Cheetah robot can run down even the fastest of us

It’s a blur, but you really don’t want to seen this thing coming for you anyway. It’s the latest look at what the folks at Boston Dynamics have been working on under a DARPA contract. They call it the Cheetah robot as it’s the fastest four-legged bot ever developed. The clip after the break shows it breaking the world record over 100 meters… for a human. This isn’t really legitimate since the run is done on a treadmill and the robot is tethered. But it’s still impressive scary.

The Cheetah is a relative of BigDog, another Boston Dynamics robot which we’ve seen several times in the past. BigDog specializes in lifting heavy loads and traversing rough terrain. We don’t think it will be too long before both traits can be “bred” into one device. A lot of times when we feature these robots there are comments about how they invoke images from The Terminator movies. For us this is more along [Michael Bay’s] vision of robots from the Transformers series. It certainly not small enough or fast enough to be seen as an early version of the Rat Thing.

Sand Flea literally leaps tall buildings in a single bound

The hidden abilities of this robot that is no larger than a dinner plate are quite impressive. It doesn’t let an obstacle like a building get in its way. The Sand Flea, like its namesake, posses a remarkable jumping ability. When it encounters a tall obstruction two levers incline the front of the robot and it launches itself up to thirty feet in the air. In the case of a one-story build this means it will end up on the roof, and it’ll do so much quicker and more reliably than any wall climber we’ve seen.

It’s being developed for the US Army by Boston Dynamics, and this isn’t the first time we’ve seen the concept. But the video after the break gives a much better look than the grainy twenty-second clip from last year. Of course they’re not giving up too many details so we have to guess a bit. We’d wager the launching mechanism is a solenoid, but at about eleven pounds you need a lot of juice to get that much of a jump. We suppose it’s also possible that there’s an explosive system like the butane combustion used in a framing nailer. The video summary mentions that there’s a stabilization system to keep the body oriented during flight. That’s got to be a gyroscope. Let us know what you think in the comments.

New BigDog video doesn’t fail to impress

Those following the evolution of quadrupedal assist robots will recognize the specimen seen above as a relative of BigDog. This is AlphaDog, one of the latest prototypes in Boston Dynamics’ Legged Squadron Support Systems program. It’s designed to carry 400 pounds of payload, which explains the disc weights seen on either side of the torso. Like its diminutive sibling, LittleDog, it’s able to take on all kinds of terrain. Here it’s being tested with boxes full of rocks.

The robot is capable of picking itself up and getting under way again without intervention. The first video after the break shows test footage where the robot starts nearly upside-down and has no trouble righting itself again. When we looked in on a biped version back in 2009 we also linked to the BigDog prototype which showed developers trying to tip it over mid stride. This version has the same balance resiliency.

Also embedded after the break is a video showing the evolution of the design over about seven years of development.

BigDog’s bipedal brother

Boston Dynamics is at it again. This time, they’ve created a creepy biped with a natural gait. It may look very similar to BigDog, because it really is almost the same system. Named PETMAN, this biped system is being designed to help test chemical protection suits. This bot can stress the suit by walking, running, and even crawling in a room filled with poison gas. Not only can PETMAN walk, run, and crawl, but it can also sweat and change its temperature.  That’s pretty cool. Like BigDog, the most impressive part is when they give it a shove and it recovers with a motion that seems almost organic.
