Electric board 5618

This electric board is designed to fit on almost every robot.

CAD files are on this link:

Re: Electric board 5618

What advantages do you see of this design over a board designed specifically for the robot itís going on?

Re: Electric board 5618

Oliver, I like that you centrally locate the PDP to minimize wire run length to high current motor controllers.
Please keep in mind that the breakers and wire on the PDP must be visible for inspection when considering your designs.

Re: Electric board 5618

While the design is very compact, it creates some manufacturabilty, serviceability and durability issues. That is always the price one must be willing to pay for using compact arrangements like this. In industry, hinged panels are used only as a last resort.


It would be best if you can make a mock up of your design using sheets of cardboard. Include all the wiring. See how the other team members like working with it; the poeple who will build it, the programmers, the pit crew and Robot Inspectors.



Unless you use very flexilbe wiring and secure the wiring in just the right way, the panels with the motor controllers might become difficult to move.



In your current design, there might not be sufficient bend radius for the 6 AWG wires coming from your battery and breaker, even if you use the very flexible types of wire. It would also be best if the 6 AWG wires could be secured to the panel, especially if you intend for this whole assembly to be removable from the robot.


It would be best to secure the input and output wires of all your motor controllers to the panels that the motor controllers are mounted on. Otherwise, you can damage the wires where they exit the case of the motor controllers as you open and close those panels. Such damage is likely to (initially) manifest it self as intermittent open circuits. Please note that the motor controllers do not have strain reliefs or grommets on any of the wires. Any damaged wires will have to be replaced by opening up the case and soldering on new wires.



Currently, there are no breakers installed in the PDP. Is there sufficient space between the PDP and the motor controllers to accomodate the breakers and the wiring from the motor controller outputs to the motors? Will the wiring be pinched?



How will it be possible to inspect the breakers?



The motor controllers have diagnostic LED's that will not be visible when the panels are in the closed condition. Is this acceptable to your programming team?


The panels that the VRM and PCM are mounted on are not very wide. Is there sufficient access to inspect your wiring and make changes to the wiring if this assembly is mounted on a larger panel? If this assembly is to be removable from the robot, all the wiring to and from the VRM and PCM must be secured to the panels to avoid damage.
