Classification: CPC A  B | IPC A  B

Claim 0:
1. A robotic system comprising:
a base, including a computer;
a display electronically coupled to the computer;
a robot arm electronically coupled to the computer and movable based on commands processed by the computer;
an end-effector electronically coupled to the robot arm;
a dynamic reference base having at least three spaced apart posts;
tracking markers each adapted to be received in a corresponding post of the dynamic reference base;
a camera configured to detect the tracking markers,
wherein each of the tracking markers includes:
a circular disk having a circular reflective surface for passive reflection of light for optical recognition by the camera and a metallic element disposed at a center of the circular reflective surface for recognition by an imaging system;
a lower portion extending downwardly from the reflective surface and including a slot for receiving the corresponding post of the dynamic reference base; and
an annular ring frame circumferentially surrounding the circular disk and configured to provide optical contrast relative to the reflective surface of the circular disk;

wherein the computer includes an image processing application programmed to receive an optical image of the each tracking marker from the camera and to determine a center point of the circular disk which lies on a plane defined by the reflective surface based on the received optical image regardless of the orientation of the circular disk relative to the camera.
