Re: Joint torque seems insufficient

This is probaboly a physics engine problem due to having too low a mass and/or moment of inertia on some of your parts, the physics engine then doesn't properly makew these move when you try to turn them slowly, however high your torque may be. You might also find joints floating off axis as another...

Re: Changing the speed of a "servo" from within child script

Ok, so I set a custom joint callback script and paste the contents of that webpage into it. I'm assuming that at that point what I'll have is a joint which has a cutom callback script but behaves exactly like the normal position control mode of a joint. Then how do I allow the child script on the jo...

Changing the speed of a "servo" from within child script

I have a revolute joint in Torque/force mode, position is not cyclic and position has limits with a range of 180 degrees using -90 degrees as Pos.min.[deg] . Motor is enabeld in dynamic properties, a max torque is set and control loop is enabled. In my child script I need to set the position to move...

Re: Hexapod

Can you not remodel the non-convex object as a group of several convex ones?

Re: Signal 11 error on linux Mint MATE 19

I think Mint 19 is Ubuntu 18.04 based, so that would explain my trouble. I'd give a good guess that if V-REP ran on ubuntu 18.04 it would probably cope on Mint 19 to (they are very smilar distros). Do you expect V-REP 3.6 to be ubuntu 18.04 compatible? As well as preserving compatibility with Ubuntu...

Re: Signal 11 error on linux Mint MATE 19

EDIT: I've tried V-REP 3.4.0 (previous version) on this PC, it opens up alright and runs a few simple simulations ok. This issue is clearly related to a change made to V-REP between version 3.4.0 and version 3.5.0*. As all my files I need to work on here made in 3.5 though i get serialisation warnin...

Signal 11 error on linux Mint MATE 19

I've got linux mint mate 19 newly installed on a PC and have tried to install V-REP. It crashes upon startup and prints the below error message into the terminal. robert@robert-HP-PC:~/V-REP_PRO_EDU_V3_5_0_Linux$ ./vrep.sh Using the default Lua library. Loaded the video compression library. Add-on s...

Re: Repeatable seeded pseudorandomness

Just to check, will there be a way to set a seed for the whole scene, then even if multiple identical robots are all running the same controller they won't all get the same sequence of random numbers? Will there also be other options to have a separate randomness source and separate randomseed on ea...

Re: Repeatable seeded pseudorandomness

Thank you for that, any idea when the new version of V-REP with this feature will be released? P.S. I'm assuming you'll do all you can to maintain compatibility of scripts and models between the current version and that next one. I'd hate to have to redefine all my geometry, actuators and custom sen...

Repeatable seeded pseudorandomness

If one wants to insert deliberate randomness into a simulation using (for example) CompassAngleToDriveAlong=math.random(-180,180) but one wants the series of directions chosen by this function to be random but repeatable then in lua one would typically set math.randomseed(KnownConstantValue) beforeh...
