RC Beer Crate Handles Rough Terrain like a Pro

[Niklas Roy] is at it again. Summer time means beer time and what better way for him to distribute beer at outdoor parties than a with an amazingly agile remote controlled beer crate capable of handling rough backyard terrain. With the controller firmly in hand he could even institute a leave-an-empty, take-a-beer policy to speed clean-ups.

We’ve seen awesome beer dispensing robots with all the bells and whistles in the past, from ones that are moving coolers, decapping the beer before handing it off, to BREWSTER the modified roomba who’ll fetch you a beer from a mini-fridge. [Niklas]’ RC beer crate sits at the simplicity end of the spectrum, reminding us of the no nonsense Star Wars mouse droid that wandered the Death Star’s corridors. The beer crate sits on a low wooden platform with a lip added to it to keep the crate from sliding off.  Under the platform are your basics: 2-channel RC receiver from a cheap toy car, H-bridges, two windscreen wiper motors and wheels, a LiPo battery, an on/off switch and two casters. For an arcade feel, the RC controller is a modified Competition Pro offering retro joystick steering.

As you can see from the video after the break (with a party-appropriate Metal soundtrack) it’s incredibly stable, moving rapidly over patio stones, from patios stones to dirt and lawn and even up messy inclines. This one’s sure to add excitement to many parties, while keeping party goers well served.

Quadcopter Beer Delivery System

One of the major design challenges when it comes to building an efficient quadcopter is weight. The idea here is that the more you can trim down the weight of the frame, motors, and circuitry, the longer the batteries will last. Or, in [dalbyman]’s case, the more beer it can carry.

[Dalbyman]’s housemate built the actual quadcopter, but then [dalbyman] got a little inebriated and decided that, while the quadcopter was exciting on its own, it would be even better with this modification. The actual device is a modified Pringles can with two servo motors on the bottom with arms that hold the beer. A parachute is attached to the beverage can and the assembly is loaded in. With a simple press of a button, the servos turn the arms and the beer falls out of the tube. Hopefully the parachute deploys and gently (and accurately) floats the beer to the thirsty person on the ground!

This project is a simple step that goes a long way towards a beer delivery system even Amazon could be proud of, and also shows off the capabilities of quadcopters in general. Perhaps the next step could be to automate the beer delivery system!
