由于我不熟悉这个机器人的代码逻辑以及操作方式，所以有一下几处问题需要具体的回答：
1.不关闭screen的情况下，去BEAR的window看看有什么具体报错没有；
2.在没有任何程序运行的情况下，可以尝试Util/test_BEAR来看看BEAR是否有通信问题。
请问这两个步骤的具体代码命令是什么？

1.Turn on the power, and the LED lights on the motor are both red and green.
2.When I type the following command：python3 -m Startups.run_bear，I get the following result：Pinging BEAR 01…
3.By the way, Will reversing the polarity of the power supply cause this kind of malfunction?

The problem now is that the legs cannot be initialized and stand, the arms can be initialized. So, is the motor in the leg broken?

[ZhongLe Zhao]

The result is the same. I don’t know why. Is it possible that the motor in the leg is broken?
