GLV's profile - activity

Hey There, I am new to ROS and Gazebo. I want to know what is the self collide what is the use of it (when it true or false) and also the difference between visual and collision? ( I am facing these words while using Link inspector)

Thanks Mr. #duck-development.

When I tried to execute this, I got following error:

glv@VaraPrasad:~/catkin_ws$ rosrun rosserial_
rosserial_arduino  rosserial_client   rosserial_msgs     rosserial_python
glv@VaraPrasad:~/catkin_ws$ rosrun rosserial_python 
message_info_service.py  serial_node.py           
glv@VaraPrasad:~/catkin_ws$ rosrun rosserial_python serial_node.py /dev/ttyACM1
[rosrun] Couldn't find executable named serial_node.py below /opt/ros/kinetic/share/rosserial_python

In this Tutorial I encountered this rosrun statement, why we need to run this glv@VaraPrasad:~/catkin_ws$ rosrun rosserial_python serial_node.py /dev/ttyACM1 what is the use of it. And how to overcome this error??

Thanks In Advance

How to Visualize the turtlebot path? Hi there, I implemented a Spanning tree coverage algorithm for Turtlebot. Finally,

will I get odometry/filtered values like robot_localization by doing SLAM?

How to publish a map frame? I'm working on ardrone2.0. I'm trying to fuse odometry and imu through robot_localisation.

When I am trying to launch the my_world.launch I am facing this problem.

Code for my_world.launch is

<?xml version="1.0" encoding="UTF-8"?>

<launch>
 <arg name="debug" default="false" />
 <arg name="gui" default="false" />
 <arg name="pause" default="true" />
 <arg name="world" default="$(find my_gazebo)/world/empty_world.world" />
 <include file = "$(find gazebo_ros)/launch/empty_world.launch">
  <arg name="world_name" value="$(arg world)" />
  <arg name="debug" value="$(arg debug)" />
  <arg name="gui" value="$(arg gui)" />
  <arg name="paused" value="$(arg pause)" />
  <arg name="use_sim_time" value="true" />

 </include>

</launch>

empty_world.world code is here:

 <?xml version="1.0" ?>
    <sdf version="1.6">
      <world name="default">
       <include>
         <uri>model://sun</uri>
       </include>
       <include>
         <uri>model://ground_plane</uri>
       </include>
      </world>
    </sdf>

I am facing this problem:

@Mr.AbhijithNair could you please tell me how you convert Kinect data to point cloud. which packages did you use? could

In order to get a position I have to launch this code https://github.com/ros/common_msgs/bl.. or I need to clone all pa

Hi Everyone,

I am working on turtlebot and kinect sensor. I want to detect obstacle presence and its position using kinect sensor. How could I do this and I am not using maps. Just want to know whether obstacle is there or not. And if I am going to use point cloud libraries, how can i get obstacle position(X,Y) .

(I am using Ros kinetic version,Ubuntu 16.04 and python as coding language.)

Thank you so much #Mr.tfoote

How to use openni_camera for turtlebot_gazebo world? Hi there, openni_launch and openni_camera can't detect my simulate

Thanks for your answer #Mr.tfoote. This tutorials in C++ can i get in python anywhere? Could you pls give me some sugges
