除纤颤器无人机可挽救生命(图)
除纤颤器 无人机
2017/6/15
如果在医院外发生心搏停止,10人中仅有1人能生存下来。即便旁边有人能够进行胸部挤压提高患者生存几率,但仍需要用除纤颤器进行电击,使心脏重新跳动。每延缓1分钟实施心肺复苏术或是用除纤颤器,就会让患者的生存几率降低10%。除纤颤器可以发出语音指令,让每个人均可使用,因此很多公共场合都有除纤颤器。
日前,瑞典卡洛琳斯卡医学院的Jacob Hollenberg和同事想知道,如果用无人机携带除纤颤器到达紧...

仿生机器人家庭又添新成员 SCAMP”小型机器人能飞会落可爬墙
仿生机器人 SCAMP
2016/3/22
看过“阿特拉斯(Atlas)”视频的人都会对这个大型的两脚机器人印象深刻,但很多专家仍把重点放在功能性的小型机器人上,因为它们能到达大型机器人去不了的地方。最近,美国斯坦福大学仿生与灵巧操作实验室公布了他们正在开发的一种新机器人:既能在空中飞,又能在竖直墙壁上降落,然后还能顺着墙向上爬。
摁一下按钮,就可以遥控小鼠的行走路线,神奇吧!这其实是一种超薄的微创植入装置在起作用,通过它就可以用药物和光来控制脑细胞。
