Abstract
Tactile sensing is essential for any haptic interaction of robots and robotic systems with their environments. Throughout this work we introduce a tactile sensing solution based on a MEMS pressure sensor consisting of an array of flexible sensor cells, which enables spatially resolving force and contact pressure measurements over a wide dynamic range at high resolution. A compelling feature of the developed sensor concept is its soft and “human-like” mechanical touch behavior, which can solve challenges regarding the handling of sensitive objects, human-like tactile perception in prosthetics, or human-robot interaction scenarios. The developed sensor solution is characterized and evaluated in a typical collaborative robot work scenario in the industry for the gripping and lifting of objects with a commercial industrial robot system.
