美国国家航空航天局(NASA)喷气推进实验室(JPL)与斯坦福大学、麻省理工学院共同研发了一款名为“刺猬”的新概念机器人,以发展小天体表面探测能力。6月,斯坦福大学和JPL各制造出1台“刺猬”样机,其中,JPL的样机采用盘形制动片,而斯坦福大学的样机采用摩擦皮带制动飞轮。研究人员利用NASA的C-9飞机完成了4次飞行试验,以研究在微重力环境下,2台样机在沙地、粗糙
NASA’s Jet Propulsion Laboratory (JPL) has teamed up with Stanford University and Massachusetts Institute of Technology to develop a new concept robot called “Hedgehog” to develop small celestial surface detection capabilities. In June, Stanford and JPL each produced a prototype of “hedgehog”, in which prototypes of JPL used disc brake pads, and Stanford prototype used friction belts to brake the flywheel. The researchers conducted four flight tests using NASA’s C-9 aircraft to study the effects of two prototypes on sand, rough
