Hopping, flying robot gets an all-terrain upgrade

e. Finally, the bottom of the foot pad is covered with short spikes that help it grip slippery surfaces. Compliant Footpads Enable Terrain-Adaptive Hopping in a Monopedal Robot These changes made a pretty significant difference. The new foot pad reduced performance variation across different terrains by 84%. In simple terms, the robot can now land much more consistently when moving between complex surfaces such as ic

n the air like a regular drone when there is no suitable place to land. By switching between flying and hopping, the robot could reach places that would only be accessible by airdrop otherwise. During the hop, the robot enters a free-fall state, and then, as it goes up, its four rotors engage very briefly. According to the creators, this allows the Hopcopter to cover quite long distances while using just one-tenth th

oped surfaces. To overcome these limitations, research partners at the University of Toronto came up with a new flexible foot pad that helps the robot land on different types of terrain. Its clever design has a few useful features to tackle all the possible challenges.

It also features three rubber bands that provide enough tension to bring the foot back into position after landing, helping the robot regain its balanc

The original prototype , announced two years ago, could successfully land on its single leg on flat surfaces like concrete or fine gravel and push off to get to the next spot. But once the terrain became less predictable, it struggled quite a bit: it would sink into sand, slip on ice, and often fall over when trying to land on sl

a quadcopter drone with a single spring-loaded leg that it can hop on, as you can guess from the robot’s name. Two versions of the Hopcopter City University of Hong Kong The idea was inspired by birds, which often hop from place to place instead of constantly flying, saving them a lot of energy. Similarly, the Hopcopter can hop from one spot to another without wasting its battery, but it can also continuously stay i

and can be stopped by something as simple as a set of stairs. Flying drones don’t care about ground conditions, but they can’t carry too much weight. There’s clearly room for something that combines the advantages of both. And this is exactly what the Hopcopter is designed to do. It was developed by researchers from City University of Hong Kong and The Hong Kong University of Science and Technology. Essentially, it’s

When it comes to designing modern robots, various researchers are all trying to solve pretty much the same problem: how to make robots that can reach places difficult for humans to access. They’ve come up with robots that can swim underwater , crawl through rubble , and land on tree branches like birds . But every existing type of robot has its own limitations. Wheeled and legged robots struggle with uneven terrain,
