How to communicate with Dobot using raw protocol


#21

It is for a work project and it is currently weekend after the weekend I will send the communication string I used.

when I am done with the project I can probably also send a java library to control the Dobot in java if you need.

OK, thank you very much

for some reason it still not working it give me 2 types of return because also tried another hex value.

Your hex for Set DeviceWithl: AA AA 04 03 02 01 00 FA (Version 1 slider)
It give me the following return: AA AA 0A 03 02 00 00 00 00 00 00 00 F9

If I use the following command it give me another return:
My hex for Set DeviceWithL: AA AA 04 03 01 01 00 FB
It give me the following return: AA AA 02 03 01 FC

And for some reason the slider rail is not moving when I give it a set point can you give me a working communication string. Because I made my own but it only give a sound like the motors get power but and it don’t move or do any other commands.

I also made some attempts for that. Unfortunately, it has not yet made it work properly. I sent a message to the relevant person for help, hoping that they can guide the user in the specific operation process.

Regarding the conveyor belt, how do you make it work normally through the communication protocol? I want to know the specific process. Could you please explain it in detail, thanks

I also want to know how to make the slide rail move according to the communication protocol. I tried to send the following hexadecimal HEX in sequence, but nothing happens on the slide rail.

  1. Set the device slide rail status (Set DeviceWithL): AA AA 04 03 02 01 01 F9
  2. Get the jog parameters of the slide rail (GetJOGLParams): AA AA 02 4A 00 B6
  3. Get the slide rail L jog parameter and return: AA AA 0A 4A 03 00 00 00 1E 00 00 00 32 63
  4. Execute the point function with slide rail (SetPTPWithLCmd): AA AA 17 56 03 01 00 00 7A 43 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 F4 F4

Currently fixing some problems i have with my other dobot first because i need them up and running put for some reason all stepper motors broke and don’t turn anymore. When i handled that i will go to my test system to send you the hex code i used sorry but forgot it when i was there this morning
