在外星球上运行的探测器,比如“好奇”号火星探测器,几乎都是靠轮子前进,翻倒后就很难运行了。但小行星、彗星等小型天体重力非常微弱,地表又很粗糙,给这些探测器造成了“困扰”。如今,科学家正在研发一种叫“刺猬”的新型机器人,它在微重力小型天体上能翻滚、弹跳着行进并开展工作。“刺猬”的基本设计理念:在一个外部具有突起结构的立方体内安装能滚转和制动的调速轮,调速轮带动立方体前行;突起结构则一方面保护立方体免受地形崎岖之害,另一方面像脚一样起到支撑作用。 Detectors operating on alien planets, such as the “Curiosity” Mars probe, are almost always wheel-powered, making it difficult to operate after being overturned. However, small asteroids, comets and other small objects gravity is very weak, the surface is very rough, causing these detectors “troubled”. Now scientists are developing a new type of robot called “hedgehog” that rolls, bounces, and works on tiny, microscopic bodies. “Hedgehog ” The basic design concept: In a cubic structure with protruding structures installed can roll and brake flywheel, flywheel driven cube forward; protruding structure on the one hand to protect the cube from rugged terrain On the other hand, it plays a supporting role like a foot.
