Andrew, the Hammerhead allmost incident was cleared out, after the 2 idiots driving RC cars next to the hangar stopped. They where spot on Hammerheads frequency.

That is something no roboteer ,with 700 safetydevices and a battery of precaution can prevent.

Also, my reaction about degrees in several engineering fields,was just a reaction on Mr Plants remarks that a lot of us roboteers are basicly seen so incompetent that we are even a danger basketweaving.
I do not see it mandatory. The only thing I want to see is robots that are build, and can be operated inside the rules ,as safe as possible,as long the people using them are no morons of total idiots treating the robots as a cheap toy car.
