Some pointers to the literature:
For q-SO(3) If I am not mistaken, $SO(2)\approx U(1)$ has no nontrivial quantum deformation, but $SO(3)$ does; this is explicitly constructed in: Symmetries of quantum spaces. Subgroups and quotient spaces of quantum SU(2) and SO(3) groups, P. Podles (1994) Quantum SO(3) groups, P.M. Soltan (2008) For q-Sp(2):q-Sp(2), see Section 3.2 of Noncommutative families of instantons, G. Landi et al. (2008) [Section 3.2]2008). More general references on quantum classical groups: Quantum deformation of classical groups, T. Hayashi (1992) Quantum symmetric spaces and related q-orthogonal polynomials, M. Noumi and T. Sugitani (1995) Orthogonal and symplectic quantum matrix algebras and Cayley-Hamilton theorem for them, O. Ogievetsky and P. Pyatov (2005)
