 ==== MTU ====
-According to the Hill-type muscle equations, we build the MTU model with Matlab simulink.
+According to the Hill-type muscle equations, we build the MTU model with Matlab simulink (Geyer2010).
+{{:guro_vtm_sim_block.png?200|}}
+The input of the MTU model is the length of the MTU (lmtu), muscle stimulation signal (STIM), and the rest signal (sigRest, rest the integrator when the system state changes (e.g. from flight to stance)). The output signals are the MTU states including muscle force (Fmtu), muscle length (Lce), muscle velocity (Vce), tendon length (Lse), and muscle activation (A).

 ==== Reflex ====
+Here's the overview of the simulink model which calculate knee joint torque based on joint angle.

+With the virtual muscle states from the MTU block, muscle stimulation signal is computed based on the linear combination of muscle force, length and velocity reflexes.
