Combat robots have been a thing for a while, but we don’t normally get a close look at the end results of the sort of damage they can both take and deal out. [Raymond Ma] spent time helping out with season four of BattleBots and wrote about the experience, as well as showed several pictures of the kind of damage 250-pound robots can inflict upon each other. We’ve embedded a few of them here, but we encourage you to read [Raymond]’s writeup and see the rest for yourself.
The filming for a season of BattleBots is done in a relatively short amount of time, which means the pacing and repair work tends to be more fast and furious than slow and thoughtful. [Raymond] says that it isn’t uncommon for bots, near the end of filming, to be held together with last-minute welds, wrong-sized parts, and sets of firmly-crossed fingers. This isn’t because the bots themselves are poorly designed or made; it’s because they can get absolutely wrecked by the forces at play.
Combat robotics has been around for as long as people have been able to give a power tool some wheels and point it towards an opponent. Flying bots are even getting into the scene nowadays, with DroneClash leveraging the explosive growth of the drone industry to take the action into the air.
If you’re too young to remember Battlebots on the television, there are two things that you should know. First is that there are plenty of highlights of this epic robot battle royale on YouTube, and the second is that now there’s an even better version with drones instead of robots merely confined to land. It’s called DroneClash 2019, and it looks like it was amazing.
Not only were the robots set up in a box and asked to battle each other, they first had to navigate down a corridor with anti-drone measures. The drones have to make it through and into a battle royale in the final room. If this wasn’t good enough, the event was opened by a prince of the Netherlands and is put on by a university.
This is an annual event to push the state of the art in drone and anti-drone tech, but we’d be happy to see it optioned for a TV show. If it doesn’t, you might be satisfied with a giant human-driven robot competition from a while back, or maybe just head down the rabbit hole of old Battlebots clips.
There was an unbelievable amount of stuff on display at the 2018 World Maker Faire in New York. Seriously, an unreal amount of fantastically cool creations from all corners of the hacker and maker world: from purely artistic creations to the sort of cutting edge hardware that won’t even be on the rest of the world’s radar for a year or so, and everything in between. If you’ve got a creative bone in your body, this is the place for you.
But if there was one type of creation that stood out amongst all others, a general “theme” of Maker Faire if you will, it was robotics. Little robots, big robots, flying robots, battling robots, even musical robots. Robots to delight children of all ages, and robots to stalk the darkest corners of their nightmares. There were robots for all occasions. Probably not overly surprising for an event that has a big red robot as its mascot, but still.
There were far too many robots to cover them all, but the following is a collection of a few of the more interesting robotic creations we saw on display at the event. If you’re the creator of one of the robots we didn’t get a chance to get up close and personal with in our whirlwind tour through the Flushing Meadows Corona Park, we only ask that you please don’t send it here to exact your revenge. We’re very sorry. (Just kidding, if you have a robot to show off drop a link in the comments!)
The world is full of educational robots for STEAM education, but we haven’t seen one as small or as cute as the Skoobot, an entry in this year’s Hackaday Prize. It’s barely bigger than an inch cubed, but it’s still packed with motors, a battery, sensors, and a microcontroller powerful enough to become a pocket-sized sumo robot.
The hardware inside each Skoobot is small, but powerful. The main microcontroller is a Nordic nRF52832, giving this robot an ARM Cortex-M4F brain and Bluetooth. The sensors include a VL6180X time of flight sensor that has a range of about 100mm. Skoobot also includes a light sensor for all your robotic photovoring needs. Other than that, the Skoobot is just about what you would expect, with a serial port, a buzzer, and some tiny wheels mounted in a plastic frame.
The idea behind the Skoobot is to bring robotics to the classroom, introducing kids to fighting/sumo robots, while still being small, cheap, and cute. To that end, the Skoobot is completely controllable via Bluetooth so anyone with a phone, a Pi, or any other hardware can make this robot move, turn, chase after light, or sync multiple Skoobots together for a choreographed dance.
Where do you go if you want crazy old electronic crap? If you’re thinking a ham swap meet is the best place, think again. [Fran] got the opportunity to clean out the storage closet for the physics department at the University of Pennsylvania. Oh, man is there some cool stuff here. This room was filled to the brim with old databooks and development boards, and a sample kit for the unobtanium Nimo tube.
The Gigatron is a Hackaday Prize entry to build a multi-Megahertz computer with a color display out of TTL logic. Now, all this work is finally paying off. [Marcel] has turned the Gigatron into a kit. Save for the memories, this computer is pretty much entirely 74-series logic implemented on a gigantic board. Someone is writing a chess program for it. It’s huge, awesome, and the kits should cost under $200.
The Atari Lynx went down in history as the first portable console with a color LCD. There was a problem with the Lynx; the display was absolutely terrible. [RetroManCave] found someone selling an LCD upgrade kit for the Lynx, and the results are extremely impressive. The colors aren’t washed out, and since the backlight isn’t a fluorescent light bulb (yes, really), this Lynx should get a bit more run time for each set of batteries.
Like dead tree carcasses? You need to butcher some dead tree carcasses. The best way to do this is on a proper workbench, and [Paul Sellers] is working on a video series on how to make a workbench. He’s up to episode 3, where the legs are mortised. This is all done with hand tools, and the videos are far more interesting than you would think.
If you need some very small, very blinky wearables, here’s an option. This build is literally three parts — an LED matrix, an ATtiny2313, and a coin cell battery. Seems like this could be an entry for the Coin Cell Challenge we have going on right now.
Two years ago we wrote about a giant robot battle between the USA and Japan. After two years in the making, MegaBots (team USA) and Suidobashi (team Japan) were finally ready for the first giant robot fight. If you are into battle bots, you probably did not miss the fight that happened around 7:00 pm PST. If you missed it, you can watch the whole thing here.
There were two duels. First it was Iron Glory (MkII) vs. Kuratas, and after that it was Eagle Prime (MkIII) vs. Kuratas.
The battle’s are done and the results are in — [AltaPowderDog]’s, aka [Carter Hurd], cardboard and foam armor, lightweight Krave robot beat its metal cousins in 2016 and fared well in 2017. How did a cardboard Krave cereal box and foam board robot do that you ask? The cardboard and foam outer structure was sliced, smashed and generally eaten while the delicate electronics, motors and wheels remained buried safely inside.
We covered the making of his 2016 version but didn’t follow-up with how it fared in that year’s Illinois Bot Brawl competition. As you can see in the exciting first video below, despite suffering repeated severe damage to its armor, it won first place in the 1 lb Antweight category!

For 2017 he made another one but managed to halve the weight — and so he made two of them! By starting them both within a twelve-inch by twelve-inch area, they were allowed to fight as a team. How did he make it lighter? Partly it was done by doing away with the ability to lift the metal lip in front, the wheels were reduced from four to two, and a smaller servo was used for opening and closing the mouth. The full build video is shown below along with a video of the 2017 battles wherein he won seventh place.
