ROS2测试仿真

电脑配置：R7-7840H 核显
结论：turtlebot3 运行失败。
turtlebot4 可以进入仿真环境，但是无法操作。
现在在用 ign gazebo 驱动简单的差分机器人

ign gazebo

采用ign gazebo 打开简单的差分机器人

安装

sudo apt-get install ros-${ROS_DISTRO}-ros-gz
sudo apt install ros-humble-gazebo-ros-pkgs 

# 桥接器 用于 ros2与gazebo Transport 之间交换信息
sudo apt-get install ros-humble-ros-ign-bridge

# 接受键盘信息并转为 twist
sudo apt-get install ros-humble-teleop-twist-keyboard

运行

# 运行仿真
ign gazebo -v 4 -r visualize_lidar.sdf

# 查看话题
ign topic -l

# 为/model/vehicle_blue/cmd_vel 创建桥接器
ros2 run ros_gz_bridge parameter_bridge /model/vehicle_blue/cmd_vel@geometry_msgs/msg/Twist]ignition.msgs.Twist

# 键盘控制节点
ros2 run teleop_twist_keyboard teleop_twist_keyboard --ros-args -r /cmd_vel:=/model/vehicle_blue/cmd_vel

# lidar创建桥接器
ros2 run ros_gz_bridge parameter_bridge /lidar2@sensor_msgs/msg/LaserScan[ignition.msgs.LaserScan --ros-args -r /lidar2:=/laser_scan

turtlebot3

gazebo 启动问题
export SVGA_VGPU10=0

export GAZEBO_MODEL_PATH=${GAZEBO_MODEL_PATH}:/home/ly/.gazebo/models

# 设置TurtleBot3模型
export TURTLEBOT3_MODEL=burger

# 启动TurtleBot3 World环境
ros2 launch turtlebot3_gazebo turtlebot3_world.launch.py

turtlebot4

gazebo 启动问题
export SVGA_VGPU10=0

# 仿真launch
ros2 launch turtlebot4_ignition_bringup turtlebot4_ignition.launch.py 

# 键盘控制节点
ros2 run teleop_twist_keyboard teleop_twist_keyboard
