The Creepy Collective Behavior of Boston Dynamics' New Robot Dog

"Robotics company Boston Dynamics has a new four–legged addition to its family: a 160–pound quadruped named Spot...

We know from Spot's reaction to that kick that he can dynamically correct his stability–behavior that's modeled after biological systems. From what Couzin can tell, the robots' collective movement is an organic outgrowth of that self–correction. When the two Spots collide at the 1:25 mark, they're both able to recover quickly from the nudge and continue on their route up the hill. 'But the collision does result in them tending to align with one another (since each pushes against the other),' Couzin wrote in an email. 'That can be an important factor: Simple collisions among individuals can result in collective motion.'

In Couzin's research on locusts, for example, the insects form plagues that move together by just barely avoiding collisions. 'Recently, avoidance has also been shown to allow the humble fruit fly to make effective collective decisions,' he wrote.

It doesn't look like Spot is programmed to work with his twin brothers and sisters–but that doesn't matter if their coordination emerges naturally from the physical rules that govern each individual robot. Clearly, bumping into each other isn't the safest or most efficient way to get your robot army to march in lock step, but it's a good start. And it's relatively easy to imagine several Spots working together in organized ways if the LIDAR sensors fitted on their 'heads' were programmed to create avoidance behaviors–like those locusts–rather than simply reacting to collisions.

Spot's life–like motions are uncanny, but when you add this emergent, collective behavior–which can sometimes be unpredictable–the possibilities get downright scary. Will Spot's group dynamics stop at the point of swarming like locusts? (Ominous.) Will they cluster into self–protecting balls like sardines? (Less so.) Or could they end up as smart and responsive as humans?

Couzin goes so far as to call this bump–and–grind between Spots One and Two a social interaction. 'No matter how primitive, there's no doubt that these interactions could enhance the decision–making capabilities of such robots when they must make their own, autonomous, decisions in an uncertain world,' he wrote. We'll just have to hope that decision–making involves not trampling us when a pack of Spots starts stampeding like wildebeest."

Theo Jansen: Strandbeests

"Dutch artist Theo Jansen has been working for 16 years to create sculptures that move on their own in eerily lifelike ways. Each generation of his "Strandbeests" is subject to the forces of evolution, with successful forms moving forward into new designs. Jansen's vision and long–term commitment to his wooden menagerie is as fascinating to observe as the beasts themselves.

His newest creatures walk without assistance on the beaches of Holland, powered by wind, captured by gossamer wings that flap and pump air into old lemonade bottles that in turn power the creatures' many plastic spindly legs. The walking sculptures look alive as they move, each leg articulating in such a way that the body is steady and level. They even incorporate primitive logic gates that are used to reverse the machine's direction if it senses dangerous water or loose sand where it might get stuck."
