1016章：感应贴片的局限性
最新网址：m.ltxsdz.com
杯子里有泡好不久的茶，仿生右手也稳稳地抓住了杯子。杯子放下，他的信心受到巨大鼓舞，把手伸向了一个很常见的空调旋钮开关。
没想到，感应贴片的局限性一幕出现了。
他明明想伸出大拇指、拇指和食指，去捏住那个旋钮。可转化为实际动作，确是抓取水杯的动作，仿生右手张开握住了旋钮。
苏宇航又尝试了一次，然后呆呆站在原地。
“这个动作是可以做到的。”姜舒雅绕到他身后，轻声说道：“以奥托博克的产品来说，它能做到三十多种不同的手指联动动作，对应的是七种主要手势功能。”
“比如扭动旋钮之前，用户先要用左手轻轻点一下小拇指和无名指。这两根手指，在随后的运动过程中，就不会参与进去。”
“你现在带的这个，可能没增加这项功能。”
苏宇航不知在想什么，有些分心。
叶青看着屏幕上的数据，在皱眉思考。
由热神经元组成的仿生手，当然比奥托博克这种机械运动的先进十倍。可是采用了同样的感应贴片技术，仿生手无论多先进，在患者身上，也只能做出和后者一样的动作。
这当然不是叶青想要的。
这双仿生手内部，集成了各种从守望者X型机器人那里，移植过来的微型传感器技术。
奥托博克公司一直喜欢吹自己的三维力传感器，可在巨兽工业的这双仿生手上，六维力传感器也只是很低级的配置。
问题是这些配置，无法帮助用户做出他们想要的姿势。
叶青朝姜舒雅挥了挥手，后者问干嘛？
“我觉得问题出现在了感应贴片上。”
叶青指着屏幕上刚刚采集到的数据，“刚刚宇航想做出三指捏旋钮的动作，明明肌肉和神经释放出的生物电信号，与他想握住物体时的信号不同。可感应贴片依旧把它处理成最简单的张开手，再握住手。”
“复杂的，它处理不了。”姜舒雅深吸了一口气，小声道：“抓取物体，是手在生活中用到最多的功能。国内有些价值几千元的机械手，就只有这一种功能。”
“奥托博克这种，主要先进在传感器，和功能拓展方面。它的手指运动更灵活，手腕可以旋转，可以通过另一只手触摸机械手指，激活更复杂的动作。”
“为什么处理不了？”叶青打断道：“我拆过这种感应贴片，它里面用了金属电极来感应肌肉运动信号。理论上通过信号放大，它应该能感应到微伏数量级的生物电压变化。”
“如果害怕生活中的电子设备信号干扰，完全可以通过一个带屏蔽层的运动护腕，或其它东西来隔离掉。”
姜舒雅很无辜的看住了叶青，她听不懂。
“你们这里有奥托博克的技术员嘛，让他过来。”
“有，可是……”姜舒雅赶紧摇头。
义肢实验中心本来就是奥托博克公司投资建设的，里面三位负责人之一，就有位来自奥托博克公司的外派负责人。
但这次见面，姜舒雅并没通知奥托博克公司那边。
她主要担心奥托博克公司那边，上来就想拉着叶青谈合作，然后闹的整个医院领导都眼巴巴凑过来。
合作什么时候都可以谈，但第一次见面，姜舒雅还是希望能把精力用在产品的测试讨论上。
