Tested on Ubuntu 16.04.1, ROS Kinetic and using Gazebo 7.
These packages are used to simulate the flying robot Ardrone in ROS environment using gazebo simulator. Totally they are 4 packages. Their functions are descript as below:
-
cvg_sim_gazebo: contains object models, sensor models, quadrocopter models, flying environment information and individual launch files for each objects and pure environment without any other objects.
-
cvg_sim_gazebo_plugins: contains gazebo plugins for the quadrocopter model. quadrotor_simple_controller is used to control the robot motion and deliver navigation information, such as: /ardrone/navdata. Others are plugins for sensors in the quadrocopter, such as barometer sensor.
-
message_to_tf: is a package used to create a ros node, which transfers the ros topic /ground_truth/state to a /tf topic.
-
cvg_sim_msgs: contains message forms for the simulator.
Some packages are based on the tu-darmstadt-ros-pkg by Stefan Kohlbrecher, TU Darmstadt.
How to run a simulation:
-
Install dependencies:
- Hector quadrotor: As an example you can install all hector suite running
sudo apt-get install ros-<your_version>-hector-*
- ardrone_autonomy: run
sudo apt-get install ros-<your_version>-ardrone-autonomy
- Hector quadrotor: As an example you can install all hector suite running
-
Download this
tum_simulator
package. -
Build packages with
catkin_make
in the workspace root folder. -
Start a ros master by typing the following command in console:
roscore
-
Run a simulation by executing a launch file in cvg_test_sim package:
roslaunch cvg_sim_gazebo ardrone_testworld.launch
-
You can manipulate the quadrocopter in gazebo simulator by downloading the ardrone_helpers package and using a joy-stick after calling this command:
roslaunch ardrone_joystick teleop.launch
Information for manipulation via joystick:
-
The
L1
button starts the quadrocopter. It also works as a deadman button so that the robot will land if you release it during flight. -
The left stick can be used to control the vx/vy-velocity. Keep in mind that these velocities are given in the local frame of the drone!
-
The right stick controls the yaw-rate and the altitude.
-
The select button can be used to switch between the two cameras. This can also be done by executing
rosservice call /ardrone/togglecam
.
