  1. Watchdog timers before the mystery rebootYour microcontroller will lock up eventually. A properly configured watchdog catches silent failures before they become field support calls.
  2. State machines that survive the prototypeFinite state machines aren't academic ceremony—they're how you keep firmware predictable when inputs misbehave and timers collide.
  3. Sensor calibration you'll actually run twiceMost calibration routines gather dust in a comment block. Here's how to build the kind you'll invoke before every demo without groaning.
  4. Closed-loop or cosplayIf the robot cannot sense the thing it claims to control, it is performing robotics.
