Underwater ROV with Lego Mindstorm and communicating via Xbee


#1

Thanks to Make blog I just bumped into this ROV which is made with Lego Mindstorm parts. Looks really cool.

Good inspiration from this video is:

  • Number of motors: it has 4 motors working like a quadcopter to keep it from sinking (doesn't seems it has a neutral buoyancy) and to change it's attitude (nose down, nose up), and then 2 motors to move forward and rotate it.
  • Propellers: it uses standard boat propellers
  • Motors: it also states that motors work fine in water, as long as they are dried after usage
  • Communications: it says XBee were used. I'm wondering that is the range of Xbee underwater

Awesome! Any updates on this? This is exactly what I want to do.
