Ros waypoint navigation

I would like to know how to send mutliple goals to a robot that doesn't have LaseScan to create a map. Now, I am want to make my robot follow a path. I saw we could use waypoints but I am not really sure about how to do this.

As for the waypoint navigation, you can write your own node that can send multiple waypoints using SimpleActionClient from actionlib. In my case, the robot only has an ultrasound sensor. This can ask this as a separate question. You should check for existing layers like this one and this question might have some info.

Ask Your Question.But I don't know how to implement this. It is strange to me how something like GPS waypoint following is no clearly documented. I have been trying to make this work on Jackal for some time now and still am having problems.

I have gotten about to where you are. It is very strange to me, too! This is very strange since there is lots of documentation about all the other ROS topics, but almost nothing about GPS and waypoint.

I'm very sad about this since this topic is very important to me. Have you tried this? It does not say much, for that matter none of the answers say much. I already read it but it provides no additional information. But that's unrelated to GPS waypoint following. Fortunately, there are a couple libraries that do this. You can include that header file and call the function I've linked, and it will give you what you want. Cont'd: You don't need them, which is why the publication is optional. It's just handy if you have some other node that needs your GPS position.

Thank you a lot! I'm going to try to implement this. Continued: I'm asking this since I would like to make the robot consider the goal as reached only when the current GPS coordinates read by the robot will be equal to the given goal GPS coordinates. Will this affect the GPS? Please start posting anonymously - your entry will be published after you log in or create a new account.

The code receives waypoint information from user as well as the left and right sensor data. The code receives the relative position of the waypoint to the robot base. Skip to content.

It can navigate while building a map, avoiding obstacles, and can navigate continuously between each goal or stop at each goal. For additional information and instructions on how to use the package, see Clearpath Robotic's blog post and tutorial. Instead, email me at nicholas. Regarding the calibration node: the heading calibration node is not required if your magnetometer is calibrated correctly.

Instructions for performing magnetometer calibration are hard to come by, so often they are not calibrated correctly. This will only temporarily solve your problem and must be run every time you start this package.

We recommend instead to perform proper magnetometer calibration. The continuous waypoint navigation software was tested in simulation and works well in simulation, however it still doesn't work properly with our tests outdoor.

This code is meant as a tutorial to perform waypoint navigation using common ROS packages. It has not been tested for robustness and should not be used as a final product. If you are looking for a final working GPS waypoint navigation solution, please contact Clearpath Robotics, as they have recently developped a more commercial solution. Skip to content.

In this example, that task is to take a given set of waypoints and navigate to a set of positions in the order provided in the action request. The last waypoint in the waypoint array is the final position.

It is given an array of waypoints to visit, gives feedback about the current index of waypoint it is processing, and returns a list of waypoints it was unable to complete.

When false, it will continue onto the next waypoint when the current waypoint fails. No questions yet, you can ask one here. Failed to get question list, you can ticket an issue here. Package Summary. Tags No category tags. Version 0.

This will complete dynamic path planning, compute velocities for motors, avoid obstacles, and structure recovery behaviors. To learn more about this project see About and Contact. Navigation 2 uses behavior trees to call modular servers to complete an action. An action can be to compute a path, control effort, recovery, or any other navigation related action.

The diagram below will give you a good first-look at the structure of Navigation 2. Note: It is possible to have multiple plugins for controllers, planners, and recoveries in each of their servers with matching BT plugins. This can be used to create contextual navigation behaviors.

It will then provide valid velocity commands for the motors of a holonomic or non-holonomic robot to follow. We currently support holonomic and differential-drive base types but plan to support Ackermann car-like robots as well in the near future. We also provide a set of starting plugins to get you going. DWB will use the DWA algorithm to compute a control effort to follow a path, with several plugins of its own for trajectory critics.

There are recovery behaviors included: waiting, spinning, clearing costmaps, and backing up. There are a set of BT plugins for calling these servers and computing conditions.

Finally, there are a set of Rviz plugins for interacting with the stack and controlling the lifecycle. A list of all user-reported plugins can be found on Navigation Plugins. Here is the documentation on how to install and use Navigation 2 with an example robot, Turtlebot 3 TB3as well as how to customize it for other robots, tune the behavior for better performance, as well as customize the internals for advanced results.

Next, launch Rviz and check the TF tree, you should see something like this:. You should see utm in the list. The easiest way I've found to check the existence of the utm frame is to check it like this in Rviz. You should be able to specify whatever frame you want in the header. If you want a more complicated way of doing this that also lets you get feedback on your goal, I suggest you look at the actionlib package and these questions here and here for more information and some sample code.

Hopefully this helps or at least points you in the right direction. Let me know how you get on, and if any specific error messages appear when you try sending a move goal in the utm frame, post those as well since that might help debug the problem. I tried this out and it worked!
