What is required to ensure the TCP maintains a "straight" path while checking Position Variables?

The concept of maintaining a "straight" path while checking Position Variables in a TCP (Tool Center Point) operation revolves around the type of coordinate system being utilized. When a system is set to joint coordinates, it allows for the control of each individual joint of the robotic arm independently. This configuration is essential for achieving precise movement along the set path without introducing any unwanted deviations or curves that could arise from other types of coordinates.

Using joint coordinates means that the robot's movement is calculated based on the angles and positions of its joints rather than trying to achieve a straight movement through the Cartesian space. By commanding the joints to move to specific angles that correspond to the desired straight path, the robotic arm can ensure that the TCP travels along a predictable and reliable trajectory.

In contrast, other coordinate settings like cylindrical or position coordinates may not provide the same level of control over joint-specific movements. Cylindrical coordinates work with a combination of rotational and linear movements that can lead to non-linear paths, and position coordinates typically refer to absolute positions in space without the detailed joint control necessary for ensuring straight-line movement. Turning off all servos would entirely disable the motion control, making it impossible to check positions or maintain any path.

Thus, utilizing joint coordinates is the appropriate choice for
