Background:

Mobile manipulators offer advanced capabilities in surgery and tool delivery.
Optimizing access to the operating field is crucial for surgical procedures.
Avoiding manipulator singularities is essential for safe and efficient operation.

Purpose of the Study:

To develop a motion planning method for mobile manipulators in surgical applications.
To enable optimal positioning for improved surgical field access.
To maximize manipulator manipulability and avoid singularities during planned procedures.

Main Methods:

Motion planning based on a penalty function approach.
Redundancy resolution at the acceleration level.
Parameterizing end-effector paths without requiring a mobile platform trajectory.

Main Results:

Demonstrated a method for planning mobile manipulator motion to maximize manipulability.
Successfully avoided manipulator singularities through optimized path planning.
Considered constraints including mechanical limits, collision avoidance, and control limitations.

Conclusions:

The proposed motion planning method enhances the utility of mobile manipulators in surgical settings.
Optimizing for manipulability ensures safer and more effective manipulator operation.
The approach is validated through a computer example with a nonholonomic platform and a 3-DOF manipulator.
