Robot device for unloading cargo and control method thereof

A robot device, comprising:

• an end effector;
• a joint arm coupled to the end effector and configured to move the end effector;
• and
• a processor configured to execute a program stored in a memory so as to control movement of the end effector,
• wherein the processor is configured to:
• acquire cargo image information;
• control the joint arm to perform a first movement so as to move the end effector above a cargo elevation, the end effector including a body plate and at least one rod;
• control the joint arm to perform a second movement so as to move the end effector downward after the first movement;
• and
• control the joint arm to perform a third movement so as to retract the end effector after the second movement.

A method of operating a robot device for unloading cargo, wherein the robot device comprises a body plate and at least one rod coupled to the body plate, the method comprising:

• moving the rod above loaded cargo items;
• moving the end effector downward;
• and
• retracting the end effector.
