Two-eye device for robot

A two-eye device for a robot comprising:

• a base;
• a left camera on an upper side of the base;
• a right camera on the upper side of the base, wherein the right camera is to the right of the left camera;
• a motion generating device comprising a main shaft, wherein the motion generating device is configured to cause the main shaft to perform a linear movement, a rotation, and a helical movement;
• a left-and-right tilting mechanism connected to the motion generating device and configured to simultaneously tilt the left camera and the right camera by an angle in a left or a right direction based on the main shaft performing the linear movement in a direction parallel to the base;
• an up-and-down tilting mechanism connected to the motion generating device and configured to simultaneously tilt the left camera and the right camera upward or downward by an angle relative to the base based on the main shaft performing the helical movement;
• a focus adjusting mechanism connected to the motion generating device and configured to adjust a focal angle between the left camera and the right camera based on the main shaft performing the rotation;
• and
• a first motor and a second motor configured to operate the motion generating device.
