Abstract: Systems and methods according to present principles provide for three axis force sensing in a convenient and manufacturable way. In one implementation, a vibrating motor is attached at the fixed end of an anisotropic structure, such as a rod, which then vibrates in a circular motion. A monitor such as a 3-axis accelerometer is also attached to the anisotropic structure. The resulting motion is then mapped electronically for analysis. With no force applied, a circular motion is achieved. When a net force is applied to the free, vibrating end of the rod, the circular pattern which is traced out becomes distorted, e.g., progressively flattened into an ellipse, in a repeatable way which is directly proportional to the applied force. The axis of the applied force can be ascertained according to the direction in which the ellipse forms. Systems and methods according to present principles may be used in any application in which force sensing is needed, e.g., robotics, including robotic surgery.
