Question

Quizplus · Accepted Answer

In robotics and automation, the geometry where the repeatability is better than the accuracy can apply to all listed geometries: cylindrical, jointed spherical, Cartesian, and spherical. This is because repeatability refers to the robot's ability to return to a specific position under the same conditions, while accuracy refers to the robot's ability to reach a target position compared to the actual intended position. The mechanical design and control systems in these geometries can often be fine-tuned for high repeatability even if absolute accuracy is less achievable due to factors like backlash, flex, and calibration errors.
