好的,以下是使用xacro编写一个正方体底座、两个驱动轮和两个万向轮的代码:
```xml
<?xml version="1.0"?>
<robot xmlns:xacro="http://ros.org/wiki/xacro" name="robot_base">
<!-- Define the dimensions of the square base -->
<xacro:property name="length" value="0.5"/>
<xacro:property name="width" value="0.5"/>
<xacro:property name="height" value="0.1"/>
<!-- Define the base link -->
<link name="base_link">
<visual>
<origin xyz="0 0 0" rpy="0 0 0"/>
<geometry>
<box size="${length} ${width} ${height}"/>
</geometry>
<material name="white">
<color rgba="1 1 1 1"/>
</material>
</visual>
</link>
<!-- Define the left drive wheel -->
<joint name="left_wheel_joint" type="continuous">
<origin xyz="-0.25 0 -0.05" rpy="0 0 0"/>
<parent link="base_link"/>
<child link="left_wheel_link"/>
<axis xyz="0 1 0"/>
</joint>
<link name="left_wheel_link">
<visual>
<origin xyz="0 0 0" rpy="0 0 0"/>
<geometry>
<cylinder radius="0.1" length="0.05"/>
</geometry>
<material name="red">
<color rgba="1 0 0 1"/>
</material>
</visual>
</link>
<!-- Define the right drive wheel -->
<joint name="right_wheel_joint" type="continuous">
<origin xyz="0.25 0 -0.05" rpy="0 0 0"/>
<parent link="base_link"/>
<child link="right_wheel_link"/>
<axis xyz="0 1 0"/>
</joint>
<link name="right_wheel_link">
<visual>
<origin xyz="0 0 0" rpy="0 0 0"/>
<geometry>
<cylinder radius="0.1" length="0.05"/>
</geometry>
<material name="red">
<color rgba="1 0 0 1"/>
</material>
</visual>
</link>
<!-- Define the left castor wheel -->
<joint name="left_castor_joint" type="continuous">
<origin xyz="-0.25 0 0.05" rpy="0 0 0"/>
<parent link="base_link"/>
<child link="left_castor_link"/>
<axis xyz="0 1 0"/>
</joint>
<link name="left_castor_link">
<visual>
<origin xyz="0 0 0" rpy="0 0 0"/>
<geometry>
<sphere radius="0.05"/>
</geometry>
<material name="gray">
<color rgba="0.5 0.5 0.5 1"/>
</material>
</visual>
</link>
<!-- Define the right castor wheel -->
<joint name="right_castor_joint" type="continuous">
<origin xyz="0.25 0 0.05" rpy="0 0 0"/>
<parent link="base_link"/>
<child link="right_castor_link"/>
<axis xyz="0 1 0"/>
</joint>
<link name="right_castor_link">
<visual>
<origin xyz="0 0 0" rpy="0 0 0"/>
<geometry>
<sphere radius="0.05"/>
</geometry>
<material name="gray">
<color rgba="0.5 0.5 0.5 1"/>
</material>
</visual>
</link>
<!-- Define the robot -->
<robot>
<link name="base_link"/>
<joint name="left_wheel_joint"/>
<link name="left_wheel_link"/>
<joint name="right_wheel_joint"/>
<link name="right_wheel_link"/>
<joint name="left_castor_joint"/>
<link name="left_castor_link"/>
<joint name="right_castor_joint"/>
<link name="right_castor_link"/>
</robot>
</robot>
```
这个代码会创建一个名为 "robot_base" 的机器人,其中包含一个名为 "base_link" 的正方体底座。机器人还包含两个驱动轮(名为 "left_wheel_link" 和 "right_wheel_link")和两个万向轮(名为 "left_castor_link" 和 "right_castor_link")。驱动轮和万向轮的位置可以通过修改 "xyz" 属性来调整。
