利用turtlebot 的导航配置文件
由于movbase发的速度太不友好了所以使用了ros自带的滤波安装相应的包
apt-get install ros-indigo-yocs-velocity-smoother
我的配置文件 standalone.yaml
# Example configuration: # - velocity limits are around a 10% above the physical limits # - acceleration limits are just low enough to avoid jerking # Mandatory parameters speed_lim_v: 0.8 speed_lim_w: 5.4 accel_lim_v: 0.3 accel_lim_w: 3.5 # Optional parameters frequency: 20.0 decel_factor: 1.0 # Robot velocity feedback type: # 0 - none # 1 - odometry # 2 - end robot commands robot_feedback: 2
