CAN uses differential signals, meaning two lines are used for signals. There is no clock, similar to UART. This is useful for transmission over cable, as devices can be at different grounds and still communicate over the network.
I2C uses two lines also, but in this case one is for the signal, the other is for the clock. This is useful for use on a PCB where all IC are connected to the same ground.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
