Hello,

When installing the arm, I noticed that there is no idle, the servo rotates 360 degrees.
Is that correct?

The screw in the servo bag for the arm is also too short.

After switching on nothing happens, the blue LED lights up briefly, you can hear a slight click.

Please help

Hi Gregor:

 What Assembly guide are you following to set everything up? The right one is this: https://www.jjrobots.com/b-robot-evo-2-assembly-guide-v1-2/

 Have you tried to debug the process connecting the DEVIA control board to the computer via USB cable and opening the Arduino IDE serial port? What do you see in the verbose window? 

The blue led blink is normal, that means the power is fine. That led belongs to the WIFI module and only blinks once when it receives the proper current and voltage.

Hi,

Thank you, I will look at the instructions from the link, and I am sure that everything is connected correctly, because the board also shows what I got in the instructions.
I just don’t understand this statement about the neutral point of the servo, as it can be rotated 360 degrees.
Where can I find this Devia control board software, I would like to point out that I am not using Windows, but Mac OS.
Please answer

Yes, I used this video, with a different board in the video, but the pictures of the connections are those of my board.

would like to point out that one of the motors with paint damage, so probably used.

Connect the robot to the computer using the USB cable and launch the Arduino IDE serial monitor. Then start the b-robot and check the verbose. What do you see?

The servo can be set properly later. Disconnect if for now. Just to narrow down the problem

I can’t get any further, after connecting the window looks like this, see picture 1.
When I try to upload an error message appears, see picture 4

It’s just not fun anymore, I didn’t do anything wrong with the assembly.
I have been struggling for two days to get it running, apart from the fact that I am now struggling with an English-language Arduino software that I cannot master with my basic English.
According to information, however, I ordered an item that should work after assembly without any programming knowledge.

Hi Gregor

 In order to open the SERIAL MONITOR port you do not need to upload any code. The DEVIA was sent already programmed. Just connect the B-robot to the computer and click on the Arduino IDE SERIAL MONITOR. Let me know what you see.

nothing happens, just on empty window.
whereby it would be good to know whether it should happen when it is switched off or when it is switched on

Do you still want to help me in any way, or should I return the item?

Thanks

@gregor-wollnik The thing is , it looks like you have already uploaded another code to the DEVIA control board Gregor. That makes mandatory to reupload the original code to the DEVIA and check the SERIAL MONITOR verbose. To do that, please do as below:

 

HOW TO UPLOAD the ARDUINO CODE to the DEVIA CONTROL BOARD

(Skip this step if you got the Plug & Play B-robot EVO kit version. The Arduino is already programmed)

a) Install the Arduino IDE on your PC from here (skip this step if you have the Arduino IDE already installed) This B-robot code has been tested and developed on IDE version 1.6.5 and later versions. If you have a problem compiling the code, let us know

b) Download all the arduino files from here . Copy the files inside the BROBOT_EVO2_23_M0 folder in your hard drive  

c) Compile and send the code to the DEVIA control board:

  1. Open your Arduino IDE
  2. Open the main code in /BROBOT_EVO2_23_M0/BROBOT_EVO2_23_M0.ino
  3. Connect your DEVIA board with the USB cable to the PC
  4. Note: If this is the first time you connect an Arduino board to your PC maybe you might need to install the driver.
  5. Select the board Arduino/Genuino ZERO (native USB port). In the TOOLS menu->board
  6. Select the serial port that appears on the tools->Serial port
  7. Send the code to the board (UPLOAD button: Arrow pointing to the RIGHT)
upload
Selecting the right board
Selecting the right board before uploading the code

 

d) Done!
