You can provide matlab code for sketching plot. Several studies have proposed an extravehicular robot that could move around in a NASA space station and perform physical tasks at various worksites. The arm is controlled by a unity feedback control with loop transfer function

$L(s)=G_c(s)G(s)=\frac{K}{s(\frac{s}{10}+1)(\frac{s}{125}+1)}$

a$.$ Sketch the Bode plot for $K=40.$

b$.$ Determine the frequency when $20log|L(j)|$ is $0$ dB $.$
