根因分析

在启动 Gazebo 仿真之前，TURTLEBOT3_MODEL 环境变量未设置或设置为无效的模型名称（例如 'burger'、'waffle'、'waffle_pi'）。

English

The TURTLEBOT3_MODEL environment variable is not set or set to an invalid model name (e.g., 'burger', 'waffle', 'waffle_pi') before launching Gazebo simulation.

解决方案

  1. export TURTLEBOT3_MODEL=burger
  2. 将导出命令添加到 .bashrc：echo 'export TURTLEBOT3_MODEL=burger' >> ~/.bashrc && source ~/.bashrc

无效尝试

常见但无效的做法:

  1. 95% 失败

    The launch file reads TURTLEBOT3_MODEL at startup; without it, no robot URDF is loaded.

  2. 90% 失败

    Only 'burger', 'waffle', 'waffle_pi' are valid; typos or unsupported models cause spawn failure.

  3. 80% 失败

    The environment variable must be set in the same shell session before launch, not sourced from a different workspace.
