Abstract:
Advanced robotics engineering, which is gaining attention as a solution to the decline in the labor force, still faces a major challenge due to its immature object manipulation capabilities. Hence, our research team introduces an artificial robotic fingertip equipped with a highly sensitive tri-axial force tactile sensor, designed to enhance the object manipulation capabilities of robots. The tri-axial force sensor array embedded in the fingertip features a hybrid structure that combines the high sensitivity of single-crystal silicon with the excellent mechanical properties of polymer-based rubber. Through a series of evaluations, the developed sensor demonstrated linear output within a measurable range (~1.2 N), high sensitivity, and outstanding fundamental characteristics, such as low hysteresis and repeatability errors. Furthermore, it exhibited the ability to detect forces along each of the three axes independently, without mutual interference.
