Classification: CPC A  B | IPC A  B

Claim 10:
11. 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, the end-effector including a quick-connector;
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 housing having an upper portion and a lower portion;
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, the circular disk being made of metal for recognition by an imaging system; and
an annular ring frame circumferentially surrounding and disposed over the circular disk and configured to provide optical contrast relative to the reflective surface of the circular disk, wherein the circular disk is part of the lower portion and the ring frame is part of the upper portion, wherein the lower portion extends downwardly from the reflective surface and includes a slot for receiving a post of an array fixture; and

wherein the upper portion and the lower portion are coupled via a snap-fit connection;
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.
