Re: Slotting pin into hole only works when I scale up by 4

In the end I fixed this. It seems that by using some simplified versions of the meshes, and then making them into compound groups of convex shapes rather than random shapes this fixed itself completely. My pins now slide into the holes perfectly and seem pretty stable over the long term, no weird vi...

Re: Changing multiple colours at once

Could you please give an example of the syntax used for that command, I'm just not entirely sure how you specify the various elements of it. Also, where is that command run from? I've written basic lua controllers for robots in V-REP, non-threaded child scripts I think, but I'm not sure how to run c...

Re: Strange problem with objects slipping out of place, what am I doing wrong?

I've realised that most of my parts are really tiny, and very low mass, as the real robot parts are. I'm going to have a go at changing the internal scaling, perhaps using full scaling, of the physics engine. If that fails I'll try just making up some fictionally high masses and seeing if that impro...

Strange problem with objects slipping out of place, what am I doing wrong?

I've been trying to simulate a robot with quite a lot of joints (all in force/torque mode) and plenty of compound convex shapes (all dynamic and respondable except a few which are static+non-respondable and used as visual covers for the blockier dynamic/respondable shapes in hidden layers). Right no...

Changing multiple colours at once

When editing "appearance of compund shapes" one finds a compoiund shape as a collection of sub shapes, and sees the "Edition of Compund Shapes" dialog box with opotions such as "adjust colour". I have some compund shapes with about 40 shape components to them. I really do not want to have to edit a ...

Re: Slotting pin into hole only works when I scale up by 4

Thanks for the tips. I'm not sure if that strategy with dummies would be appropriate though, would it not end up with one robot effectively becoming parent to the other? As for giving up on random meshes there might be a way this could work, if the dummies system forces parenting and becomes inappro...

Re: What slows V-REP most?

Thanks for those tips,
P.S. any idea about the video rendering thing I mentioned in my post at the start of this topic, is there a way to get videos to be made (however long the making actually takes as depending on the processing power of one's PC) so they play at what would be the real speed?

Thanks for clarifying that, foolish of me not to notice the option under "file".

What slows V-REP most?

I've been trying to work out which features in a scene slow V-REP the most. I wondered if I could have some clarification on which of these things I've noticed typically have the greatest slowing effect when large numbers of robots are operating together in a scene, my study focuses on modular and s...

Is it not possible to import obj/stl files in V-REP on ubuntu?

I've downloaded V-REP (Edu version, v3.4.0, downloaded as the latest available version last week) onto my ubuntu (16.04 LTS I think and can check if it helps) system. I've been having a go at defining custom robots after spending some time reading through various tutorials in V-REP's documentation. ...
