Re: Car Simulation

Does that model still exist anywhere? I'm trying to implement a very basic simulation of a wheeled vehicle with front wheel sterring, rear wheel drive and a really crude approximation of a differential gearbox, I can see that the manta car model has it buty in that model the details of steering and ...

Re: Tutorial on creating automatic V-REP simulations for statistical studies

Are you effectively saying to write a bash (I'm on a linux PC) script to start V-REP, run my sim, then close V-REP then start V-REP up again with new parameters fed in? Wouldn't that be quite slow, V-REP always takes several seconds between me pressing "enter" at the command line after ./vrep.sh and...

Tutorial on creating automatic V-REP simulations for statistical studies

I need to run a large number of V-REP simulations for similar scenarios but with some starting parameters slightly varied for each. I need to do this both in cases of randomly varied (within defined limits) parameters and other cases where I will need to try a simulation with a certain parameter, th...

Sending integers as custom datablocks

I'm using custom datablocks in quite a lot of ways to transfer information between models to both carry communications and say things like "you are in range of my sensor". But in some cases I only need to send really basic information across, in some cases all I need is for one object's child script...

Re: Controlling Joints in a Flexible robot with V-rep

I think you might need to change settings on your google drive link, it doesn't seem to open. You might have left on a setting such as "private only I can access".

Re: Making wheeled vehicles with kinematics and no dynamics?

I might be able to post one, but I've already isolated the source of slowness to within that child script. If it the 28 copies of it are deleted from the 28 proximity sensor objects which they are on then the sim speeds up by a factor of about 3. Can you advise what, amongst that script, is the thin...

Re: Making wheeled vehicles with kinematics and no dynamics?

I've found what is slowing me down. I had a go at disabling the script which writes to dummies depending on whether they are illuminated in the cones of LEDs (proximity sensors act as these cones in the sim). My sim now runs in 48 secs rather than 2min 17, a great improvement. I've attached the cont...

Re: Making wheeled vehicles with kinematics and no dynamics?

Ok, I've tried removing all my barrels and adding twice the number of spheres in their place. The sim is no faster. I've also tried running the sim with while showing a hidden layer that has only a view joints rather than the usual 8 upper layers with all the fancy visual content in them. I still ca...

Re: Making wheeled vehicles with kinematics and no dynamics?

I've tried doing all explicit handling, it speeds things up a bit (a sim that took 2min 17sec on my PC now runs in 1min 57sec, the sim covers 7.4 sec of simulated time). How would I go about finding out whether there are any threaded scripts present which are wasting time and need to be stopped by s...
