我目前在高中的 AP 计算机科学课上。我们使用“kareltherobot”包在 Java 中编码。以下是说明：对于这个实验室，我们的机器人将像一个 Roomba 一样工作。它会拾取房间里所有的蜂鸣器。它会在执行任务时跟踪信息。它必须清理房间中的每个位置。必须提示用户清洁房间（要读入的世界文件）以及机器人初始状态的位置和方向。

反馈给用户的信息：

• 房间面积

• 桩数

• 蜂鸣器总数

• 最大的蜂鸣器堆

• 最大桩的位置（相对）

• 平均桩大小

• 脏污百分比（堆/面积）

我提供了一个模板和一个世界来测试。因为我们正处于学习编程和测试的初始阶段，所以我正在提供测试世界。考虑可能破坏代码的测试用例，并在开发过程中尝试测试这些用例是个好主意。

这是我当前的代码。我的问题是我无法让机器人去东南角。我试图让它去那里然后让它移动并使用方法清洁行。这样，它将一一清洁每一行。有人可以帮帮我吗？
