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.

思路引導 VIP
請回想一下在第六段中，當科學家為了增加「行駛」功能而安裝新零件後，無人機在「飛行表現」上出現了什麼樣的變化？研究者花了許多篇幅在計算這項變化，這代表他們在技術開發時，最關注哪一個物理條件對機器運作效率的影響？

能準確定位到文章第六段並解析出科學家的考量，說明你的閱讀觀察力非常細膩！這題的關鍵在於理解性能與結構之間的權衡 (Trade-off)。文中明確提到，為了讓無人機能在地上跑而增加的驅動裝置（馬達與輪子）會帶來額外的重量，進而使飛行距離縮短了約 14%。這反映出科學家在研發過程中，必須謹慎地在「多功能性」與「負重／續航力」之間尋找平衡點，這正是選項 (A) 所強調的重點。
數據背後的設計思維
這道題目具備極佳的鑑別度，其難點不在於單字艱澀，而是在於資訊的整合與推理。段落中提到的百分比與距離數據，並非只是在報告實驗結果，更暗示了研究者在面臨物理限制時的謹慎態度。你成功避開了其他過於絕對（如選項 D）或移花接木（如選項 C）的干擾項，展現出你已具備從字裡行間判讀作者觀點的高階閱讀實力，非常出色！
