       abstract = "We derive an optimal control formulation for a nonholonomic mechanical system using 
         the nonholonomic constraint itself as the control. We focus on Suslov's problem, which is 
         defined as the motion of a rigid body with a vanishing projection of the body frame angular velocity 
         on a given direction {\$}{\$}{\backslash}varvec{\{}{\backslash}xi 
         {\}}{\$}{\$} $\xi$ . We derive the optimal control formulation, first for an 
         arbitrary group, and then in the classical realization of Suslov's problem for the rotation 
         group {\$}{\$}{\backslash}textit{\{}SO{\}}(3){\$}{\$} SO ( 3 ) . 
         We show that it is possible to control the system using the constraint 
         {\$}{\$}{\backslash}varvec{\{}{\backslash}xi {\}}(t){\$}{\$} 
         $\xi$ ( t ) and demonstrate numerical examples in which the system tracks quite complex 
         trajectories such as a spiral.",
