjointandRigidBodyinasubsystemcalledsub.Thisallowsthe EquationTemplatetogenerateequationsspecificallyfortheselectedsubsystem.
3. ClickTemplates( )intheMainToolbarandselecttheEquationstemplate. 4. IntheAttachmentfield,provideaworksheetnameandclickCreateAttachment.Your MapleSimmodelopensinaMapleworksheet,withtheSubsystemSelectionwindow.

ClickLoadSelectedSubsystem.Thesubcomponentparameterandvariablesload automaticallyintheParameterandVariableManipulationareas"

After this i wanted to modify the equations. I could not. The same equation is reassigned.

Parameter and variable rows - are as shown in manual, but a blank row not available for user's use. But how do i get the variable x(t) there and rename it?

Thanks for an example of this chapter with an application of its use., if available with anyone?
