The tools you need to interact with Vizzy robot.
The simulated robot is currently checking collisions with the high-polygon count meshes instead of using a simpler blocky model.
This may be why the performance is so low with gazebo.
Essentially means the urdf must be revised.
The offset parameter of the DH parameters of the elbow joint need to be updated (5deg). The corresponding transform needs to be updated.

The camera frame_id published on the camera_info topic is incorrect. The correct one should be "_camera_vision_link" instead of "_camera_link".
right and left wheel joints have to be switch for the plugin to work properly. Need to find the cause
Hi @plinioMoreno (+ @ruipimentelfigueiredo @joao-avelino),
Last summer, we started copying the documentation of Vizzy on the wiki associated to this repository, here:
https://github.com/vislab-tecnico-lisboa/vizzy/wiki
Personally, I think it would be good to put the remaining documentation (i.e., the PDF manual) on the wiki too, in order to (1) have it all in one place, (2) make it easily and quickly updatable in the browser, (3) facilitate the transition of knowledge if some of you ever leave the lab (I hope not! but just in case :) ).
Furthermore, it will still be possible to generate printable PDFs (from GitHub wiki Markdown syntax) by using tools like this one: https://www.npmjs.com/package/markdown-pdf

Hi!
When trying to install the eband-local-planner, i get the error:
Unable to locate package ros-hydro-eband-local-planner.
Where else i can find that package, i tried to search but with no success.
Thanks
Following the changes made in the gazebo-performance
branch, since the urdf has been changed, the MoveIt! package needs to be regenerated before it can work once again.
Preferably we could have two versions: one which uses a simplified model of the hand and another with a more detailed mesh for collision (maybe even capable of grasping experiments).
As of right now, the detailed hand is not yet implemented, but the arm description file has an empty slot where it should be instanced.

Hi @plinioMoreno @ruipimentelfigueiredo @joao-avelino!
I noticed that the whole vizzy repository takes about 200MB at the moment, the majority of which due to the larges files in vizzy_navigation/maps (115MB).
Suggestion: host those large files elsewhere using Git Large File Storage, which looks like a nice possibility for these cases. Cloning/Working with the vizzy repository will be faster, while those files will still be available and maintainable on the "external" LFS reference.
After downloading the content of the whole Vizzy repository, when I tried to run, I got the following error
$ roslaunch vizzy_launch vizzy_simulation.launch use_yarp:=true navigation:=true
< a lot of stuff and then the error >
roslaunch.substitution_args.ArgException: use_yarp

It seems that the file vizzy-master/vizzy_moveit_config/launch/planning_context.launch is incomplete.
The Gaze changes abruptly during some demos when the points are sent in a continuous way.

These controllers should act like the yarp ones. So my question is: How are you going to implement the version-vergence controller?

Look to everything new and try to create a better and more useful documentation.
The current navigation algorithm in simulation is the "fake_localization", which for initial debugging was very useful, but for testing code for the real robot does not consider the execution times of the amcl in the real robot.
The amcl should be available in simulation, in order to have a more realistic simulation of the navigation algorithm.

Add documentation regarding Vizzy's hardware
We should use Miguel Aragão's master thesis work to send vizzy's current fixation point (provided by the Ikin gaze controller) and the ball position (provided by Matteo's ball tracker) to ROS side, for visualization purposes.
If the clocks on Vizzy and a networked device (laptop for instance) are not synchronized tf's throw an exception.
The solution is here: http://wiki.ros.org/ROS/NetworkSetup#Timing_issues.2C_TF_complaining_about_extrapolation_into_the_future.3F
