Re: Faulty Jaguars (CAN)

All Jaguars have been tested individually. The crooked light Jaguar functions properly, but the LED is still a manufacturing defect.

One of our mentors built a device similar to a network cable tester to test CAN cables, and we verify the correct wiring of each cable we make before using it.

All IDs have been assigned properly, and we label each Jaguar with its assigned ID. Through individual testing we have also ensured that each Jaguar has a unique ID. None of our Jaguars have been assigned an ID of 1, in case you were wondering.

By "Yes", I mean proper LED functionality. It blinks amber when there is no communication, and is solid amber when BDC-COMM is running, as well as the applicable green LED when assigning IDs.

All of our Jaguars have been bench tested before being put on a robot, and the DOA Jaguars have not worked at all since the beginning. As for the ones that failed later on, Jaguars that we put on the robot as replacements for ones that have gone bad have not experienced the same issues as the failed Jaguars, so I doubt that it was an issue with reversed polarity.

We also doubt that our batteries have been wired improperly. We've been using batteries from years past, which have been used on other robots many times before with no issues.
