2016-12-07 15:12:27 -0500 asked a question Joystick operation for a gazebo ros youbot

Hi everyone,

I have created a node just like teleop_joy using ros.org. It publishes a topic /joy and the type of message is sensor_msgs/Joy. My youbot has a topic /cmd_vel and the type of message is geometry_msgs/Twist. I want to move the youbot using joystick by subscribing /cmd_vel to /joy but the type of messages are different. How can I do this? Any ideas please

2016-11-28 08:19:21 -0500 asked a question Subcribing to the Odometry

Hi, I have a gazebo model which is moved by teleop_keyboard. My model has a node which publishes Odometry values in X and Y and it has nav msgs.. I want to subscribe the turtlesim(topic turtle1/pose) to my model node and make it move in the same coordinates. How can I do this?

2016-11-07 08:58:17 -0500 commented question Hi, I Have the odometry readings from a robot, How can I make the other robot to subscribe to this readings and make it to be in same coordinates and same movement??

First robot is commanded by a joystick. And yes I want to match the movements including coordinates. Help me

2016-11-02 17:10:00 -0500 commented answer Hi, How can I path plan a robot in ROS+gazebo using indoor GPS and odometry data?

I am using infrared beacons to get the coordinates of the robot. It has got a ROS package and able to show the x,y,z coordinates
