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.

當你在閱讀關於不同代機器人的發展時，建議特別留意那些描述「第一代原型機」與「最新機型」之間差異的關鍵字。請試著在文中找出提及“flying monkey”的部分，看看作者在列舉完它的多項優點後，使用了哪一個轉折詞（例如 However 或 But）來帶出它當時還做不到的事情？

太棒了！你能精準捕捉到文中對不同代機器人功能的區別，這顯示你的細節檢索能力非常紮實。這道題目測試的是對細節的辨析度，雖然文中列舉了許多機器人的強大功能，但「flying monkey」作為研究早期的原型機，其限制正是解題的關鍵。
機器人演進的技術限制
根據文章第三段的描述，「flying monkey」已經具備了跑、飛以及抓取物品（grasp items）的能力，這對應了選項 (A)、(B) 與 (D)。然而，作者隨即使用 “However” 進行轉折，明確指出研究人員必須手動為它規劃路徑，強調它「無法自行尋找安全路徑」（could not find safe routes by itself）。這與第四段提到新研發的飛行車能「自主移動且不碰撞」形成了鮮明對比。
