Description: The motion control is very simple. Adding an incremental position to the position set point on a periodic basis essentially sets the velocity. In the following code I broke out the "AddToPosition" so that Dilbert s wall following and line following code could "adjust" the relative wheel positions

Description: 绘制庞加莱截面图的程序。先通过solveLor.m来求出一系列点，然后代入Poincare_section 程序绘制庞加莱截面。
通过观察Poincare截面上截点的情况可以判断
是否发生混沌：当Poincare截面上有且只有一个不动点或少数离散点时，运动是周期的；当Poincare截面上是一封闭曲线时，运动是准周期的 当Poincare截面上是一些成片的具有分形结构的密集点时，运动便是混沌。 -Poincare section drawing program. First obtained by solveLor.m to a series of points, and then drawn into the program Poincare Poincare section. By observing the situation on the Poincare section cut points can determine whether chaos occurs: When there is only one fixed point or a few discrete points on the Poincare section, the motion is periodic When is a closed curve on the Poincare section, the motion is quasi- When is the point of having a dense fractal structure on some stretches of the Poincare section, the motion is chaotic period.

Description: In the walking process, the human body shows regular periodic motion, especially upper and lower limbs, which reflect the individual’s unique movement pattern. Human gait is an attractive modality for recognizing people at a distance. Compared to other biometrics, gait has some unique characteristics. The most attractive feature of gait as a biometric trait is its unobtrusiveness, i.e., the fact that, unlike other biometrics, it can be captured at a distance and without requiring the prior consent of the observed subject. Most other biometrics such as finger prints, face, hand geometry, iris, voice, and signature can be captured only by physical contact or at a close distance the recording probe.-In the walking process, the human body shows regular periodic motion, especially upper and lower limbs, which reflect the individual’s unique movement pattern.

For 270 nA. Unlike using periodic sampling to achieve low power dissipation, accelerometers are different,
ADXL362 does not aliasing input signals via undersampling; it uses full data speed
The rate is sampled across the entire bandwidth of the sensor)

The bifurcation, quasi periodic motion and sub harmonic oscillation in ferromagnetic resonance circuit can be discussed through the Duffing equation.
