Re: Crash when starting and stopping simulation with remote

I'm pretty sure it is related to how the Python code affects the scene. One thing I noticed is that I was starting up the remote API from within the scene's initialization to a particular port, and I don't think it was being explicitly closed anywhere (I needed this in the past because I had two sep...

Re: Crash when starting and stopping simulation with remote

I ran it with debug information on, it took about 2 days to finish and didn't crash. It might be that this error doesn't come up when it is being run slowly.

Re: Crash when starting and stopping simulation with remote

I'm running Ubuntu 14.04 and V-REP version 3.2.1 I haven't seen it crash on an empty scene yet. It seems very unpredictable. Sometimes it will run for hours and be fine, and other times it will crash after 30 minutes, and other times it will crash after 5 minutes. The error isn't always in the same ...

Crash when starting and stopping simulation with remote API

I'm using the Python remote API to run a series of simulations. Each one is about 10 to 20 seconds long and I am stopping and starting the simulation after each run (to reset it to its original state). I am seeing V-REP crash often during these runs (typically 15 - 20 runs in). The error that shows ...

Re: Using a proximity sensor nested inside another object

Turns out the base of the sensor was overlapping with the robot body slightly. I moved it 0.01 units out and now it works fine. I'm guessing it was just seeing the robot in its "too close to detect" zone and so it was returning 0 all the time.

Using a proximity sensor nested inside another object

I would like to attach a proximity sensor to a robot, but it doesn't seem to be able to detect anything if it is not at the base of the scene hierarchy. How would I be able to get the sensor to move with the robot, yet still be able to detect obstacles? My code looks like this: --inside initializati...

Re: Select Groups of Objects in the Scene Hierarchy

Nevermind, figured it out. Shift+Click and drag does the trick

Select Groups of Objects in the Scene Hierarchy

Hello, Is it possible to select multiple objects in the scene hierarchy without selecting them all individually? The normal way this is done is with Shift+Click, but in V-REP Shift-Click works the same as Ctrl-Click (only adds one new object to your selection, rather than selecting all between). I h...

Re: Scatter Plot

Is there any way to change the physical size of the points? I want to make them smaller so they don't all blend together. I took a look at the 3D laser scanner example, and I think I understand how the X/Y/Z scatter is being drawn on the scene (creating a series of points and displaying them), but I...

Scatter Plot

Is it possible to create a scatter plot in V-REP? If not, do you know of a way to get the XY graphs to look close to one? I can get it to display a series of dots instead of lines, but I don't know how to make those dots smaller or allow more than one at each X position. Thanks!
