I have found that the connection board on top of the Arduino uno contains faulty connecters.
One of the Infrared modules is not getting connection and also the battery connection does not seem to work although the two batteries are fully loaded.
Just wondering if anybody else has seen this problem and was able to get this connection board replaced from Lafvin.
My kit was good. If you believe your board is not working, contact Elegoo.
Which connectors are trouble? The Elegoo drawing was not complete, here is what I found with my working kit:
Multiple topics, same subject.
Just maybe an ignorant question.
Should the blue Light on both ir modules be on when the robot is powered up?
If the there is error on the board,
Also it looks that the battery connection is not working. When i switch the robot on nothing happens although both batteries are fully loaded.

That will probably mean "something detected." You have five IR modules. Two for forward looking, two for line sensing and one for the remote control (D3 on my updated LAFVIN drawing). You also have a blue LED between A1 and A2 indicating "forward" motor movement (green indicating reverse).
Show a picture of the LED.
The metal on the springs on the battery housing might be tarnished. "Roll" the batteries in the housing to try to scrape through any tarnish.
