Figure Lengend Snippet: Robotic tribometer setup. (A) Real-world robotic tribometer: a six-axis industrial robot was used as actuator during friction testing, allowing the orthogonal positioning of a pin along the surface of a stationary sample mounted on a plate. The internal force sensor of the robot was used for load control, while the friction force was recorded with an additionally equipped high-precision force sensor. (B) Virtual robotic tribometer: a virtual representation of the robotic tribometer was created to perform offline motion programming in the robot’s simulation software. The position and orientation of the pin during testing was defined by a tool frame and tool center point (TCP).
