Imagine a bustling small robot bee around the forest fields to help the real bees perform the important duties of their pollination for many decades in the future. Is a vision at the laboratory Harvard's Microorobotics Have been working for many years– obstacle? Until recently, the only thing that was landing at Harvard Robobe was expert.
Now, Harvard researchers have armed with their small Robobe with four long and elegant organs inspired by the crane. (Crane flies are scary insects. But not dangerous, which looks like flying spiders and people tend to specify that it is a giant mosquito). If there are details in the file study Published on Wednesday in the Journal of Science Robotics Soft Landing. Bring Robobees near the actual application, which today seems to be directly from sci -fi movies such as environmental inspection, surveillance, disaster, pollen, or even organism management.
“Previously, if we had to land, we would close a little vehicle above the ground and just put it and prayed that it would land and safely.” Christian Chan, a PhD student at the University of Harvard Engineering School and applied science. statement–
Led by Robert Wood, Professor of Engineering and Applied Science, Harvard Chan and his colleagues, looking for inspiration for new landing designs within the medical database of the university. In the end, they chose the Crane Fly's definition using Robobe with four -legged long legs for more soft landing. The update also includes improved controller. (Robot's brain) to slow down the landing methods of small robots. The combination of the “PLOP-DOWN” is gentle as described in the statement.
The previous version of Robobe tried to struggle to land, because the air vortices caused by flapping wings that create uncertainty close to the floor. It is a problem called “The ground effect” that the helicopter also has experience. Except that it is more challenging for Robobe because of the weight of 0.004 ounces (1/10th of grams) and its wings are only 1.2 inches (3 centimeters).
“The successful landing of any vehicle depends on the speed, while it is close to the surface before receiving the impact and energy quickly after being affected.” Nak-Seung Patrick Hyun, a former Harvard, and now an assistant professor at the PURDUE engineering school and the Purdue University “, even though there is a small man's genitals. But the ground effect is not appropriate when flying close to the surface and things will get worse after the bounce, while it bounces and bent. “Hyun is the leader of the Robobe's landing test on the solid surface and the leaf as well as real insects.
The legs of the cranes and controlled controls also protect the accessory. Piezoelectric The fragile of Robobee, which is equivalent to the muscles of a small robot. “The basic disadvantage of the accessory Piezoelectric for Microorobots is fragile and toughness. “The researchers explained in education. “The corresponding legs help to protect the account. Piezoelectric Which is delicate from the breakdown caused by collisions during the error landing. “
The team aims to make the Robobe sensor and the control of independence-what is called “Holy Grail three”, which will bring the practical application that is difficult to understand, which is more similar to the truth.
