A drone slicing by means of the sky is one thing you don’t see on a regular basis, a lot much less one weaving previous obstacles with finesse, solely to—bam!—twist its physique mid-flight, tuck in its legs, and morph right into a wheeled rover, rumbling easily over rocky floor. That’s ATMO, a jaw-dropping robotic from Caltech’s Middle for Autonomous Programs and Applied sciences (CAST), dubbed the Aerially Reworking Morphobot, redefining robotics by mixing aerial grace with rugged terrestrial grit.
Caltech’s staff, spearheaded by grad pupil Ioannis Mandralis, took a web page from nature’s playbook to beginning ATMO, impressed by birds that tweak their our bodies midair to decelerate or slip by means of tight spots, effortlessly switching from hovering to perching. “We designed and constructed a brand new robotic system that’s impressed by nature—by the way in which animals can use their our bodies in several methods to attain various kinds of locomotion,” Mandralis explains. This biomimicry drives ATMO’s potential to remodel midair, a feat that units it aside from different hybrid robots that sometimes must land earlier than switching modes.

At its core, ATMO’s a quadrotor drone with 4 propellers, however right here’s the kicker: its legs reshape on the fly. These legs, fitted with wheels, let it contact down and roll like a mini Mars rover, tackling terrain that’d strand most drones, with an onboard pc calling the photographs in seconds to choose the most effective mode for the bottom. Hit a tough patch? ATMO simply pops again into the air, flipping to flight mode and not using a hiccup.
In a catastrophe zone, this factor may zip over crumbled buildings, then roll by means of rubble to drop provides or hunt for survivors, a game-changer for rescue ops. For planetary exploration, ATMO can soar over Martian craters earlier than rolling throughout rocky plains, gathering knowledge the place conventional rovers or drones may fail. “Being able to remodel within the air unlocks lots of prospects for improved autonomy and robustness,” Mandralis says, hinting at ATMO’s potential to redefine robotic missions.
Crafting ATMO was no stroll within the park—midair shape-shifting calls for featherlight but robust engineering, plus software program that thinks quicker than a reflex. The crew, together with design engineer Reza Nemovi and Caltech prof Richard M. Murray, poured years into perfecting it, with their Communications Engineering paper breaking down how ATMO’s tiny motor actuators pull off its morphing magic.
ATMO’s the most recent in Caltech’s robotics scorching streak, constructing on the Multi-Modal Mobility Morphobot (M4), which may fly, stroll, and roll however couldn’t swap modes midair, and LEONARDO, a two-legged bot with propeller arms that skateboarded and tightrope-walked. ATMO pushes the envelope, making these seamless transitions sensible sufficient to really hit the actual world.
