Both UAVs and ground robots have great potential for disaster response, but in general, these devices either fly in the air or walk on the ground.
The flying star, constructed by researchers at Ben Gurion University in Israel, can take both into account, using a very simple device.
The device is based on basic observations of the rotation of both the propeller and the wheel, and the researchers thought, why can’t a robot have both?
Of course, today’s lightweight drones, led by Zach rook, are hard to make with high-powered drones.
In this way, the robot can fly easily when needed, and then gently land on the ground, guiding the same power into the four wheels by tilting the rotor arm downward.
Some people will say that installing a few wheels on the bottom of the UAV can also make it roll and slide. But the robot improved the idea in a number of ways.
First of all, it is more efficient because the same motor drives both the rotor and the propeller, although the speed is much lower when sliding. But the arm also gives the robot a more flexible attitude, large wheelbase and high clearance, making it more able to operate in rugged terrain.
It can move at a speed of 2.5 meters per second, consumes relatively less energy, and can also cross obstacles, climb stairs or simply rise to a new position, which gives flying star considerable adaptability.
“We plan to develop larger and smaller versions of the robot to expand the different applications of the robot, as well as algorithms that help take advantage of the speed and transportation costs of these robots,” zaruk said in a press release
Obviously, this is only an initial prototype, and further development is needed to achieve an efficient version that can be applied to rescue teams, commercial activities and the military.
