About this Research Topic
The sense of touch is fundamental for humans to perceive and react to dynamic phenomena in the real world. With the expansion of robotics into new application scenarios, the need to provide robots with this sensing modality is significantly increased, which has encouraged the response of the scientific community to study and develop technological solutions for the design of a wide range of tactile sensing solutions. The sense of touch entails important aspects (e.g., control, safety, perception, synergy with other sensing modalities) that go beyond the availability of a specific technology and can be exploited in new domains (human-robot interaction, workspace exploration, reactive behaviors, etc.).
This Research Topic wants to focus on new classes of robot manipulation and control problems, tasks, and applications featuring tactile feedback as the main sensing modality, and its role when intertwined with other sensing modalities.
In the future, robots will be expected to manipulate objects characterized by uncertain characteristics, such as mass, softness, friction, operating in poorly or non-structured environments where unplanned contacts may arise, or interacting with humans to physically collaborate when executing joint tasks. There is a gross imbalance in the techniques used to address these problems by relying on technologies like machine vision, but in all these conditions, tactile sensing is bound to play a key role to ensure safe operations either alone or in synergy with other sensing modalities. As possible examples, reactive tactile-based control algorithms can help deal with unexpected contacts, tactile-based gesture recognition can improve interactions with humans, whereas tactile sensing can provide information about mechanical characteristics of the objects the robot is in contact with, and improve recognition/classification in manipulation and exploration tasks.
This Research Topic is aimed at closing the gap and contributing to tactile sensing as a mature robot technology. In particular, the aims are:
● to highlight the potential of new tactile-based solutions to approach new robot applications
● to present new algorithms and new robot tasks whereby tactile sensing can be effective and unique
● to exploit the role of tactile sensing and perception in robot cognitive tasks, and finally
