1. A surgical system, comprising:
a cutting tool having an attached tracker;
a planar mechanism having a first end connected to the cutting tool;
an actuation unit connected to a second end of the planar mechanism, the actuation unit for adjusting a position and orientation of the cutting tool, wherein the actuation unit has a serial architecture and at least three motorized degrees of freedom;
a passive articulated lockable holding arm connected to the actuation unit; and
a control unit configured to:
determine a pose of the cutting tool using data from sensing of the tracker;
determine a cutting plane based on the pose of the cutting tool;
detect whether the cutting plane can be aligned with a target plane for an anatomical structure of a patient, wherein the cutting plane is orthogonal to a plane defined by the planar mechanism; and
if the cutting plane can be aligned with the target plane, control the actuation unit to bring the cutting plane into alignment with the target plane.
