A tactile sensor for laparoscopic cholecystectomy
Surgical Endoscopy, 1997During laparoscopic surgery, surgeons observe the three-dimensional abdominal cavity on a two-dimensional TV monitor, which is a limitation. Another limitation is that surgeons are unable to estimate the softness of organs or tissues during laparoscopic surgery as they are only allowed to use instruments which touch objects and direct palpation is not ...

Superresolution with an optical tactile sensor
2015 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2015Although superresolution has been studied to huge impact in visual imaging, it is relatively unexplored in tactile robotics. Here we demonstrate a novel optical sensor design (the TacTip) capable of achieving 40-fold localization superresolution to 0.1mm accuracy compared with a 4mm resolution between tactile elements.

Tactile Behaviors with the Vision-Based Tactile Sensor FingerVision
International Journal of Humanoid Robotics, 2019This paper introduces a vision-based tactile sensor FingerVision, and explores its usefulness in tactile behaviors. FingerVision consists of a transparent elastic skin marked with dots, and a camera that is easy to fabricate, low cost, and physically robust.

The authors aim to realize a "Cell Tactile Sensor" which is integrated tactile receptors built by cultured cells. We regard the cells cultured on the PDMS membrane as the force receptors. We here report on interesting experimental results as follows: at first, we designed the positions of cells by self-organization which is due to mechanical ...

Processing of an Embedded Tactile Matrix Sensor
2006 IEEE International Conference on Robotics and Biomimetics, 2006A fully embedded tactile/force sensor system to be installed on the phalanges of a robot hand is presented in this paper. The sensor consists of a distributed array of analog tactile elements and an integrated three-component force transducer with embedded analog and digital electronics. The tactile sensor is a matrix of electrodes etched on a flexible

Optimal tactile sensor placement
Proceedings, 1989 International Conference on Robotics and Automation, 2003By intelligently locating a tactile sensor with respect to a sensed object it is possible to minimize the number of sensed points required to identify or localize the object. The author applies principles of statistical decision theory to determine the optimal sensing location to constrain an object model, maximally based on any prior object ...

Proceedings. 1987 IEEE International Conference on Robotics and Automation, 2005
A new design of robot tactile sensor is described which features a highly compliant structure. Sensor compliance accommodates a degree of inaccuracy in robot positioning, aids stable grasping and resists damage. Silicone rubber sheet forms the outer skin of the sensor which is supported by a core of polyurethane foam.

A tactile sensor which simultaneously provides a compliant interface between a support element and an object to be handled (i.e., a robot gripper in a delicate component), and identifies the contact force and the contact pattern between the object and the support element.
