Why is defining the tool center point (TCP) important?

Defining the tool center point (TCP) is crucial because it directly influences the accuracy of the robot's movements and its ability to interact with objects in its environment. The TCP represents the exact point on the tool where the robot applies force or interacts with other components, such as during welding, picking, or assembling tasks. By establishing this reference point, programmers can ensure that the robot positions its tool with precision, which is vital for tasks that require high accuracy. Accurate TCP definition helps avoid errors in operations, minimizes wear on tools, and optimizes productivity, leading to better overall performance of the robotic system.
