[ROS#资讯汇总（ROS、C#、.NET和Unity3D）]

ROS＃是C＃中的一组软件库和工具，用于.NET应用程序（尤其是Unity）与ROS进行通信。

之前博文涉及windows系统与ROS应用可参考（ROS2有windows版本）：链接1、链接2。

^_^

本文是西门子公司的Martin Bischoff客座博客文章。 感谢Martin的更新，感谢西门子对ROS-Industrial Consortium的支持！

ROS#包括如下内容：

• RosBridgeClient, a .NET API to ROS using rosbridge_suite on the ROS side.
• UrdfImporter, a URDF file parser for .NET applications.
• RosSharp.unitypackage, a Unity Asset package providing Unity-specific extensions to RosBridgeClient and UrdfImporter.

ROS#可以实现功能有：

1. Communicate：通过Windows应用程序与ROS进行通讯：订阅和发布主题，调用和发布服务，设置和获取参数以及使用rosbridge套件提供的所有功能。

2. Import：将机器人的URDF模型作为GameObject导入到Unity3D中。 使用robot_description服务直接从ROS系统导入数据，或通过复制到Unity资源文件夹中的URDF文件导入数据。

3. Control：通过Unity3D控制真实机器人。

4. Visualize：在Unity3D中可视化机器人的实际状态和传感器数据。

5. Simulate：使用URDF提供的数据在Unity3D中实现机器人仿真（这里不使用与ROS的连接的方式）。 除了网格和纹理的可视化组件之外，还可以导入了刚体的关节参数、质量、CoMs、惯性和碰撞等规格指标。

6. And much more：更多功能！ROS＃可用于各种应用，如机器学习、人机交互、远程监控、虚拟原型、机器人操作、游戏和娱乐等！

ROS# is a set of open source software libraries and tools in C# for communicating with ROS from .NET applications, in particularUnity3D.

Find some examples what you can do with ROS# here.

Contents:

RosBridgeClient

... provides a .NET API to ROS via rosbridge_suite.

UrdfImporter

... provides a URDF file parser for .NET applications.

ROS

... contains code for ROS nodes and ROS launch files which are useful to RosBridgeClient and/or UrdfImporter.

Unity3D

... is a Unity3D reference project providing Unity3D-specifc extensions to

• RosBridgeClient
• UrdfImporter

Release

... contains RosSharp.unitypackage the latest package of ROS# assets from the Unity3D project.

Tutorials

... contains Unity3D tutorial projects described described in the Wiki.

Licensing:

ROS# is open source under the Apache 2.0 license and is free for commercial use.

External Dependencies:

RosBridgeClient uses the following 3rd party libraries:

• websocket-sharp.dll from websocket-sharp provided under MIT License.
• NewtonSoft.Json.dll from NewtonSoft Json.Net provided under MIT License.

UrdfImporter uses the following 3rd party libraries:

• MathNet.Numerics.dll from Math.NET Numerics provided under MIT License.
• System.Threading.dll from TaskParallelLibrary for .NET 3.5 provided under MS-EULA License.

.NET Standard 2.0:

Both RosBridgeClient and UrdfImporter are running on .NET Framework 3.5 as this is the .NET platform currently supported by official Unity3D releases.

For Non-Unity3D-Applications blommers kindly provides a .NET Standard 2.0 version of UrdfImporter.

Special Thanks:

• Rahul Warrier for adjusting the code to enable its open source publication.

• Verena Roehrl for providing the Wiki pages and the tutorial projects.

• Karl Henkel for providing the reference for the Unity3D STL mesh importer used in this project.

• Jeremy Fix for providing the CameraImagePublisher and VelocitySubscriber

• Interested in contributing as well?
