🚨 Drones + Helicopters = Dangerous and Illegal 🚨 Yesterday around 3:40 p.m., a drone was filmed flying directly above a LifeFlight helicopter as it landed at Primary Children’s Hospital to transport a critically ill child. Because the drone was spotted, all air operations had to stop until the...

LEONARDO, also called LEO, was built by researchers at Caltech’s Center for Autonomous Systems and Technologies. Its full name means LEgs ONboARD drOne. The idea is simple but unusual: • Build a small biped robot • Give it drone-style thrust • Use the legs for ground contact • Use the propellers for balance and lift • Combine walking, hopping and flying in one system LEO is basically a hybrid between a walking robot and a flying drone. How it was built: • Two lightweight legs • Three actuated joints in each leg • Four propeller thrusters near the shoulders • A lightweight body • Leg motors for ground movement • Propellers for balance, lift and aerial control • Real-time control software that synchronizes the legs and propellers How it walks: • The legs move the robot forward • The feet touch the ground like a normal biped • The propellers constantly correct balance from above • The robot can stay upright even in unstable situations • The thrust reduces the risk of falling during difficult motions How it flies: • The legs stop being the main locomotion system • The four propellers generate lift • The robot behaves more like a drone • It can take off, fly over obstacles and land back on its legs What makes it different: • It does not walk like a normal humanoid • It does not fly like a normal drone • It blends both systems • The legs handle contact with the ground • The propellers act like fast stabilizers • The control system decides how much help comes from the legs and how much comes from thrust That is why LEO can: • Walk • Hop • Fly over obstacles • Ride a skateboard • Balance on a slackline The key idea is walking with aerial stabilization.

Americans are not ready to watch sons and daughters hunted by FPV drones. Some may not like this post, and that’s OK. Some may see this as being a “panican,” and that is also OK. My tolerance for American blood being spilled is very, very low. But this needs to be said: If you have paid any attention to the war in Ukraine, you will know how drone warfare has escalated. You will have an understanding of the sophistication of the Ukrainians and Russians in their pursuit of hunting and killing each other with human-guided robots strapped with explosives. We know Russia and Iran share military ties; hell, the most common form of long-range standoff munition used to target Ukrainian infrastructure is an Iranian-designed Shahed drone. Now, are the Iranians as sophisticated as the Russians? No. But will a ground action result in grainy videos of Americans being hit by FPV drones? Almost certainly. Could the deployment of ground forces to the Gulf be a feint? Sure, it could be, but this point extends beyond Iran. The U.S. needs to be ready to counter the drone menace. I won’t pretend to know the inner machinations of the Joint Chiefs, the White House, or President Trump, but with the destruction of an E-3 Sentry on the runway, it has become absolutely clear the U.S. armed forces have not scaled their ability to handle drones. I don’t know what the answer here is, but I haven’t seen this point brought up at the frequency it deserves. It needs to be said. We are not ready for footage of American soldiers and Marines cowering in their last moments, set to some upbeat pop song or some cleric screaming praises to Allah.
