Action Augmentation of Tactile Perception for Soft-Body Palpation

Abstract: Medical palpation is a diagnostic technique in which physicians use the sense of touch to manipulate the soft human tissue. This can be done to enable the diagnosis of possibly life-threatening conditions, such as cancer. Palpation is still poorly understood because of the complex interaction dynamics between the practitioners' hands and the soft human body. To understand this complex of soft body interactions, we explore robotic palpation for the purpose of diagnosing the presence of abnormal inclusions, or t… Show more

“…Control of sensor response can allow us to better discriminate between different stimuli, whether from control of the hand-environment interactions to amplify the desired response [74], or by actively controlling the morphology to sense different properties [75]. In summary, exploiting a passive soft body for sensing and perception offers perhaps the biggest challenge in the passive hand framework and is the area least explored.…”

“…Actuation and perception can be considered as an integration. 10,11 When an object interacts with the environment, the tactile measurements ultimately depend on the sensor configurations, especially in soft sensors. In other words, the physical property of the sensor/agent acts as a physical reservoir that filters the tactile information for active sensing.…”

“…14 Incorporating actuation in perception shows a new trend to develop robotic counterparts to understand the environment more effectively. 11 Another example can be found in active haptic exploration to localize a nodule in soft tissue with a tunable-stiffness robotic probe. 15 Examining the tissue with different stiffness of the probe can significantly reduce the uncertainty of the measured haptic information, thus, more effective in the detection.…”

“…Previous studies in the field of filter-based tactile sensing have focused on the effect of the filter’s morphology on the structure and quality of the recorded data, investigating the information gain’s maximization ( Thuruthel et al, 2020 ), the amplification of the sensor’s sensitivity ( Fend et al, 2004 ), task-specific optimization ( Qi and Hirai, 2019 ), and the relationship between redundancy and localization error ( Costi et al, 2021b ). Moreover, researchers have deeply studied the relationship between the morphology of the sensor and the action for perception ( Huang et al, 2019 ; Scimeca et al, 2020b , 2021 ). From their results, it emerges how in action–based perception is strongly affected by the morphology of the tactile filter ( Bernth et al, 2018 ) and the inevitable trade-off when selecting the material of the filter.…”
