但在Grex的系统内，水下机器人将充当一个中继站，将来自母船的控制信号传给连网的其他机器人，这种方式下的传输距离可达到数英里。

But in the Grex system, vehicles will be able to act as relay stations, bouncing a control signal from the mother ship to the networked submarines over many miles.

使用信号／插槽以灵活且可维护的方式控制对象间通信要比使用脆弱的回调风格容易得多。

With signals/slots, it is much easier to control communications between objects in a flexible and maintainable manner than it is with a fragile callback style.

该控制方式的指令信号通过同时检测电源电流和负载电压得到。

The reference signal in this control approach is obtained by detecting both source current and load voltage.
