Hello everyone.

---- Track2 question ----
This question is about task 3 and 4 of Track 2

In technical annex (page 33) you can find:

"Contestants can install and use any 3rd party software they need" with limitations on internet access, without using physical dongles, without using guest extensions on simclient VM.

in fact the only user available on the client VM is "simguest", and you can not have super user permissions.

The question is:
Can I sudo apt-get install some ROS package or I am forced to download source code and recompile the package under the simguest home ?
In the second case it doesn't seems to be really straightforward.

---- Track1 question ----
This question is about task 1 and 2 of Track 1

Is it possible to use physical dongles for Track1 (it was explicitly forbidden for Track2, what about Track 1) ?

Thanks in advance

It is not possible to have administrator rights on the client machine. You will have to sent it to us with your solution implemented on it. Then to prevent any cheating we cannot grant this machine with administrator rights.
3rdParty softwares have to be installed in your accessible directories (ie /home/simguest)

Thanks for the answer.

But I have to say that this will add difficulties.
For Example if I want to use MoveIt package:

- I cannot install it using the sudo apt-get install
- I cannot build it: also the compiling procedure requires super user permissions (the effort to resolve every dependence without these procedure steps can be so high you can be demotivated to use it)
- I noticed that on server VM there are some folders related to MoveIt (/home/simserv/devel/catkin_ws). Are they supposed to be useful for challenge teams ?
- I noticed that on client VM is missing every MoveIt package element.

Are we supposed to avoid the use of these so noticeable packages for these tasks ?

thanks in advance

For track 1 the usage of hardware dongles is forbidden as well.

Sorry for not explicitly stating this in the documentation. It will be added in the next revision.

The issue regarding administrator rights/installation of 3rd Parties is discussed internally and we will come back to you with a solution soon.

[bcoudrin]

We decided to add simguest in the sudo group on simclient to allow administrator rights.
A new simclient release will be available for download tomorrow morning.

Thanks a lot.
