Spletwhere M(q) is the mass matrix, C(q,q˙) is the Coriolis and centrifugal term of the equation of motion, and Q is the vector of generalized forces for all the degrees of freedom (DOFs) in the system. M only depends on q and C depends quadratically on q˙. 4. How do we derive M and C from Equation (13)? Let us go back to the velocity of one
