The error you guys mention is a bug in VirtualBox: https://forums.virtualbox.org/viewtopic.php?f=3&t=42773 https://www.virtualbox.org/ticket/9198 In ARGoS, I use a QPainter to allow for overlay graphics to be added to the OpenGL widget. Qt internally implements this as a GL shader, and it seems ...

Hi,

I fixed that bug in the version of May 21st. It's not really a bug, just a warning that becomes an error when ARGoS is run in debug mode. Anyway, now it's fixed.

The colors are indeed weird. Maybe something is wrong with the driver?

Hi Mark, thanks a lot for all the effort :-) Just a remark: the command "argos" should not usually be run directly. Instead, I made the wrapper script "launch_argos". I know the trick of adding a file to the /etc/ld.so.conf.d directory. I preferred to avoid it and use a wrapper s...

The SetAperture() method is pure virtual in the control interface, true. But it is implemented for the simulated robot in argos2/simulator/actuators/foot-bot/footbot_gripper_actuator.h/.cpp. A factory creates the latter class, which is an extension of that in the control interface. In the controller...

I have fixed the dependencies in the new ARGoS release. Now the package I provided should work also on Ubuntu 12.04. Can you please confirm it? Thanks a lot!

Hi mallright, I am writing an extensive manual about ARGoS that contains all the information you need to create new robots. You got many things right :-) In a nutshell, any simulated object in ARGoS is an entity. Several entity types exist in ARGoS. Robots are typically derived from the Composable e...

I routinely use several Virtual Box installations to make and test ARGoS packages, and I have never encountered this problem. Anyway, the fact that some screen savers fail is pretty interesting, as it should not happen. What is the output of the command 'glxinfo', and of the command 'glxgears' ? If ...

This is a new problem to me.

Could you please be a little more precise on your system configuration? In particular, I'd need:

- Graphics card model
- Your Linux distribution and version
- Version of Qt installed

Thanks!

You're right. I should copy-paste more often Thanks for spotting it!
