Solving attempt 1:
Change settings in
I also designed a second PCB, the RGB Button circuit, but that one had the same issues.
Solving attempt 2:
Change sizes of pictures using Incscape
Solving attempt 3:
My instructor informed me that another student had the same issues. He just went ahead and milled it anyway and it worked.
I find this very weird but worth noting down.
Solving attempt 4:
My instructor noticed there was an extra line around the PCB. Through the offset of 4 that line becomes thicker than the edgeCut line.
Therefore: remove that line.
Decreasing the amount of RFID modules would considerably simplify the hole system. Likewise, it would not be necessary to use the Pico microcontroller. Instead, a XIAO could be used. Additionally, the cost of the robots would decrease.
In combination with a 3D magnetic sensor the exact position of all surrounding robots could be precisely determined and even differentiated with other objects without major inconveniences in the internal coordinate system. For this, it is necessary that the hall/ magnetic sensor can register RFID waves. Whether this is the case is still to be determined. I am in contact with a professor from TU Ilmenau university to consult this topic.
