Yamaha Designs a Robot That Can Ride Motorcycles

We’ve built robots that can swim, cook, and even comfort you on your death bed. Now, Yamaha has unveiled a new robot designed to do what no humanoid robot has done before: cruise on a motorcycle.

Motobot is an autonomous robot built to ride motorcycles similar to how a human rider would, right down to turning the throttle. The initial model that debuted at this week's Tokyo Motor Show still has some catching up to do before it reaches human capabilities, though. For now, it moves along at slow speeds and needs “training wheel” wings to protect it from toppling over. 

Yamaha’s long-term goal is to get Motobot zooming at 120mph on a racetrack, challenging the speeds of experienced human racers. But this robot isn’t built for competing in futuristic racing events. Instead, Motobot is designed as a tool to test safety and support systems for Yamaha’s human riders.

Cool idea, though Yamaha ruins any chance Motobot had at being charming with their promo video. Unsettling quotes include “I was created to surpass you” and “Perhaps if I learn everything about you I will be able to catch up." If Motobot ends up leading the robot uprising, at least he'll do it in style.

Popcorn Might Be the Cheap, Biodegradable Robot Power Source of the Future

If you've ever put a flat bag of kernels into the microwave and pulled out a full bag of fluffy popcorn two minutes later, you've witnessed a fascinating bit of food chemistry at work. Now, IEEE Spectrum reports that scientists are looking into applying the unique properties of popcorn to robotics.

For their study, presented at this year's IEEE International Conference on Robotics and Automation, Cornell scientists stuffed the movable parts of a robot (a.k.a. the actuators) with unpopped kernels of corn. Usually actuators are powered by air, hydraulics, or electric currents, but as the researchers found, popcorn works as a cheap single-use alternative.

When heat is applied to popcorn kernels, the water trapped inside them turns to steam, creating enough pressure to peel back the tough exterior and release the starchy endosperm. A sudden drop in pressure causes the endosperm to quickly expand, while the cool outside air solidifies it.

The results can be dramatic: When popping extra small white kernels, the cheapest popcorn tested, researchers saw them expand to 15.7 times their original size. Inside a soft robot, this amounts to building interior pressure that moves the actuator one way or another.

A similar effect can be achieved using air, and unlike popcorn, air can be pumped more than once. But popcorn does offer some big advantages: Using popcorn and heat is cheaper than building air pumps, plus popcorn is biodegradable. For that reason, the researchers present it as an option for robots that are designed to be used once and decompose in the environments they're left in.

You can get an idea of how a popcorn-powered robot works in the video below.

Disney Parks May Soon Have Robotic Stunt People

Animatronics are a staple of any Disney park, but as the company introduces more characters into the fold—like heroes from Star Wars, Marvel, and Avatar—the bar is being raised on audience expectations. On the screen, these characters defy gravity and pull off death-defying stunts, yet at the Disney parks, they’re still relying on fairly static animatronic models for their live shows and attractions. As Tech Crunch details, though, the gap between what the heroes do on film and in the park may be closing.

This development is all thanks to Disney’s R&D department, where Imagineers are working on next generation animatronics that can pull off aerial stunts like you’d see in any of the studio’s blockbuster films. The project is called Stuntronics, and its goal is to create animatronic stunt "heroes" that can replace a more static model in the middle of a Disney park show when the scene requires some high-energy action to take place. It's similar to the flesh and blood or CGI stunt people that movies have been using for decades.

In a video demonstrating their progress, a robot model is shown leaping from a cable to do backflips, double backflips, and other heroic landings. It’s something straight out of a Spider-Man movie and is years ahead of any animatronic character currently at the park.

Tony Dohi, principal R&D Imagineer at Disney, told Tech Crunch that the idea for this type of animatronic came about because they realized there was a “disconnect” between the exhibits at the park and what people see on film, so swapping in advanced animatronics for complex action scenes would go a long way toward making Disney’s parks feel more authentic to their properties. The Na’vi Shaman from the Avatar exhibit shows that Disney can get their animatronics to emote; this next step will put them into action.

According to Tech Crunch, right now the stunt robots are realized with the help of an “on-board accelerometer and gyroscope arrays supported by laser range finding.” They are autonomous and self-correct their aerial stunts to hit their marks. Though the model used in the video is just a generic mockup, it’s not hard to see how the Imagineers at Disney can easily turn it into any number of heroes from Marvel or Star Wars.

Stuntronics is just one of the advancements happening with robotics at Disney. Tech Crunch also detailed the Vyloo, which are a trio of autonomous bird-like robots in the park that react to guest movements. They can be seen in the Collector's Fortress in the Guardians of the Galaxy – Mission: BREAKOUT! attraction at Disneyland in California.

The Stuntronics project is still in the R&D phase with no practical application in place just yet. But if this technology does progress the way the Imagineers are hoping, the blockbuster action of Star Wars, Marvel, and The Incredibles won’t just be exclusive to the movies anymore.
