Boston Dynamic’s been keeping dog lovers happy throughout their steady development of BigDog, a robot with uncannily canine gait and maneuvers. Now, feline aficionados can finally rejoice as WildCat makes its way into the robot world.

However this is not the the first time that Boston Dynamics has taken a crack at cat-like bots — WildCat’s predecessor is the Cheetah bot which boasted a running speed of 45 km/hour. While this machine’s no slow poke, it can currently only run at about 26 km/hour but its truly biomimetic design should have it up to speed with real-world wild cats in the near future.

As part of US’ Defence Advanced Research Projects Agency’s (DARPA) Maximum Mobility and Manipulation (M3) program, robots like WildCat are being developed to increase the efficacy of military operations across a great range of missions.

And even though cats and dogs don’t normally get along in the real-world, humans may choose to have their robot counterparts working together. Machines like BigDog could be charged with the task of carrying heavy loads over long periods time, while ones like the WildCat might be used when there’s a need to maneuver with speed and agility.

But let’s not forget androids! If you were fascinated by Boston Dynamic’s PETMAN, it’s high time you check out its upgraded version Atlas. It may look a little scary in the video below but researchers are confident that bots like these might be able to help humans out in life-threatening situations.

The DRC won’t be all fun and games- its primary aim will be to foster the development machines fit to lend a hand to victims of natural or man-made diasters, executing risky tasks such as evacuation operations. DARPA notes that participants of the DRC should specifically focus on creating ground robots that are able to make use of human tools commonly applied in disaster relief situations.

Two of the four competition tracks are still open for registration. Check out the official website for more information HERE if you think your team may have what it takes!

Humans may not have the fastest or strongest bodies on earth but they are super multifunctional. Sure, we can’t jump as high as frogs, or swim as well as dolphins but we’re still able to achieve both forms of motion. The versatility of our physical ability has inspired us to create a world filled with tools and structures that would be impossible for many other animals to use – can you picture a cat using a door handle or a fish using stairs?

When industrial robots first came into the picture several decades ago, they were mainly used to accomplish very specific tasks and so their designs were purely functional. Today, there’s a big interest in developing robots for broader purposes including using them as research tools to further understand ourselves.

Some of today’s humanoid robots may seem a little bit creepy but sometimes it does make sense to give robots human-like bodies so they’re apt to operate amongst our human-centred designs. Many robots used for research need human bodies too, because researchers interested in studying human cognition know that while we need our brains to interact with our bodies, we also need our bodies in order to interact with the world.

So what does it really take to be a humanoid robot? Well, it should be able to move on two legs, use hands similarly to the way we do and perceive their own state and the state of the environment around them. They should also be able to communicate through modalities like speech or facial expression. Furthermore, they should be able to learn from and adapt to the environment around them.

This month, DARPA (the US’s Defense Advanced Research Projects Agency) announced a new robotics challenge: While they maintain that it’s not imperative that the robot take on a humanoid form, the robot must be compatible with human operators, environments and tools. Robots in the running will compete with each other in a sort of obstacle course that will pose 8 real-world disaster site challenges. Among the tasks are: climbing a ladder, driving a utility vehicle and removing debris blocking an entry way. Proposals are due by May 31st, 2012.

The video above features Boston dynamic’s PETMAN who may already be capable of performing some of those tasks. While it seems like a bot that could get some serious work done, there are other humanoids that are a little easier on the eyes!
