I've been asked a couple of times how to use Blender for robotics lately. I truly believe that Blender offers a serious alternative to existing frameworks and simulation engines, and therefore, I decided to write an extensive tutorial that explains most of the work I did with Blender. Before I'll go into details, I'd like to point out (recommend) a few things. Some of the conclusions drawn here might be obvious and trivial. Anyway, I decided to write this down to give beginners a chance to start using Blender for robotic purposes and to avoid time consuming pitfalls — I used to stumble upon. The knowledge presented here is mostly based on my personal experience and might (sometimes) not reflect best practice, despite that, most of it worked for me. If you have any comments, proposals, and improvements: please comment or drop me a line. Constructive review is highly welcome.
A while ago, I was confronted with using CTest output in our Jenkins CI server. Well, I found one or two solutions on google (Stackoverflow , precisely), but there are a few pitfalls, that's why I decided to write the whole thing down [for you].
In case your X Server won't start on Ubuntu 12.10, and xorg.0.log indicates this error:
(EE) NVIDIA(GPU-0): Failed to tear down EVO channel
(EE) NVIDIA(GPU-0): EVO Push buffer channel allocation failed
(EE) *** Aborting ***
(EE) NVIDIA(GPU-0): Failed to allocate EVO DMA push buffer
(EE) *** Aborting ***
Try adding Option "UseDPLib" "off" to your Device section in the xorg.conf
Adding additional SSL Certificate to default ca bundle | SSL Certificate Chain Verification | ca-bundle.crt
Sometimes you need to connect via SSL to a website or service and you will most probably get stuck
because of openssl/ssl issues. With curl for instance:
No cURL data returned for https://my.webserver.com:443  SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
Disabling the SSL verification checks is not a good idea, because possible of MITM attacks.
It only takes two minutes to install the AR.Drone 2.0 SDK and try some first moves in the air. So far I am ... well, amused. Let's see what the actual hacking brings...
