A drone in the air and a robot on the ground

A few months ago, there was a mention of a drone floating in the water and flying in the air, and now Israeli experts have created a drone that flies in one direction while flying on the other. It's a quadcopter-type drone, but as soon as it touches the ground, its propeller arms curl up and form wheels. It's named F-Star (Flying Sproll-tuned Autonomous Robot). Experts at Ben-Goreo University in Israel have successfully converted a four-propeller quadcopter into a car. The four horizontal propellers provide the power to lift it and the drone can fly easily in any direction. But there are also four rotating wheels mounted with propeller arms mounted on brush-equipped motors that propel the propeller to the wheels, and the car runs at a speed of eight feet a second. A practical demonstration of this can also be seen in the video below. As soon as it is on the ground, its propellers rotate at 55 degrees and form the wheels. Thus in the case of any obstacle, it moves forward and overcomes the small obstacles. Once charged, it remains active for up to 20 minutes and can be used in search and rescue operations after an accident. It can easily carry 400 kilograms of goods, medicine or food in debris and tight spaces. Several versions of drone robots are working for different applications. Professor David Zarok, an associate professor at Ben-Gurion University, says that the next step can be improved by improving programs and algorithms and improving their performance
