A team of three researchers from Hong Kong City University has developed a small drone (Small maple drone based on maple pod) based on maple pods. Songnan Bai, Qingning he and Pakpong Chirarattananon, in a paper published in the journal Science Robotics, how they use maple pod as a stimulus to reduce drone flight time under 100 grams.
Maple trees are well known for their helicopter design. When they fall from a tree, they move like a rocket-propelled helicopter, causing them to expand their distance from the tree and blow it. In this new effort, researchers are trying to use its internal efficiency in the processing of maple fruit to increase the flight time of small drones. To do this (Small maple drone based on maple pod), they made a small drone that could move like a maple fruit to last longer. The resulting drone can fly almost twice as many as those with four rotor propellers.
Many drones have rotating rotors that provide lift. This new design has two small rotors and wingtips, so they rotate – the sweetness of the moving wings, increasing efficiency. The researchers also added electronics and batteries between drones. This assembly weighs less than 35 grams and rotates at about 200 revolutions per minute. Tests have shown that it can float in the air for up to 24 minutes. The researchers said that due to the internal strength, no microprocessor stability was required. They also say they get the aircraft to control the situation by changing the speed of the small rotors.
The researchers also tested the power of a small drone, including a camera. As the camera uses a moving drone, they adjust their center scale to match the speed of the moving drone, producing smaller but more useful videos. They have also demonstrated their ability to carry 21.5 grams for maps and tracking activities.
