A mobility aid is provided. The mobility aid includes a mobile base movable along a mobile-base-movement plane, the mobile base having a plurality of wheels. The mobility aid also includes a seat pivotably coupled to the mobile base in a manner so as to be pivotable between a sitting disposition, in which the seat is oriented parallel to the mobile-base-movement plane, and a standing disposition, in which the seat is oriented perpendicular to the mobile-base-movement plane and a sitting surface of the seat is facing forward with respect to a forward-movement direction of the mobile base. The mobility aid also includes a balance-assist unit having a balance-assist-linkage mechanism coupled to the seat, and a body-support-module coupled to the balance-assist-linkage mechanism. Components of the balance-assist-linkage mechanism are jointed in a manner movable to allow movements of the body-support-module relative to the seat along a module-movement-plane parallel to the mobile-base-movement plane when the seat is in the standing disposition.

Various embodiments provide a handheld surgical instrument including a laser source configured to emit a laser beam for generating a laser marker on a surface, an inertial measurement unit configured to detect a motion of the handheld surgical instrument and generate a first signal including information on the motion of the handheld surgical instrument detected by the inertial measurement unit, and a movable platform for holding a controlled tool tip. The handheld surgical instrument additionally includes an actuator mechanically coupled to the movable platform, and a processing circuit configured to control the actuator to move the movable platform based on the first signal generated by the inertial measurement unit and a second signal generated by a vision unit based on a movement of the laser marker, so that the movement of the movable platform at least partially compensates a tremulous motion of the handheld surgical instrument.
