movebase导航

2024-08-19 09:09:43   223人阅读

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
