Greg,
I haven't done any real testing, but it does not appear that any sort of safety kicks in after 100ms in Java. Our robot definitely moved for more than 100ms with our sleep() calls.
You made me curious, though, so I started poking around. The Jaguar class extends SafePWM, which indeed defaults to disabling safety:
Code:
void initSafePWM() {
m_safetyHelper = new MotorSafetyHelper(this);
m_safetyHelper.setExpiration(0.0);
m_safetyHelper.setSafetyEnabled(false);
}
This sounds rather silly for a class billed as "SafePWM" to me, though it does expose methods for you to enable safety if you wish.
