把弹簧单高跷、四旋翼和多伦多大学的工程学生组合在一起会得到什么？答案是眼前这个“单腿弹跳机器人”（monopedal hopping robot）——它使用一个带尖刺、可旋转的脚垫，由类似橡皮筋的弹性带张紧，从而在从软沙到硬冰的各种地形上保持直立。
这是一个有趣的概念。四个螺旋桨产生的推力为机器人移动提供能量，而它的弹跳动作完全来自弹簧加载的单腿“起落架”。早期版本只是在腿末端使用一个尖刺，但那会以一些令人发笑的方式失败——你可以在下方嵌入的视频中看到。给单腿装上一个真正有抓地力、可旋转并贴合地形的脚之后效果好了很多——现在这个机器人不仅能一跃跳过围栏，意外遇到的冰面也不会再让它滑走了。
这不是我们见过的第一个单腿机器人；有的只用腿，有的带翅膀，但这台奇特的四旋翼是我们见过的第一个敢于挑战加拿大冬天的。

What do you get when you combine a pogo stick, a quadcopter, and a University of Toronto engineering student? The answer is this "monopedal hopping robot" — which uses a spiked, rotating footpad tensioned by a rubber-band-like elastic band to keep its balance on terrain ranging from soft sand to hard ice.
It's an interesting concept. The thrust from the four propellers powers the robot's movement, while its hopping action comes entirely from the spring-loaded single leg "landing gear." Early versions used just a spike on the end of the leg, but that failed in some pretty hilarious ways — see the embedded video below. Giving the leg a proper grip-y, rotating, deformable foot made all the difference — now the robot can not only hop over fences, but it won't slip and slide when it encounters an unexpected patch of ice.
This isn't the first single-legged robot we've seen; some just use a leg, some have wings, but this odd quadcopter-hybrid is the first we've seen that's actually brave enough to take on a Canadian winter.
