Crazyswim

Post by brod »

After an accidental custom firmware bug causing the crazyflie to use full thrust for 25.2 seconds and eventually falling to the ground (aka, the pool) my crazyflie is back up and running without a hitch! The custom firmware also shut down the crazyflie after the 25.2 seconds which I assumed had a massive impact on the board not frying. The crazyflie swam roughly 1.2m deep before being scooped up.

My instructions for what to do if your crazyflie goes underwater.
Probably have no technical benefit although it worked for me :D
  • 1. Pull it out asap
  • 2. Disconnect Battery
  • 3. Pad dry it
  • 3. Wait 10 minutes or until your patience holds out (24-48hours is probably recommended)
  • 4. Reconnect Battery
  • 5. Check console logs for broken parts
  • 6. Fly somewhere safer
I'm currently helping a friend manufacture a semi perspex / semi heatshrink enclosure which should make the fly watertight ex- the motors.
eBay link when complete, probably AUD$2 - $3

Maybe you should be the one to first develop an underwater vessel with the Crazyflie ;). Often water doesn't damage the electronics that much if it is well cleaned afterwards. The battery is often the week point.
