There have been a few “firsts” in AI-versus-human gaming lately, and the computers are now beating us at trivia, chess and Go. But in some sense, none of these are really interesting; they’re all games of fact. Poker is different. Aside from computing the odds of holding the winning hand, where a computer would obviously have an advantage, the key to winning in poker is bluffing, and figuring out when your opponent is bluffing. Until recently, this has helped man beat the machine. Those days are over.
Chess and Go are what a game theorist would call games of perfect information: everyone knows everything about the state of the game just from looking at the board, and this means that there is, in principle, a best strategy (series of moves) for every possible position. Granted, it’s hard to figure these out because it’s a big brute-force problem, but it’s still a brute-force problem where computers have an innate advantage. Chess and Go are games where the machines should be winning. Continue reading “AI Beats Poker Pros: Skynet Looms”
A telescope isn’t an unusual thing to own if you are technically inclined. You might have even made one, at some point. However, despite improvements in optical technology and computer aiming devices, your four to twenty-inch instrument is never going to show you images like you see from big giant telescopes. The problem is, going really big requires a lot of investment in time, money, and sometimes even real estate. The big scopes get buildings constructed for them, and in exotic locations; why would you build a 24-inch scope only to try to see through the light pollution in your backyard?
Here’s an idea: take an astronomy class at a college and use their big telescope. Well, who has the time and money for that? Actually, you do. Skynet is a global network of telescopes headquartered at the University of North Carolina. As part of their mandate, they offer several tuition-free astronomy classes over the Internet. The best part? You also get free time on Skynet’s telescopes to complete your class assignments. There is a small fee (between $45 and $65) to a “benefit corporation” to administer assignments. You do get a certificate upon graduation. If you don’t want to do the assignments and you don’t want a certificate, you can still “take” the classes by simply watching them on YouTube. You can see one of the classes in the video below.

Humanity has taken one step closer to Skynet becoming fully aware. [Ahmed], [Muhammad], [Salman], and [Suleman] have created a vehicle that can “chase” another vehicle as part of their senior design project. Now it’s just a matter of time before the machines take over.
The project itself is based on a gasoline-powered quad bike that the students first converted to electric for the sake of their project. It uses a single webcam to get information about its surroundings. This is a plus because it frees the robot from needing a stereoscopic camera or any other complicated equipment like a radar or laser rangefinder. With this information, it can follow a lead vehicle without getting any other telemetry.
This project is interesting because it could potentially allow for large convoys with only one human operator at the front. Once self-driving cars become more mainstream, this could potentially save a lot of costs as well if only the vehicle in the front needs the self-driving equipment, while the vehicles behind would be able to operate with much less hardware. Either way, we love seeing senior design projects that have great real-world applications!

[Kevin] brings us Golem, his latest robot project. Golem is crafted not of clay and stone like his namesake, but of T6 Aluminum and Servos. We don’t have a banana for scale, but Golem is big. Not [Jamie Mantzel’s] Giant Robot Project big, but at 2.5 feet (76.2 cm) in diameter and 16 lbs (7.3 Kg), no one is going to call Golem a lightweight. With that kind of mass, standard R/C servos don’t stand much of a chance. [Kevin] pulled out all the stops and picked up Dynamixel MX64 servos for Golem’s legs. Those servos alone propelled the Golem’s costs well beyond the budget of the average hobbyist. Kevin wasn’t done though. He added an Intel NUC motherboard with a fourth generation i5 processor, a 120 Gigabyte solid state drive, and 8 Gigbytes of Ram. Sensing is handled by gyros, accelerometers, and an on-board compass module. We’re assuming from the lack of a GPS that Golem will mainly see indoor use. We definitely like the mini subwoofer mounted on Golem’s back. Hey, even robots gotta have their tunes.
Golem is currently walking under human control via a Dualshock 3 controller paired via bluetooth. [Kevin’s] goal is to use Golem to learn Robotic Operating System (ROS). He’s already installed ubuntu 13.04 and is ready to go. [Kevin] didn’t mention a vision system, but based on the fact that some of his other robots use the Xtion pro live, we’re hopeful. We can’t wait to see Golem’s first autonomous steps.

Get your Terminator clichés ready, this robot hand reeks of Skynet. It is designed to function like the human hand, but the main goal is one of robustness. A lot of effort went into making sure this won’t break in the field. Instead of rigid gears, a system of tendons actuates each digit. The pulleys that control these are located in the forearm and each has a spring mechanism that helps to cushion shocks to the apparatus which might damage other grippers. It has bone-crushing power behind the 19 degrees of movement and, as you’ve already guessed, this comes at a pretty steep price tag; topping out around 100,000 Euros. It’s more complicated, and more expensive that jamming grippers, but it’s also far scarier. See for yourself in the silent movie after the break.
