Motivated by the ubiquity of control-affine systems in optimal control theory,
we investigate the geometry of
point-affine control systems with metric structures in dimensions two and three.
We compute local isometric invariants for point-affine distributions of constant type with metric structures for
systems with 2 states and 1 control and systems with 3 states and 1 control, and use Pontryagin's maximum principle to
find geodesic trajectories for homogeneous examples.
Even in these low dimensions, the behavior of these systems is surprisingly rich and varied.
