I found a solution by using a hidden input and got the URL:

You have to install ROS2 before building Move It 2. After installing the ROS2 binaries, the error doesn't occur.

Since I do not have complete context of the dictionary and other details, I would suggest using df.apply(operation) , it often causes speed ups rather than iterating.

pandas.DataFrame.apply

But I don't know why launching the robot on the rviz platform does not publish the camera topic.

That's easy: Because Rviz is a visualization tool and wasn't originally made for simulating a virtual environment. In other words: It can show you what the robot sees but it doesn't pretend to be the robot. Publishing a camera topic would basically mean that the visualized robot in Rviz pretends to see something itself: the Rviz-world.

cause I am facing some error spawning the robot in gazebo platfrom.

Other than Rviz, Gazebo is a very good choice for simulating a robot as well as designing an environment that a simulated robot-camera can see and publish. If you have trouble spawning the robot, you should probably look for a way to solve that rather than trying to use Rviz as simulation-tool.

But there does seem to be a way to use Rviz for simulation, as stated here:

rviz_camera_stream publishes an image rendered in rviz. It builds in jade at least, but likely works in hydro and indigo, and following the fork back leads to a pre-catkin version.

It needs an input camera_info to get camera intrinsics and resolution. The distortion coefficients are ignored, but a image_proc like node that implements http://code.opencv.org/issues/1387 could address that downstream. (Do gazebo cameras support distortion yet? http://gazebosim.org/tutorials?tut=ca... says version 5.0 does)

The input camera_info topic and output image topic are set in the rviz plugin gui.

Old suggestion:

One hacky solution is to run a screen grab node http://wiki.ros.org/screengrab_ros and position the rviz window just so, though it would be very brittle and hard to automate with launch files.

Because you want to add the gripper and robot together on the MoveIt, I think the easiest way is using MoveIt Setup Assistant to do it.

http://docs.ros.org/en/melodic/api/moveit_tutorials/html/doc/setup_assistant/setup_assistant_tutorial.html

Inside Techman Robot ROS, it provided robot model(tm5-700, tm5-900 and tm12 1300 type), so you can get the robot model. The only thing is you need to do is add your camera model and gripper model.

By the way, MoveIt is a planning the robot trajectory, it doesn't matter about the other sensors.

This will be useful.Please try out this.

It is because you declare window.onscroll twice and therefor it overwrites the first declaration. You just have to add the call of growShrinkLogo() to the second window.onscroll.

Working example:

A single audio cannot be playing in multiple instances. The audio must finish before it can be played again.

You must replace this code:

please don't give me any advice on how to "fix it". I know how to fix it. This isn't my question.

OK.

This is purely a curiosity based question. I just want to understand why does the speed increase. What makes it increase.

So we see that when moveIt is called it will always reschedule itself to be run again, using setTimeout. This means that once you call it, you have started an infinite sequence of calls, each separated by 25ms.

When the Start button is clicked, moveIt gets called. So far so good. It's doing what it should do. The Stop button works fine too. moveIt keeps continuing its repeated calls, but the stop variable now prevents it from making any changes.

The user clicks the Start button again. Now things go wrong: moveIt gets called again. So now we have two self-propagating sequences of moveIt calls. You can see how that doubles the speed of the changes.

In short, make sure you only call moveIt once, and let setTimeout do the rest. Don't call moveIt explicitly again.

You write in comments:

I thought about that, but when I tested that scenario, I ended up dismissing it.

Then I think you did not test it correctly. So now I will provide the fix:

In the function secondstart remove the call to moveIt:
