Voice controlled home assistants are the wonder of our age, once you’ve made peace with the privacy concerns of sharing the intimacies of your life with a data centre owned by a massive corporation, anyway. They provide a taste of how the future was supposed to be in those optimistic predictions of decades past: Alexa and Siri can crack jokes, control your lights, answer questions, tell you the news, and so much more.
But for all their electronic conversational perfection, your electronic pals can’t satisfy your most fundamental needs and bring you a beer. This is something [luisengineering] has fixed, an he’s provided the appropriate answer to the question “Alexa: bring mir ein bier!“. The video which we’ve also put below the break is in German with YouTube’s automatic closed captions if you want them, but we think you’ll be able to get the point of it if not all his jokes without needing to learn to speak a bit of Deutsch.
As he develops his beer-delivery system we begin to appreciate that what might seem to be a relatively straightforward task is anything but. He takes an off-the-shelf robot and gives it a beer-bottle grabber and ice hopper, but the path from fridge to sofa still needs a little work. The eventual solution involves a lot of trial and error, and a black line on the floor for the ‘bot to follow. Finally, his electronic friend can bring him a beer!
We like [Luis]’s entertaining presentational style, and the use of props as microphone stands. We’ll be keeping an eye out for what he does next, and you should too. Meanwhile it may not surprise you that this is not the first beer-delivery ‘bot we’ve brought you.

[Josh] isn’t one to refuse a challenge, especially when robots are involved. The latest dare from friends and family? Build a beer robot that can bring beverages at everyone’s beck and call.
The build consists of two main parts: the refrigerated cooler and the butler part, which comes courtesy of a Roomba Discovery from a fellow roboticist. [Josh] is basing the design on double-walled and insulated restaurant coolers. He built the refrigerated beverage hold from two stainless steel trash cans, sized an inch or so apart in diameter, and filled the gap with expanding foam insulation. He then cut away several inches from the bottom of the liner can to make room for the cooling unit, reinstalled the drip tray, and made a [airflow-allowing platform] by drilling a bunch of holes in an antimicrobial plastic cutting board.
At first, he tried a Peltier unit from an electric Igloo cooler, but that doesn’t work as well as [Josh] hoped, so he’s redesigning the can to use a mini fridge compressor. This meant making custom evaporator and condenser coils from copper tubing to match the compressor’s load spec. Go through [Josh]’s build logs over on IO and you’ll get a free mini-course on expanding foam and refrigeration.
[Josh] is currently working on some different butler modes for this robot. These run the gamut from simply sitting nearby with cold beverages and opening with the wave of a hand to doing voice-triggered beverage butler-ing at everyone’s beck and call. We applaud his efforts thus far and will be following this one with great
thirst interest to see how he handles navigation and voice control.
[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.

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!
