Caltech’s bird-inspired robot uses thrusters to help stay on its feet

[Coming Soon] Caltech's Leonardo Robot (Flying Bipedal Robot)

With their delicate and gangly legs, birds aren’t necessarily the first animal you’d think of when designing a new robot that looks to nature to create effective walking abilities. But birds, with their ability to flap their wings, possess a method of stabilizing themselves that’s not available to many other animals. That’s what researchers from the California Institute of Technology seized upon when developing their new Leonardo robot.

An acronym (well, kind of) derived from “LEg ON Aerial Robotic DrOne,” the lightweight, crane-like Leonardo boasts a pair of thrusters on its body. Although it is perfectly capable of walking on its two legs without help, the thrusters allow it to carry out a kind of locomotion that’s midway between hovering and walking. Should the robot lose its balance, these thrusters help provide the necessary force for it to stay on its feet. They are also capable of making the robot fly short distances while entirely supporting its weight.

While a few robots have explored methods of getting back to their feet once they fall, this is actually a pretty smart approach that could make it easier for robots like Leonardo to be deployed in settings with rougher, more uneven terrains. It’s something that will be particularly useful when it comes to robots used, for instance, in rescue situations, where there’s no guarantee that the surface will be as perfectly flat as it is in a lab setting.

It’s not just rescue operations where Leonardo could prove its value. Caltech has been working with NASA on technologies for future Mars exploration. Leonardo could turn out to be perfect for the job of bipedal exploration robot by being able to float/walk over the red planet’s surface in a way that would challenge many ground-based robots.

Since it’s still currently only usable when tethered, there is clearly a lot more work to be done on this project. However, this is definitely an innovative approach to bipedal robots that takes an unlikely inspiration and turns it into something potentially transformative.

We’re excited to see what Caltech is able to come up with as the next step in the Leonardo project. Hey, a better acronym would be a fine start!

Scaling vertical walls and even hanging from the ceiling: Insects have an incredible ability to maneuver in ways impossible for larger mammals. Now, scientists from the University of Berkeley are taking inspiration from this class of animals to design a fast, agile, tiny robot.

Robot vacuum with triple lidar system has eyes to help it avoid poop
robot vacuum uses triple lidar avoid dog poop 360 s10

Robot vacuums are supposed to help clean your home, not dirty it up in a catastrophic way. That's why tales of robot vacuums running over poop and smearing it across the floor create so much schadenfreude -- while it's hilarious to hear about, it's not so much fun when it happens to you. The 360 Smart Life Robot Vacuum Cleaner has eyes to help it detect such messes and obstacles before there are any mishaps.

How, exactly? Does it have a built-in poop sensor? Not really -- but it does use a triple light detection and ranging (lidar) system to better identify slim objects on the ground in front of it, including pet-induced Tootsie Rolls. Most modern robot vacuums use only a single sensor, which gives them something of a "2D" view. While they are aware of potential objects in their path, the devices do not receive enough information to judge its size.

boston dynamics robots end 2020 with amazing dance show dancing

Robot specialist Boston Dynamics has made a name for itself in recent years, building incredibly agile machines that can run, leap, somersault, and even pull nifty dance moves designed to give the best human hip-shakers a run for their money.

Its rare for Boston Dynamics to open its doors to anyone other than employees, but after “years” of asking, CBS’s 60 Minutes team was recently granted special access to the company’s Massachusetts workshop.
