Human Robot Collaboration

Tactile sensations are crucial for achieving precise operations. A haptic connection between a human operator and a robot has the potential to promote smooth human-robot collaboration (HRC). In this study, we assemble a bilaterally shared haptic system for grasping operations, such as both hands of humans using a bottle cap-opening task. A robot arm controls the grasping force according to the tactile information from the human that opens the cap with a finger-attached acceleration sensor. Then, the grasping force of the robot arm is fed back to the human using a wearable squeezing display. Three experiments are conducted: measurement of the just noticeable difference in the tactile display, a collaborative task with different bottles under two conditions, with and without tactile feedback, including psychological evaluations using a questionnaire, and a collaborative task under an explicit strategy. The results obtained showed that the tactile feedback provided the confidence that the cooperative robot was adjusting its action and improved the stability of the task with the explicit strategy. The results indicate the effectiveness of the tactile feedback and the requirement for an explicit strategy of operators, providing insight into the design of an HRC with bilaterally shared haptic perception.

Unique Context

Pictorial realism has long been considered necessary in aircraft landing displays because it makes effective use of man's superior perceptual capabilities. A serious limitation to pictorially realistic two-dimensional displays is that they must be magnified to provide distance cues equivalent to those provided in scenes viewed directly. This paper presents a rationale for applying some well known concepts including prediction, quickening, frequency separation, and percent of pursuit, to the development of forward-looking cockpit displays for low-visibility curved approach and landing tasks that may permit a compromise of the magnification principle. The development of such a display system provides a unique context for the systematic study of the interrelationships among these display concepts with a high potential for scientific and applied payoffs.
