NES robot mash-up competes in robo boxing tournament

In a move that brings back memories of the R.O.B. (Robotic Operating Buddy) that was available for the original Nintendo Entertainment System, Japanese hobbyist Izumi Ninagawa has simplified the controls of a modern fighting robot to work with a Famicom (8-bit NES) game pad – which has one of the most basic button configurations around. The NES-styled robot even competed in a robot boxing tournament earlier this yearNinagawa's XEMNES robot is based on a lightweight kit sold by De Agostini called ROBO-XERO, which weighs less than one kilogram (2.2 pounds) and is powered by 24 Futaba servo motors. By attaching a Bluetooth dongle to the robot with a special micro controller, Ninagawa was able to take advantage of various wireless controllers, including the Nintendo Wii remote. The remote was then hidden inside the shell of a Famicom, and attached to the Famicom controller using an adapter to complete the set-up.Despite the NES pad's limited number of buttons, various combinations of button presses allow Ninagawa to get the robot to stand up, walk, squat, punch, and strike (with a NES paddle tonfa). According to Ninagawa, if you've played video games before the controls feel natural and intuitive. In fact, most hobby robots are controlled with game controllers (especially the PlayStation pad, which allows for many possible actions given its button configuration).

This February, the robot was successfully entered into ROBO-ONE Light, the welterweight class of a popular hobby robot boxing tournament. The tournament gathers hobbyists from across Japan to show off their creations and fight one-on-one for cash prizes and street cred. The rules are relatively simple: knock your opponent down three times (or win by knock out if they can't get up before the count). You can see a breakdown of XEMNES's modifications and watch it duke it out with an unmodified ROBO-XERO kit in the following video.

Nerf Vulcan Sentry Gun tracks targets and avoids friendly fire

Anyone who plays video games will know that few things protect an area like a well-placed sentry gun. In the real world, though, even a person's bedroom or office could use a little protection sometimes, which is why one designer has built the Nerf Vulcan Sentry Gun. Using a custom program and some servos, the sentry can automatically locate targets and unleash a stream of foam darts at over seven times the usual speed, while keeping its owner out of the crosshairs. Britt Liv Ulrike Michelsen, a chemical and biological engineering student from Germany, designed and constructed the sentry using mostly basic electronics and some plywood. This isn't the first time she's modified a Nerf gun, but building this robotic turret is arguably her most ambitious project to date. Luckily, the Nerf Vulcan already operates using an electric motor, so controlling the actual firing mechanism through a computer was just a matter of connecting it directly to an Arduino Uno and a laptop. ...

Students crash rockets to develop new asteroid sample collection technique

In what at first glance seems like a terrible sense of direction, in March students from the University of Washington fired rockets from kites and balloons at an altitude of 3,000 ft (914 m) straight into the ground at Black Rock, Nevada: a dry lake bed in the desert 100 mi (160 km) north of Reno. This may seem like the ultimate in larking about, but it's actually a serious effort to develop new ways of collecting samples from asteroids. The test was part of the “Sample Return Systems for Extreme Environments” project. The idea is to find cheaper, more efficient ways of collecting samples from asteroids and hazardous areas on Earth, such as volcanoes and nuclear disaster zones, by using penetrators instead of soft landers or ground crews to hammer out sample cores. According to the team, this would result in lower cost than soft landing techniques by reducing the velocity and vehicle mass needed to gather the sample, minimizing damage on impact, as well as being mechanically s...

Review: i-H2GO hydrogen-powered remote-control car

At the end of last month, Horizon Fuel Cell Technologies began shipments of its latest hydrogen fuel cell-powered remote-control toy car, the i-H2GO . Like its predecessor, the H2GO , it runs on hydrogen obtained from user-supplied water. The main thing that's new about the i-H2GO, however, is the fact that it is now controlled using a free app on the user's existing smartphone. I got my hands on an early production model, mainly just so that I could truthfully say "I've driven a fuel cell car." Like the H2GO, the new car comes with an included Refueling Station. The user pours purified water into that device, and it proceeds to electrolyze the H2O, separating it into H and O – hydrogen and oxygen. A plunger on the station rises as hydrogen fills its temporary holding compartment. The user then connects the car to the station using a built-in hose, and manually pumps the hydrogen from the station into the car. The car's fuel cell subsequently combines...
