What does 'tool center point' (TCP) define in KUKA robots?

The concept of 'tool center point' (TCP) is fundamental in robotic applications, especially in the context of KUKA robots. The TCP defines the position and orientation of the tool that is attached to the end effector of the robot. This point is crucial because it serves as a reference for the robot's movement and operation in a three-dimensional workspace. When programming the robot or configuring its path, the TCP allows for precise control over where the tool interacts with objects, ensuring accuracy in tasks like welding, painting, or assembly.

Understanding that the TCP includes both the position and the orientation of the tool provides insight into how the robot performs complex tasks. For example, if the robot is programmed to pick up an object, knowing the TCP helps to calculate exactly where the end effector needs to move and at what angle the tool needs to be positioned for a successful operation.

In contrast, the other options do not accurately reflect the role of the TCP. While safety zones, control interfaces, and weight limits are essential aspects of robotic operation, they do not encompass the specific characteristics of the tool's placement and alignment, which is the essence of what the TCP represents. The TCP directly relates to how effectively the robot can manipulate tools and perform its designated
