First time creating topic, sorry for format. This thread involves a problem my team has faced practically all season. It involves frying ports on multiple cortex’s. First V5 brain mess up : The problem began a couple months go when I finally completed all the code for the robot. I completed all th…

[image] jdg2nd: With all of this being said it seems as though the code is some how causing the issues, since the likelihood of getting 2, even 1 faulty cortex, is very slim. We are sending one of the cortex’s into vex, any suggestions are helpful! If I had to guess based on the prior statist…

My team had three blown ports during the same practice session. I am pretty sure the issue is ESD (electro-static discharge). We were able to develop a solution that seems to have solved the problem. All three of our blown ports were connected to a motor on the end of a lift. If you look closely at…

[image] teresajude: The key, from a rule standpoint is that the braid / sleeve is covering and managing your cables, as well as protecting them from static discharge. This is within the spirit and the text of <R7> f. Hmm, not sure I agree: If a product is being used to both wrap/manage cabl…

The product is NOT being used to connect the cables electrically to the robot structure. The product is being used to provide an alternate electrical pathway to PROTECT the cables from static discharge. Remember, the rule is for the purpose of cable PROTECTION, organization or management. The only…

Your interpretation of this may be overly broad - ask Q&A if you wish official answer. The examples in the past have been about mechanical protection of cables. Also, in the past electrical modification has been prohibited. Your assertion is interesting and worthy of Q&A to clarify what protecti…

Why would GDC want to insist that using conductive wire sleeve that connects robot subsystems is an illegal electrical modification which needs to be prohibited? Does VEX enjoy writing off monetary losses from replacing all the ESD damaged V5 Brains that are still covered under warranty? That woul…

[image] Uncontrollable spinning wheel and Fried ports OFFICIAL Tech Support Background : Since my last post, we sprayed down the robot as well as the field with static guard. After this the robot worked perfectly fine for about a week. Eventually our left intake motor li…

Did anyone figure out a way to completely secure the ports from getting static build up? Reading through this thread has shown that there is still a chance of getting the port blown out. Is there a definite answer to how to stop the static build up, other than a theory?

It is static. People can have this problem and this year when all those cubes go up a tray can cause major static and blow motors and even if its bad the whole brain.

your best options for solving static issues: keep your robot grounded together. that means you shouldn’t have any electronically isolated parts of your robot. this will prevent buildup of different charges in different parts of your robot. the most common example of isolated systems is your arms.…
