Communication between Dobot and Arduino


Hello everybody,
i got a really important question.

Is there a good way to communicate between the Dobot and the Arduino?
I’ve seen that there’s a rx and tx pin in the bottom of the Dobot but is it possible to use those pins? Or is it possible that there’s a SDA or SCL pin?

We just improvised a communication protocol, but the problem is that there’s a delay of 200ms while sending a single bit…


Are you working on “6) Arduino Demo based on communication protocol (arduino mega board)” from “Dobot Demo v2.0” from: ?
