Hi

I have a patrolbot which the navigation under ROS is implemented. And well, it seems to be as if the navigation is working properly. Just one issue 1.-when I set the '2d pose estimate' under rviz and then '2d nav goal' the robot goes from the actual pose to the goal with a lot of rotations.

The question is if there is any way to make the robot goes a straight line, e.g. I will probably need to tune some parameters. Do you know which ones,

Any help will be great

Dear all.

I have a new topic name for a LaserScan.

When I run:

rosrun gmapping slam_gmapping scan:=new_topic_name

The gmapping takes the data under the new topic name.

However when I run a launch file

node name="slam_gmapping" pkg="gmapping" type="slam_gmapping" args="new_topic_name"

respawn="false" output="screen">

The gmapping doesnt take the data under the new topic name, it takes instead the data from the scan topic.

Can somebody explain why and how to solve that issue.

In advance thank you to all.

Dear all.

I have navigation stack implemented and I can send some goals to the move base.

I just want to cancel a goal before it reaches its position using feedback.

How can I use feedback?

I have use the following code, but it doesnt work.

ac.sendGoal(goal, &feedbackCb);

void Pose_Goal::feedbackCb(const move_baseFeedbackConstPtr& feedback){

ROS_INFO("[X]:%f [Y]:%f",feedback->base_position.pose.position.x, feedback->base_position.pose.position.y);

}

any help I would appreciate it. Thanks in advance
