Good Afternoon Community! I'm making slow but steady progress on rebuilding my Hero-1. I have a question:
Has anyone run in to issues mounting a EZ-B4 vertically?
See the attached photo.
I've looked at all the EZ robots...all are horizontally mounted. From what I can see, the power connector and the magnets are the only "things" holding the processor in the base. I'll have to come up with a way to secure the processor in the base so it doesn't vibrate out.

Ok...Let's try this again https://www.ez-robot.com/emicons/emo_smile.gif
Ok Got it Thanks! Greg
I duct tape mine around the base to keep secure in InMoov and other rough duty project. I also use heavy duty Velcro to keep entire unit intact especially when using Sabretooth, loss of unit the robot keeps on going.
@jackphillips1953 - what I am hearing is you need a "signal loss self smarter" so as to make the robot no crash - no go boom!
What is "signal loss self smarter" or just a joke?
As all have said, no real problems with mounting the EZR controller vertically. THe magnets seem to keep mine secure enough in use. Tape is a simple solution as outlined above.
I did design a simple adapter that allowed me to mount it while still allowing access to the fuse if it blows.

>"signal loss self smarter"
Yes I was half joking and half revisiting an idea others have tossed around before.
Like you said, if you lose your ezb your robot keeps going and on a large robot that's not great because you're going to damage your robot or your house or your self, etc.
Secure mounting methods are the easiest way and probably cover most scenarios.
Some heavy duty robots or robot builders might want a some sort of signal lose or "heart beat" monitor. I wonder if there is such a thing in the R/C world?
Justin,
I know about runaway robot. Not fun. I guess no solution to this.
My 2 cents on the "signal loss" issue... There's a concept in high reliability control electronics called "Fail Safe" design. The idea is, that if the main processor goes south, or fails... control lines are pulled to a safe state by discrete components. For example.. a trigger wire from the a processor turns on a motor...active high trigger. A pull-down resistor.. maybe 5k to gnd would be used..so the line is pulled low if the processor loses power... stopping the motor. Another example is if an E-stop gets pulled.....the machine isnt allowed to just start up again, unless a safe power up sequnce happens. There's a whole science to it referred to as SIL levels...(SiL)...Nuke power plants have highest level, SIL 4 -Greg
