Advanced Tactile Sensing for Robotics

Selectively stimulating skin receptors for tactile display

“…In all these efforts, researchers regarded one of the most attractive themes-the realistic display of tactile feelings-as work for the far future. Since human skin can distinguish very fine mechanical and geometrical properties, 6 many have felt it indispensable to prepare a sophisticated apparatus to control very fine pressure patterns. Actually, we suspect that previous pin arrays could not produce the realis-tic feeling of touching a texture even if the display caused vibratory sensations or displayed static macroscopic pin geometry.…”

Optical Three-Axis Tactile Sensor

“…Tactile sensors have been developed using measurements of strain produced in sensing materials that are detected using physical quantities such as electric resistance and capacity, magnetic intensity, voltage and light intensity (Nicholls, H. R., 1992). The optical tactile sensor shown in Fig.…”

Ein Beitrag zur Integration von Sensoren in eine anthropomorphe künstliche Hand mit flexiblen Fluidaktoren

“…Bei den auf das Greifen zielenden Projekten finden sich verschiedene Formen von Kraftsensoren, die die an einer oder mehreren Stellen wirkenden Kontaktkräfte bestimmen [108,109,139,196].…”
