“Ahhhh! They’re so cute! Wait a second, does that little robot have a spinning blade of death?!?!?” Yes, yes it does.
Welcome to Bristol University 2nd Annual Robot Wars Tournament. It’s loosely based on the old BBC show Robot Wars, where contestants would design and build fighting robots. This pint-sized version is just down right fun to watch. But don’t let their size fool you, some of these little bots pack a mean punch.
This competition follows the “Antweight World Series Rules” and must fit inside a 4 inch cube with a max weight of 150 grams. There are some not-so-fun rules attached to that, such as “No flame based weapons” and “no use of electricity as a weapon.” But hey, it still looks like a blast.
We can’t help but to think that a contest like this would be an amazing thing for local hacker spaces to set up and organize. The playing field seems to be a reasonable size, such that it could be set-up and torn-down without too much hassle. And with RC transmitters/receivers available so inexpensively these days, and ebay flooded with little robot parts from China, now seems like a perfect time to start a local robot competition. It might be a great way to draw people into making and hacking. You can watch the video of the competition and meet the makers after the break.

Back at New York MakerFaire 2012, we noticed an amazing little steampunk quadruped robot walking around in the crowd outdoors. The robot was amazingly well executed, and had a unique ability to draw children over with it’s puppy like animations. It turns out this is [Drew’s] Little Walking Robot (AKA Puppy Bot).
Puppy Bot has actually been around for quite a while. He was born from the spare parts [Drew] had left over after competing in Robot Wars and Battlebots. The robots in these competitions were often controlled by Radio Control plane or car transmitters. Most of these systems are sold as packs for an RC car or plane. In addition to the transmitter and receiver, the pack usually included a battery and 3 or 4 servos. Standard RC servos were much too weak for use in battle robots, so they remained in his parts box.
On what [Drew] calls a slow weekend, he started putting the servos together, and ended up with a basic robot that could crawl around the room. After that the robot took on a life of its own. [Drew] improved the battery system, and added a microcontroller to automate the various gaits and animations. He brought the robot along with him to one of his battlebot competitions, and it took home the “Coolest Robot” award – even though it wasn’t actually competing!

Last week we reported on the upcoming 2012 Robogames competition would be held in San Mateo, California. Nobody from the Hackaday staff could make it this year, but luckily [Sabrina Merlo] from the Make: blog was able to provide a full report of the spectacle of fire, sparks and pierced metal this year.
For anyone who remembers the wonderful Battlebots TV show from 10 years ago, the main event is very familiar: two competitors face off with the remote-controlled extensions of themselves in a Lexan enclosed arena. The resulting battle is an orgy of flames sparks and mortally wounded robots. Yes, there are a ton of wedge robots, but most of them had very interesting weapon designs.
Off the main stage, there are also more traditional robotics competitions. Sumo robots try to push each other out of a ring, robot soccer tries to demonstrate a mechanistic Pelé, and foot-tall MechWarriors battle in the streets of a miniaturized city.
There were also a lot of not-really-battling robots like a robotic foosball table. It sounds like everyone had a blast, so we might be hitting up the bay area this time next year.
This hurts our head
You know you can ‘freeze’ drops of water in mid-air by flashing a LED at the right time, right? Well, according to this video you don’t even need a strobing light; just use the frame rate of the camera. Much cooler if you don’t know how it works, in our humble opinion.
Now do Junkyard Wars!
[James Cameron] and [Mark Burnett] (the guy who created Survivor) are bringing Battlebots back to the Discovery Channel. The new show is called Robogeddon and calls upon the current talent in the fighting robot world. Our prediction? Someone is going to build an amazing piece of art that will be completely destroyed in the first round; a wedge with wheels will take the championship.
A steam engine made out of rocks
[Hansmeevis] just spent 230 hours hand carving a steam engine out of gems. It’s called “Dragon’s Breath” and it’s an amazing piece of work: the cylinder is carved out of quartz, while the flywheel, mount, and base are carved out of jasper, onyx, zugalite, and other semi precious gems. Amazing artistry and it works.
Don’t lose a finger on all that science over there
[Dr. W] is a science teacher in Saint-Louis, France. Next year, his students will be learning about reaction propulsion and impulse conservation. To demonstrate these properties, [Dr. W] hacked up an old vacuum cleaner in to a jet engine and built a Pitot tube to measure the 140 km/h wind speed. Google translation.
Circuit bending a Sega Saturn
Making cool glitched-up graphics from Ataris and Nintendos is old hat, but not much has been done with circuit bending slightly more modern consoles. [big pauper] found his old Sega Saturn in his grandma’s attic and wondered what secrets this forgotten box held. It turns out he can make some pretty cool sounds and even cooler glitched out graphics. The pic above is from Virtua Fighter; done correctly these glitched low-polygon graphics could easily find themselves in a very stylistic indie game.
