我今天嘗試的用Mac OS 10.15 安裝 ROS2.0 Eloquent

根據這個網站安裝 https://index.ros.org/…/Ins…/Eloquent/OSX-Development-Setup/

可是在執行. ~/ros2_eloquent/install/setup.bash 設置環境時，卻出現

not found: "/Users/XXX/ros2_eloquent/local_setup.bash"

請問有人有遇過相同問題嗎？

各位先進好，想請教大家一個問題。

關於為何ROS1無法部屬在RTOS的系統上?

根據論文"(2016)Exploring the performance of ROS2"中提到，ROS1傳輸訊息的方式是透過TCPROS/UDOROS，ROS 2則是使用DDS。

我可以理解為是因為兩者的訊息傳遞的通訊架構不同才導致的嗎？既使今天Linux裡有逐步實現posix相容，但TCPROS沒有使用到，所以沒辦法達成real-time嗎?

一直在想要如何用更白化的方式解釋，但有點卡，感謝大家:)

猶記得今年舉辦的ROS 2.0 技術論壇中，有聽到Microsoft在發表的最後面短短的說了一句，未來微軟會讓vscode更加支援ROS

然後從今年尾開始，在vscode中的ROS plugin功能性開始大增!

截至目前為止，新增了幾項方便的功能: 可視化URDF: 你可以直接在vscode中即時的看你的urdf檔案呈現的3d外型如何
直接針對單個節點(rosrun)設中斷點debug 對roslaunch啟動的節點設中斷點debug
尤其是後面2點，改進了ros很難debug的問題XD
(以前只能用GDB之類的東西，學習難度不低....)

感恩微軟~讚嘆微軟~

Ros2 安裝在Mac OS Mojave有些問題想請教

我依照https://index.ros.org//doc/ros2/Installation/Crystal/OSX-Install-Binary/

安裝，但執行ros2 run demo_nodes_cpp talker時他會發出警告

dyld: Library not loaded: /usr/local/opt/poco/lib/libPocoFoundation.60.dylib

Referenced from: /Users/chenwei/ros2-osx/lib/librosidl_typesupport_c.dylib

Reason: image not found

然後我到路徑裡面尋找，發現只有libPocoFoundation.62.dylib，沒有libPocoFoundation.60.dylib

所以我猜需要將poco的版本降下來，可是我發現我不會用brew 降版本，有哪位大大知道嗎？

各位您好，想詢問關於執行uvc_cam時出現Setting exposure is not supported Setting gain is not supported，該如何排除呢？

本週直播 #62: Visualizing a Robot URDF in RViz (LIVE on July 2) http://www.theconstructsim.com/ros-developers-live-class-d…/

Visualizing the status of the URDF you are building is a big help when trying to build complex robots.

In this class, you will learn how to use RViz to visualize your URDF at each step of the development of the model, so you can detect errors quickly and correct them.

ROS開發者大會2019 http://rosdevcon.com
介紹:
The ROSDevCon 2019 is a hands-on online conference for ROS developers. The conference aims to connect ROS developers around the world without geographical restrictions and to advance ROS levels through real-time practice.

During the conference, all participants will practice in real-time on any type of computer while the speakers are presenting. With a ready-made ROSject, participants will be able to launch the robot simulation, access the project's code, start developing control algorithms...without any previous setup. All the participants will have

- Access to the conference LIVE streaming
- Full access to the ROS Development Studio (ROSDS) for programming
- Full access to the online chat tool with all participants and ROS experts
- Access to ROSjects (containing simulations, packages with pre-defined code)
- An e-book of ROS2 Basics
- Access to the video recording
