您可以使用ROS中的move_base模块来实现在python文件中调用move_base。具体步骤如下:
1. 导入必要的ROS包和模块:
```
import rospy
from move_base_msgs.msg import MoveBaseAction, MoveBaseGoal
from actionlib import SimpleActionClient
```
2. 初始化ROS节点:
```
rospy.init_node('move_base_python')
```
3. 创建一个SimpleActionClient对象:
```
client = SimpleActionClient('move_base', MoveBaseAction)
```
4. 等待move_base服务器启动:
```
client.wait_for_server()
```
5. 创建一个MoveBaseGoal对象,并设置目标点的坐标和姿态:
```
goal = MoveBaseGoal()
goal.target_pose.header.frame_id = "map"
goal.target_pose.pose.position.x = 1.0
goal.target_pose.pose.position.y = 2.0
goal.target_pose.pose.orientation.w = 1.0
```
6. 发送目标点到move_base服务器:
```
client.send_goal(goal)
```
7. 等待move_base完成导航:
```
client.wait_for_result()
```
以上就是在python文件中调用move_base的基本步骤。
