Whether they’re swooping in to deliver packages or spotting victims in disaster zones, swarms of flying robots could have a range of important applications in the future, a new study found. The robots can switch from driving to flying without colliding with each other and could offer benefits beyond the traditional flying-car concepts of sci-fi lore, the study said. Robots with similar versatility could fly over impediments on the ground or drive under overhead obstacles. But currently, robots that are good at one mode of transportation are usually bad at others, study lead author Brandon Araki, a roboticist at the Massachusetts Institute of Technology’s Computer Science and Artificial Intelligence Laboratory, and his colleagues said in their new study. The researchers previously developed a robot named the “flying monkey” that could run and fly, as well as grasp items. However, the researchers had to program the paths the flying monkey would take; in other words, it could not find safe routes by itself. Now, these scientists have developed flying cars that can both fly and drive through a simulated city-like setting that has parking spots, landing pads and no-fly zones. Moreover, these drones can move autonomously without colliding with each other, the researchers said. “Our vehicles can find their own safe paths,” Araki told Live Science. The researchers took eight four-rotor “quadcopter” drones and put two small motors with wheels on the bottom of each drone, to make them capable of driving. In simulations, the robots could fly for about 295 feet (90 meters) or drive for 826 feet (252 meters) before their batteries ran out. The roboticists developed algorithms that ensured the robots did not collide with one another. In tests in a miniature town made using everyday materials such as pieces of fabric for roads and cardboard boxes for buildings, all drones successfully navigated from a starting point to an ending point on collision-free paths. Adding the driving apparatus to each drone added weight and so slightly reduced battery life, decreasing the maximum distances the drones could fly by about 14 percent, the researchers said. Still, the scientists noted that driving remained more efficient than flying, offsetting the relatively small loss in efficiency in flying due to the added weight. “The most important implication of our research is that vehicles that combine flying and driving have the potential to be both much more efficient and much more useful than vehicles that can only drive or only fly,” Araki said. The scientists cautioned that fleets of automated flying taxis are likely not coming anytime soon. “Our current system of drones certainly isn’t robust enough to actually carry people right now,” Araki said. Still, these experiments with quadcopters help explore “various ideas related to flying cars,” he said. The scientists detailed their findings on June 1 at the Institute of Electrical and Electronics Engineers’ International Conference on Robotics and Automation in Singapore.

如果你是這位科學家，在技術尚未成熟到可以载人之前，為了確保機器人不會在真實街道上撞到路人或車輛，你會選擇在什麼樣的環境下進行實驗？請回想一下文中提到的「紙箱做的建築物」與「布料做的馬路」，這暗示了這個測試地點的本質是什麼？

同學，恭喜你準確地選出了正確答案！這顯示你不僅讀懂了細節，還具備了優秀的資訊歸納能力。
模擬環境與安全性驗證
這道題目的核心在於驗證科學家如何確保機器人的安全性。文章中提到，研究團隊開發了能自動避障的演算法，並在「模擬的城市環境（simulated city-like setting）」以及利用布料、紙箱搭建的「縮小版城鎮（miniature town）」中進行測試。選項 (D) 所提到的 artificial scenario（人工場景），精準地概括了這類並非真實自然環境、而是由研究者刻意打造的實驗場景。相較之下，選項 (B) 容易讓粗心的讀者誤以為是真實的小鎮，而 (C) 則只涵蓋了電腦模擬，漏掉了實體模型的測試。
