ESD protection construction

A thing has recently come to mind.
I, a private organization, have a close affiliation with a school team. Recently, the school team has had 2 ports and 1 motor die. The interesting thing is that I have had absolutely no problems at all despite driving my robot more and for longer periods of time, on the exact same field.
This leads me to believe that construction may play a crucial factor in the burning out of ports and motors.
So I now ask you, could you share images of your bots (past and current seasons as well as prototypes) and what kind of problems you’ve had with the electronics? (If you’re comfortable with leaking)
Also please explain and theorize as to why this might be.


2 ports and one motor is not significantly different enough that you can’t wave it off as just chance, but your construction can have an impact. All of your components need to be electrically connected, or charges will build up and then discharge through your cables and ports.


Could you elaborate on what you mean by electrically connected?

Also while this incident number is small, I’ve heard of teams that have suffered numerous problems while other teams have had none, which I find rather strange. Even though these incidents are across different regions, the fact that esd incidents are inconsistent means that there must be a determining variable that causes esd issues.
Right now I am unsure as to what that variable might be, but I am almost certain there is one

Basically metal contact throughout the entire robot. This gives electricity ways to flow, preventing buildups between parts.


Hmmm, I see now.
The school team’s robots had hard stops on the midpoint of their arms. My robot had hard stops on the front of the arms right where the intakes were. All of their issues were with their intakes.
