FRCSIM Help

It works! we don't have the slow execution problem anymore. Although when we crash into the box the robot falls under the floor. It's a very minor bug though.

We'll tell you if the fix works. Thank you.

I'm running on a 2006 Dell XPS 400 with an Intel processor (PENTIUM D PRESLER, 940, 3.2G, 2X2M, C1) with 4GB of memory and a straight install of ubuntu 14.04 on the hard disk drive - no dual boot, no Windows on the system at all. I don't know what brand graphics card is in it (I tried to find a brand name on it, but didn't see one). I'm willing to try buying another graphics card if you can suggest one that would likely work and not cost more than $30-$40.

Dang, that's some ancient hardware. I'm not surprised it's not running on such old hardware. There's a lot more too it than "I have 4gb of ram!". Unfortunately, I'm the opposite of an expert on what hardware will support the 3D rendering Gazebo requires.

My first start would be to try some other 3d graphics tests--this likely isn't Gazebo's fault. Try installing and running "glxgears", or other Ubuntu 3D graphics tests. Also, you really do need to figure out if you have a graphics card... most laptops just have built in graphics. That isn't necessarily a problem (I use built-in graphics) but you should at least know

Ya, just watch out for setting motor speeds to Nan in usePIDOutput and the robot won't

fall under the floor.
