Hi All,

I am simulating an autonomous robot. (Using ROS indigo, gazebo7, ubuntu 14.04) which should navigate in an unknown environment autonomously. I just want to use hokuyo laser and a small mobile robot. I am using gazebo7 but no robot are installing on gazebo7. It gives error while running catkin_make. I have made diffrential drive robot and I have added Hokuyo laser on it. How to make it navigate in the environment ? Is there any pre installed autonomous navigation for unknown map ? I just want to make robot to move autonomous and avoid the obstacle.

Hi,

I am very new to ROS. using ros indigo and gazebo7 on ubuntu 14.04

I've made diffrential drive robot using gazebo tutorial, if I want to move I have to use this command : rostopic pub /cmd_vel geometry_msgs/Twist "linear : x:0.1 y:0.0 z:0.0 angular : x:0.0 y:0.0 z:0.0" or keyboard teleop.

how to make robot start moving when simulation starts? without using keyboard teleop and the publish command.

I want to use hokuyo laser range finder. but i don't know how to get the data directly from hokuyo and robot should avoid the obstacle and move in other direction. In which files should I have to make changes?

Hi koko1234, I am doing Multi-robot exploration on ros (indigo)-gazebo7. I am very new to this. It will be good if we get in touch. It will be very greatful. Thank you
