The simulator is composed of the following parts (all credits to their authors):
Rosjava_core - java-based implementation of ROS core
-and potentially with some necessary ROS-components (e.g. messages) included
Together, these packages provide mostly platform-independent tool for simulating hybrid neural systems usable e.g. for experiments with e.g.:

Javadoc for sub-projects which are not available here can be generated from the particular project folder by the following command:
Te resulting documentation will be placed under
pip install -U wstool
brew install gfortran
download virtualenv and wrapper
sudo pip install virtualenv sudo pip install virtualenvwrapper
create ~/.virtualenvs directory
create your virtualenv
mkvirtualenv nengoros source ~/.virtualenvs/nengoros/bin/activate
pip install numpy pip install scipy
Make folder with workspace:
mkdir -p ~/workspace && cd ~/workspace
In case of ROS not installed, point the ROS_PACKAGE_PATH into this folder (add to your ~/.profie or ~/.bashrc file )
Download Nengoros configuration:
git clone -b nengoros-master-v0.0.5 https://github.com/jvitku/nengoros.git
Download all repositories and install them (./tool -h)
cd nengoros ./tool -unrf
In Eclipse, import all auto-generated projects from nengoros folder (it is necessary to check the check-box
search for nested projects, and after importing delete the projectTemplate), clean & build them in Eclipse.
Now the simulator can be launched from class files generated by Eclipse. In order to launch GUI, start the script under nengo/simulator-ui:
In order to launch command-line interface, start the:
Demos for the Nengoros can be found on the official project sitehttp://nengoros.wordpress.com.
Additionaly, there are two choices how to learn with NengoROS:
demonodes, where all demos are placed, see its readme for all information.
nengo/simulator has the src folder set to:
src/java/test/ctu to ensure that all Nengo tests are omitted, in order to run also Nengo tests, set this folder to
The tool script is used to update the multi-project from repositories. Now, the complete.rosinstall version is suported. Various older versions are placed under
.versions folder. In case you want to choose which version to use, e.g. for rosbased (creates .rosinstal file):
wstool init -j8 . .versions/rosbased.rosinstall
Run the tool script:
THe script tool can update all projects from remote repositories:
Describes development of the project, the TODO chapter can be found in the
Completely rewritten NeuralModule and DefaultNeuralModule.
Added support for multiple Terminations for Encoder. Each Encoder now has MultiTermination. Now, the following can be used to add the weighted Termination
Added three possibilities how to sync time between Nengo and ROS nodes: TimeMaster, TimeIgnore and TimeSlave. These are used in the
Added demos representing time synchronization in the project demonodes/basic, the corresponding python scripts are located under
The first stable version. Version is mainly taken from my older repositories on bitbucket.org.
Includes demos on rosjava, ROS nodes and native process.
Communication with ROS nodes is synchronous or asynchronous
