ROS.Taiwan 造訪社團 » CAM

各位好，最近在使用ducketown 學習ROS ，遇到一個問題，希望有機會能在這裡得到解法。

我的問題是: 輸入 rostopic list 可以看到 "/duckpi/camera_node/image/compressed" 這個topic ，但是進入rviz [add]-->[by topic] 時卻看不到 "/duckpi/camera_node/image/compressed" 請問有可能是哪裡做錯了嗎?

RViz version 1.12.17

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？

[Resources about ROS-Industrial]

—> Video | How to Launch a ROS Industrial Robots Simulation
http://www.theconstructsim.com/ros-qa-117-how-to-launch-a-…/
In this video we will see how to launch a complex industrial environment with several robots in it, including ROS industrial robots and service robots. The simulation contains a UR5 industrial robot and a couple of mobile bases. Also, many types of sensors include, including lasers cameras, and even a conveyor belt simulation.

—> Video Tutorial | ROS Industrial 101 + programming UR5
https://youtu.be/J6Mu1P6FlxY
ROS-Industrial is a project which main goal is to bring ROS closer to the robotics industrial world. It is a HUGE project, composed of many packages and tools.

This course will introduce you to some basic concepts you need to know if you want to begin exploring all the ROS-Industrial capabilities. You are going to work with a Moto man Sia10f simulation and an UR5 simulation

—> Article | ROS MoveIt!: All You Need to Know To Start
http://www.theconstructsim.com/ros-movelt/

—> Webinar | Using MoveIt! with ROS Industrial
https://youtu.be/cPJsNqZdm6E
In this webinar we will teach you how to use MoveIt! for controlling an industrial robot with ROS.

—> LIVE Class | How to use ROS with industrial robots
https://youtu.be/BCDFvMw6N-8
In this LIVE Class we are going to learn how to control industrial robots using ROS. For that, you are going to program with me a UR5 arm robot with MoveIt! in order to grasp pieces from one side and put them in another.

—> LIVE Class | Simulate an Industrial Environment
http://www.theconstructsim.com/ros-developers-live-class-2…/
In this Live Class we are going to execute ARIAC simulation made by the OSRF. We are going to learn how to manage that simulation in order to make the robots perform useful tasks in the environment. We will indicate where Gazebo plugins were applied, how SDF was used to create the environment, were ROS control was applied, where ROS navigation was applied, etc. We will see how to create a simple Python program that allows us to make the robots do useful things.

ROS-I 最新公布的ROS-compatible 3D sensors清單
https://rosindustrial.org/3d-camera-survey/

我自己有用過:
kinect v1 & v2
Astra & Astra Pro
Realsense R200/SR300/D435
ASUS Xtion/XtionPro
ZED
還有自幹的PS4 Eyes
自己做硬體同步的兩顆PS3 Eye
以及只有軟體同步的兩顆UVC camera

就我自己的使用心得
我偏好 XtionPro, Astra, D435
可惜前面兩個買不太到了
後面那個缺貨XD
