都是成熟得很的MEMS器件。找个EE，做硬件整合的问问就知道了。
整合到电路板上很trivial.
农场的拖拉机，带autopilot的那种，Gyro都不止一个。 3D Acc.已经dirt cheap了，
gyro稍微贵点，有量也就$5上下的玩艺。

发帖数: 10701 | 18 大家帮我来看看我的物理模型。
iphone手机上有gyroscope, accelerometer 这些sensor。
我的想法是，用这些sensor来定量的测量golf动作中的一些技术特征。
比如，我用accelerometer画出的swing的动作，用加速度做纵坐标，时间做很坐标，一
个smooth的swing挺符合正弦曲线的 － 我把手机套在大手臂上。
如果我把手机套在手腕上，用gyroscope测出的的手腕翻转角速度，如果在乘以球杆的
长度，v= w(in rad/s) * r(in meter), 算出的数据也在理论的范围内。 （需要很多
修正）
比如，我在后院用sand wedge， 测出的我的rotation 角速度在z方向是max is 25 rad
/s
the club length of sand wedge is 35" - > 88.9cm = 0.89m
my club head speed in Z axis will be 0.89*25 = 22.25m.rad/s
1mph = 0.45m/s
so my wedge club speed in Z ... 阅读全帖 |

发帖数: 1640 | 19 看了一下那个Paper的PPT，他们的方法是假设Blurred Image = Sharp Image 卷积
Blur
Kernel + Noise，所以恢复Sharp图像主要就是从加速度Sensor和Gyroscope的数据估计
出那个
Motion导致的Blurring kernel，从而从Blured Image "Deconvolute" 出Sharp Image
不是专门搞这个，万一理解有误别见怪，呵呵。
他们的方法和原来的数码防抖技术比主要是考虑了相机动的过程中，景物不是相对成相面空间不变的，
因为相机旋转还会导致物体的深度发生变化，所以要加上Gyroscope测的6 DOF的角度变化。 |

发帖数: 2560 | 20 能看懂论文吗？顺着上次的连接，找了一篇：
http://faculty.ifmo.ru/butikov/Applets/Gyroscope.pdf
Precession and nutation of a gyroscope. by Eugene Butikov,
专门讲逆动（nutation）和陀螺转速的关系。大致就是转速足够大，而干扰力比较小，
可以想成轴向不变。
文章里把下表面看成摩擦力无穷大，等你都看懂了，做一些小调整，就是你说的情况了。
要写一篇论文才能讲清楚的问题，哪有人会在这里给你详细讲解。 |

The sensitive documents were released by Wikileaks last night ahead of
crucial international talks in Washington next month to discuss how to
tackle North Korea.

发帖数: 9459 | 37 The first known application of the universal joint occurred in China more
than 2,000 years ago. The Chinese had invented what we call “gimbals,” a
series of interlocking rings within a device that allowed a candle placed in
the center to remain upright regardless of the device’s position. Today,
gimbals are used to keep ships’ compasses level and as components in
gyroscopes.
