Set dynamic mass from C++ plugin

Hello everyone, I have a simple question: is there a way to set a dynamic mass in V-REP from a C++ plugin? I explain my problem better: I want that, while the simulation in running, the mass of a respondable object changes over time (with a certain timing law I decide). I tried with simSetShapeMassA...

Re: Building new robot in Vrep

Just a question (maybe a little bit stupid but this is my 11th hour of work today): - why do I have to add a non-pure shape for the visual effect? I mean, why not another pure-shape (if it is faster, maybe static)? I understand the usage of double structure (pure for dynamic calculation) and non-pur...

Re: Building new robot in Vrep

Thank you for your response. I will try your suggestion and check if it works. I do not want to disturb you with downloading my file. By the way, what I did is: cylinder (respondable - pure shape) - cylinder (non respondable - non pure shape - static) [This is where I put my mesh in the future] -- f...

Re: Building new robot in Vrep

My idea is to create for each link one pure-shape (really simple shapes) and then another non-pure shape (as child of the pure shape) for the visual effect (static and non respondable). For this reason I attached the force sensor. What about the collision problem? Do you suggest to edit the shape wi...

Building new robot in Vrep

Hello, I'm trying to build my own robot in Vrep. I read the tutorials and I see that the best way to do that is to create a double-layer system. Each object of the scene is composed by: 1) pure shape (that is respondable and not visible - layer 9) 2) non-pure shape for visual effect (I guess I can s...

Hot to compile plugin

Hello, I got the new version of 'import URDF' module (as plugin example) but I faced some problem in how to generate the .so to put in the main folder. I found a solution but I'm not sure it is the direct one. Then I would like to know the 'official' procedure. In that way, other users can also use ...

Re: Grasping metric

Hello,

thanks for your response. If it is possible, is there any metric? I mean to measure the grasp quality (i.e. not only grasp/non grasp but also a metric) such as force closure?

As alternative, can I import an algorithm in V-rep? Do you suggest as LUA script or as plugin?

Thank you,

Neostek

Grasping metric

I saw that a robot in V-rep could grasp an object (like in MTB tutorial example). I want to ask you if some metrics of the grasping are available, i.e. a measure of the quality of the grasp (e.g. force closure). I have to develop a grasping algorithm and a measure is really important for me. As nega...

Re: Disable dynamic engine for motion planning

Thank you for your responce. I think the best option is the second one since when the robot finishes to plan, it has to run the algorithm it found. In this new step, I need dynamics. So it is what I was looking for. Thank you again,

Re: Disable dynamic engine for motion planning

I answer to the question by myself and I write here the solution for others that wants to know the same. It is really simple. Just go to
calculation module panel (f(x) symbol)-> dynamics -> uncheck dynamics enabled

Best regards,
