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

Thanks, all woking well now. Am passing data into the joint object via a custom datablock, I have set things up so the datablock gets set by the script of the robot's body during the actuation simulation step. Then in the simulation's sensing step the joint object reads the custom datablock and upda...

Re: Signal 11 error on linux Mint MATE 19

This seems fixed in version 3.6, the Ubuntu 18.04 edition. Downloaded a copy a few minute ago, first time I tried to do "./vrep.sh" I got a signal 11 error again, but there was a helpful print statement just beforehand advising me to run "sudo apt install libgl1-mesa-dev". I installed libgl1-mesa-de...

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

Any more details on this, I can't see to find any clear tutorial telling me how to put a custom callback script onto a joint, even thought there is plenty of info about what the script should be like once it is there. Also, will using that script on the webpage, with thre addition of some sort of cu...

Making the floor "invisible" to proximity sensors

Ok, so in the real world I have a robot with a reflection based IR sensor, the stronger the intensity of modulated pulsed IR that comes back is the closer and/or largr an obstacle is. In the real world this sees the floor as a base level of reflection and I can recognise objects by seeing values gre...

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...
