Which two coordinate systems are primarily used in FANUC Handling Tool programming?

The correct answer identifies the Joint Coordinate System and the Robot Cartesian Coordinate System as the primary systems used in FANUC Handling Tool programming.

The Joint Coordinate System is based on the configuration of the robot's joints, allowing for precise control of the robot's movements relative to its physical structure. Each joint's position can be described by its angle or degree of rotation, providing an intuitive way to direct the robot based on its mechanical design. This system is particularly useful for programming movements that require the robot to articulate through complex positions.

On the other hand, the Robot Cartesian Coordinate System allows for positioning based on X, Y, and Z coordinates that represent the robot's workspace in three-dimensional space. This system is beneficial for tasks requiring precise placement or movement along straight lines in the workspace, offering straightforward calculations for programming and operation.

The combination of these two systems allows programmers to effectively control the robot's actions with both detailed joint movements and precise spatial placements, leading to enhanced versatility and efficiency in robotic operations within various applications.

Other coordinate systems mentioned in the options, such as polar, cylindrical, spherical, and geographic, do not align with the specific frameworks used in the context of FANUC Handling Tool programming, where precision and control over robotic movements are paramount.
