Behavior Tree example for ROS1
- git clone the repo.
mkdir -p ~/ros1_bt_ws/src
cd ~/ros1_bt_ws/src
git clone https://github.com/Adlink-ROS/BT_ros1.git
- Install dependencies
cd ~/ros1_bt_ws
rosdep install --from-paths src --ignore-src -r -y
- Build
catkin_make
# If you want to build with OpenVINO support
catkin_make --cmake-args -DBUILD_OPENVINO=ON
We use NeuronBot2 as example. We will run Gazebo with NeuronBot2 and show a simple BT example.
The BT example (refer to bt_nav_mememan_interrupt.xml) will make NeuronBot2 move between Goal_a and Goal_b.
If receiving /interrupt_event, which is gohome, then NeuronBot2 will move to Goal_c.
- Open 1st terminal and run mememan world. (melodic environment)
source ~/neuronbot2_ros1_ws/devel/setup.bash
export GAZEBO_MODEL_PATH=~/neuronbot2_ros1_ws/src/neuronbot2/neuronbot2_gazebo/models
roslaunch neuronbot2_gazebo neuronbot2_world.launch world_model:=mememan_world.model
- Open 2nd terminal and run navigation. (melodic environment)
source ~/neuronbot2_ros1_ws/devel/setup.bash
roslaunch neuronbot2_nav neuronbot2_nav.launch map_name:=$HOME/neuronbot2_ros1_ws/src/neuronbot2/neuronbot2_nav/maps/mememan.yaml open_rviz:=true
- Open 3rd termainal and run BT. (melodic environment)
source ~/ros1_bt_ws/devel/setup.bash
rosrun bt_sample node _file:=$HOME/ros1_bt_ws/src/BT_ros1/bt_xml/bt_nav_mememan_interrupt.xml
- Open 4th terminal and pub interrupt event. (melodic environment)
