A minimally invasive surgery system including a robot, a cannula assembly and a computer system. The robot has at least one movable robot arm and the cannula assembly is detachably mounted to the robot arm. The cannula assembly includes a cannula and a pattern generating member. The cannula has a distal end and a proximal end with a flange portion and an elongate cannula shaft portion extending from the proximal end to the distal end and an access port through the elongate cannula shaft portion. The pattern generating member includes a pattern light source and a projector temporarily or permanently fixed to the cannula shaft portion. The pattern light source is operatively connected to the projector for projecting a light pattern. The computer system is configured for in real time receiving image data representing light pattern reflections from a surgical surface and for determining a real-time spatial position of the cannula assembly relative to the surgical surface.
