Meet Goat, the shapeshifting robot designed to move across almost any terrain by changing its form in real time
0:11
Developed by researchers at EPFL, Goat stands for good over all terrain
0:16
and it's built to handle obstacles in a way that's totally different from most robots
0:20
Instead of relying on tons of sensors and complex programming, goat adapts as it moves
0:25
Kind of like how a mountain goat climbs steep cliffs or an armadillo rolls into a ball for particular
0:29
But Goat takes it a step further. It can switch between different movement styles on the fly
0:35
It has two main modes, a flat rover mode where it drives like a tiny off-road vehicle
0:40
and a spherical mode where it rolls to save energy. Rolling is perfect for going downhill or moving over rough terrain
0:46
While the rover mode gives it more control on flat ground, and it's not just limited to land
0:51
It can even float and paddle through water. The secret behind this? A very simple but smart design
0:56
Goat's body is made of flexible fiberglass rods, and it more than rods and it morphs using cables kind of like how tendons in our bodies work Two cables tighten the structure allowing it to shift between shapes Its battery computer and sensors are securely stored in the center keeping them protected while it rolls like a ball Goat doesn use cameras either Unlike most autonomous robots that need high
1:16
vision systems to navigate, Goat just follows the easiest path using a basic navigation system
1:22
With only satellite positioning and an orientation sensor, it moves with the environment instead
1:26
of trying to overpower it. That means fewer expensive sensors, less processing power, and a more
1:32
efficient way to explore tough landscapes. The researchers behind Goat took inspiration from
1:36
animals like spiders, cockroaches, and even octopuses, creating a robot that's both adaptable
1:42
and energy efficient. Because of its simple but effective design, it has a ton of potential
1:46
applications, from exploring disaster zones and monitoring the environment, to even one day
1:51
traveling to other planets. Right now, Goat is still in its early stages, but scientists are
1:56
already working on ways to improve it, from better algorithms to different sizes for different tasks
2:02
And who knows? The future of robotics might not be about building bigger, stronger machines, but smarter, more flexible ones
