RBD (robotic Beer Delivery)

July 13, 2010 by Mike Szczys 25 Comments

Those crazy programmers over at the Willow Garage are at it again. This time around they’ve created a robotic wench to deliver the beer. When thirst strikes you can fire up a web interface and drag a picture of your beer into a shopping basket. Once you submit your order the bot will raid the fridge and return with your frothy treat. It will even open the bottle for you but, as you can see after the break, this is where your beer becomes truly frothy.

So we’ve seen the PR2 playing pool, and now as a barmaid. Willow Garage just joined SparkFun on our list of places we wish we worked. Continue reading “RBD (robotic Beer Delivery)” →

DelFly2 And DelFly Micro

The video you see above is the on board footage of the DelFly2 autonomous ornithopoter robot. Weighing 16 grams, it carries a small camera and can provide a live feed. If you’re amazed at the tiny size and weight of the DelFly2, check out the DelFly micro, video after the break, that weighs 3 grams. Remember when we thought 17 grams was small for an ornithopter?

All processing for the DelFly2 is done at a base station and transmitted to the flying bot to keep the weight down. The team also had to create their own brushless motor that runs at 60% efficiency and weighs only 1.6 grams. The 130mAh battery can sustain 15 minutes of horizontal flight or 8 minutes of hovering.

Update: Acrobatic Quadcopters Team Up

July 12, 2010 by Mike Szczys 34 Comments

We usually envision small wheeled robots when we thing about swarm robotics but these cooperative quadcopters make us think again. This is an extension of the same project that produced those impressive aerial acrobatics. It may not be as flashy, but watching groups of the four-rotored flyers grab onto and lift loads is quite impressive. There is also a shot of one dropping a 2×4 and immediately compensating for the loss of weight. We’re not certain, but it looks like team lifting doesn’t require the 20 high-speed camera rig that the acrobatics did. We’ve embedded the demonstration video after the break.

CubeStormer; Quick Solutions From LEGO Parts

CubeStormer solves Rubik’s cubes and it does it quickly! Made entirely out of LEGO, a Mindstorm web camera is used to scan in the cube with four mechanical hands for manipulation. The device is capable of solving a random cube in less than 11 seconds. That’s quite a bit faster than the last Minstorm solver we saw, and the CuBear solver we are so fond of.

Try As You Might, Scooty Won’t Fall Over

July 10, 2010 by Mike Szczys 20 Comments

Scooty is a balancing robot based around a PIC32. The project is the first iteration in a long road toward a ridable version. The video after the break shows some incredible promise. Scooty is pitted against a large rubber ball. The two roll into each other but Scooty maintains balance thanks to that powerful processor, an inertial sensor, and a range finder.

Scooty versus a ball isn’t really fair to the ball. We’d like to see Scooty versus the ball balancing robot.

Autonomous Battery Exchange

July 9, 2010 by Mike Szczys 24 Comments

That may look like a Ferris wheel but it acts a battery replacement station for small robots. The marXbot heads to the battery station when it gets low on juice. Once in the cradle, arms on each side hold the bot in place while the low battery is sucked out and a fresh one from the 15-slot carousel is inserted. The robot doesn’t power down but relies on stored electricity from some large capacitors during the changeover. See it happen after the break.

A while ago we saw a robot that could plug itself into a wall outlet. That’s great because the robot doesn’t have to return to a charging station, but it still has to wait for its battery to top off. With a few strategically placed battery stations it’s easy to keep a robot up and running with almost no down time for a battery swap.

RobotsEverywhere

[Spiritplumber] has been sending us updates on a promising project he’s working on called RobotsEverywhere. We’re not completely sure if that name covers the project itself, or just the name of his group that is selling robots (and giving us schematics and source code). Either way, they have some really cool stuff. The really cool part about many of the bots is that they are using Android phones as their brains and they use the same system on land, air, and water. There’s tons of information sprinkled around the site and the Wiki, take a few minutes and look around.
