This is modification of original Nengo simulator for integration with ROS infrastructure. For more information about Nengo-ros integration see: http://nengoros.wordpress.com/ .
Author: Jaroslav Vitku [[email protected]] Address of this repository: https://github.com/jvitku/nengo_1.4/
This modification is used in the "nengo-ros" package, which integrates (all credits to authors) :
-
Nengo simulator - large scale neural simulations (original readme renamed to
README_origNengo.rst
) -
Rosjava_core - java-based implementation of ROS core
-and potentially with some necessary ROS-components (e.g. messages) included
Together, these two packages provide platform-independent tool for simulating hybrid neural systems usable e.g. for robotic applications.
If you want to install the entire Nengo-ros multiproject (recommended), see http://nengoros.wordpress.com/ or clone the repository on https://github.com/jvitku/nengoros
If you want to install just the modified Nengoros simulator (with precompiled rosjava libraries), see the next chapter.
To obtain the recommended complete installation, see installation instructions.
In order to install just standalone version of Nengoros, you can use the script ./installStandalone
.
-
This generates eclipse projects into the folders simulator and simulator-ui.
-
In Eclipse, import (simulator and simulator-ui) projects from nengo folder, run:
clean & build
in Eclipse. -
Launch Nengo by calling main method in class:
NengoLauncher
or by running scripts eithersimulator-ui/nengo
orsimulator-ui/nengo-cl
.
###nengoros-master-v0.0.4
- Added support for the my modification of the Vivae simulator. More precisely: the old version of Vivae support was removed from the Nengoros and placed into the
vivae/vivaeplugin
project.
###nengoros-master-v0.0.2
-
Added three possibilities how to sync time between Nengo and ROS nodes: TimeMaster, TimeIgnore and TimeSlave. These are used in the
ca.nengo.util.impl.NodeThreadPool.step()
. -
Added demos representing time synchronization in the project demonodes/basic, the corresponding python scripts are located under
nr-demo/basic/time*
###nengoros-master-v0.0.1
-
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
###Gradle tests
The project 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 src/java/test
.
###Other
-
Note that the standalone version contains only pre-compiled rosjava_core jar files and no additional projects, so the limitations are:
- Does not include any demos (or those included may not work correctly).
- User cannot define custom messages (interfaces for messages are generated during rosjava_core compilation)
-
Compared to Nengo, the build system is changed from Maven to Gradle (which is used by rosjava_core).
-
In order to distinguish between standalone and rosjava-based project settings, build.gradle and settings.gradle files under nengo and nengo/simulator-ui are appended with either *.rosjava or *.standalone, please, edit these files.
