Chilling in the pool is great, but what a drag to have to get out to grab a cold brew. [Alister] had his eye on a commercial drink float, but the company was out of business. But 3D printing, of course, comes to the rescue in this video, also embedded below.
The payload amounts to four bottles and some snacks. Brushless thrusters allow the bartender to steer the little robot around the pool to deliver libations.
A resin overcoat allows the 3D printed material to float. After the hull and thrusters are done, the rest is pretty simple: an RC receiver and some speed controllers round it out. For festivity’s sake, the boat sports an MP3 player, a water cannon, and a remote-control flagpole.
It looked like fun to drive around a pool. It might not be seaworthy enough for a trip to the ocean, but it would probably be workable on a quiet lake. We don’t know what the service life of the little device will be, but we wonder if you couldn’t sell these to resorts for delivering things to swimmers.
