Hi, I'm really new to ROS, just finished the beginner level of ROS tutorials (just had some rough ideas about topics, publishers, subscribers, etc.). My project is having this Kuka manipulator interact with human according to images captured by a Kinect sensor. So, my question is what should I look for my next stage? Learn ROS-Industrial? Gazebo simulation (I do want to do a simulation of my application but I have no idea how to do it with ROS)?

I guess the original ORB-SLAM2 does not publish map topic. You'll need to use other libraries such as PCL and octomap to

I think the developers answered my question. It was just the log type issue not a real error. I did not install the addi

Yes, you are right. I figured out this a couple of days before but forgot to check this answer back. Thank you.

Hi guys, As I'm trying to follow this tutorial from OpenAI_ROS to play around Q learning on a Gazebo simulated turtlebot in a maze. However, I cannot initiate my turtlebot. I have succesfully downloaded and built openai_ros and openai_example_projects in my ROS workspace. I'm using Ubuntu 16.04+ROS-Kinetic + Gazebo-7.0.

Basically, I'm following these steps:
1. $ roslaunch gym_construct main.launch to start gazebo simulation (this part looks fine to me).
2. $ roslaunch turtle2_openai_ros_example start_training.launch and this will give me following error messages.

Don't worry @NEngelhard, I really just want to start a simulation first. And my project is not about interact with the r

Thanks, @gvdhoorn. I think starting from a simulation would be great, and I'm willing to learn all kinds of ROS stuffs.

Can I manipulate a Kuka kr10 with ROS? Hi, I'm really new to ROS, just finished the beginner level of ROS tutorials (jus
