Somehow, the DXL bus shut down at or after the first turn of the Robomagellan event.
Timeout talking to the servos, no ability to turn, no ability to turn on torque after re-starting.
Multimeter still showed 5V on the TTL wire and 12V on the power wire, so I don't quite know what it is yet.
(Haven't yet analyzed the log files or hooked up the scope, so we'll see what it is.)

Robots are hard.

Still beats my brother's weekend. He broke out in rash/hives all over his arms and back not long after getting home from seeing the new Avengers movie on Thursday. Got his usual allergy shot (mostly for dust mites) and a short course of Prednisone on Friday which made things better, but then woke up Monday morning with his hands and lips red and swollen. Not certain about the first attack other than being something transfered from the seat when he was in the theater, but ground beef seems the likely culprit for the latter attack since he made burgers bare-handed on Sunday and ate them for lunch and dinner.

That sucks.

Ground beef can give you swollen lips and hands? Crazy.

It can when you have developed an allergy to galactose-alpha-1,3-galactose (alpha-gal), which can be triggered by - among other things - a lone star tick bite. If it really is alpha-gal allergy, then I won't have to expect family members wasting any more money on beef or pork since all mammalian meat becomes off-limits.
