About this paper
Petr Švarný, Matěj Hoffmann
Artificial skin and peripersonal-space (PPS) models are examined as complementary tools for safer physical human–robot interaction. The discussion connects tactile contact localization with visual or depth-based anticipation of approaching people, while emphasizing that these technologies must be integrated with compliant hardware, fail-safe control, and certification under standards such as ISO 10218 and ISO/TS 15066.
Key insights
- Tactile sensing contributes to power-and-force-limited interaction by identifying where contact occurs, but it cannot by itself guarantee limits on force, pressure, energy, or stopping behavior.
- A PPS representation extends tactile awareness outward, linking the robot’s physical surface to pre-contact sensing and potentially enabling more adaptive protection than fixed exclusion zones.
- The central engineering challenge is not perception alone: useful systems must combine rich sensing with response-time guarantees, fault handling, safety-rated control, and formal validation.
