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) = Ge(s)G(s) K s(s/8+ 1) (s/120 + 1)

Sketch the Bode plot for K = 20 and determine the frequency when 20 log|L(jω)|is 0 dB.

L(s) = Ge(s)G(s) K s(s/8+ 1) (s/120 + 1)
