Gazebo drive-to-pose-controller demo

DriveToPoseController plugin is a simple proportional controller that is attached to a model
entity to move it by giving a pose in Gazebo's world coordinate system. This is not a
standalone plugin, and requires the DiffDrive and OdometryPublisher plugins respectively.

The plugin has the following tags:

`<linear_p_gain>` - (Optional) Proportional gain for the linear velocity controller. Default: 1.0
`<angular_p_gain>` - (Optional) Proportional gain for the angular velocity controller. Default: 2.0
`<linear_deviation>` - (Optional) Allowable linear deviation (in meters) from the desired coordinate. Default: 0.1
`<angular_deviation>` - (Optional) Allowable angular deviation (in radians) from the desired orientation. Default: 0.05

Sending commands to the robot to navigate it through the industrial warehouse

1) Send the robot to the first pose in the warehouse, [x, y, orientation] = [1.78, -9.4, -3.14]

gz topic -t "/model/DeliveryBot/cmd_pose" -m gz.msgs.Pose_V \
-p "pose:[{position: {x: 1.78, y: -9.4, z: 0.0}, orientation: {x: 0.0, y: 0.0, z: -0.99, w: 0.0}}]"

NOTE: Each time the robot reaches the desired pose, it will send a pose acknowledgement
on the topic /model/<model_name>/reached_pose.

2) Send the robot to the second pose, [x, y, orientation] = [-3.75, -9.4, 1.57]

gz topic -t "/model/DeliveryBot/cmd_pose" -m gz.msgs.Pose_V \
-p "pose:[{position: {x: -3.75, y: -9.4, z: 0.0}, orientation: {x: 0.0, y: 0.0, z: 0.707, w: 0.707}}]"

3) Send the robot to its third pose, [x, y, orientation] = [-3.75, 9.18, 3.14]

gz topic -t "/model/DeliveryBot/cmd_pose" -m gz.msgs.Pose_V \
-p "pose:[{position: {x: -3.75, y: 9.18, z: 0.0}, orientation: {x: 0.0, y: 0.0, z: 0.99, w: 0.0}}]"

4) Send the robot to its final pose, [x, y, orientation] = [-5.9, 9.18, 3.14]

gz topic -t "/model/DeliveryBot/cmd_pose" -m gz.msgs.Pose_V \
-p "pose:[{position: {x: -5.9, y: 9.18, z: 0.0}, orientation: {x: 0.0, y: 0.0, z: 0.99, w: 0.0}}]"

This plugin is loosely based on the control schemes introduced in Chapter 4 (pp. 130-142) of
Robotics, Vision and Control by Corke, Jachimczyk and Pillat and it can be found at:
https://link.springer.com/chapter/10.1007/978-3-031-07262-8_4

When I ran the example, Gazebo launched successfully and the UI loaded but the simulation area remained blank. I found that removing this plugin block from the world file resolved the issue. Not sure why this happened or if it was just an isolated issue on my end, but thought it was worth mentioning.

I believe this is due to the behavior in Harmonic for default plugins mentioned here. If that is the case it should actually be OK to not have the plugin defined in both Ionic and Harmonic, can you give that a quick try if possible? Then I guess a solution could be to:

  • Open a PR to gz-sim9 that removes the Physics plugin.
  • Backport both that PR and this to Harmonic.

Yes, removing the <plugin> tag should do it. I'd recommend removing the <gui> tag as well unless you have a specific reason for not using the default gui config.
