Patent Images
1. A surgical robot system comprising:
- a robot having a robot base and a display, a robot arm coupled to the robot base, and an end-effector coupled to the robot arm, the end-effector having one or more tracking markers,wherein movement of the end-effector with respect to the robot base is electronically controlled by the robot;
and a camera stand including at least one camera able to detect the one or more tracking markers, the camera including at least one infrared signal detector that receives from the one or more tracking markers an infrared signal, wherein the robot determines a 3-dimensional position with respect to the camera stand of the one or more tracking markers based on the infrared signal,wherein the infrared signal includes a burst signal,and wherein the burst signal is transformed into an amplified signal and a reference signal,and a regeneration device compares the amplified signal to the reference signal to determine a voltage out waveform mimicking the burst signal to thereby determine the 3-dimensional position of the one or more tracking markers.

Abstract
An improved device for regenerating an infrared signal transmitted over the air for use in detecting a 3-dimensional position of an object. The regeneration device includes an infrared signal transmitter and detector that receives from the object a responsive infrared signal in response to the infrared signal transmitted by the transmitter. A low pass filter receives the responsive infrared signal from the detector and outputs a low-pass filtered signal. A comparator compares the output of the infrared signal detector and output of the low pass filter and generates an output representing a logic state based on the comparison.
