Optical-Waveguide Based 3-Axial Tactile Sensor for Minimally Invasive Surgical Instruments

RA-L 2024

Force feedback is of importance in Minimally Invasive Surgery (MIS) as it reduces surgical risks and enhances surgical safety. However, equipping force sensing to the tip of surgical instruments presents challenges due to their diminutive dimensions and often curved shapes. To address this issue, a

Human Behavioral Metrics of a Predictive Model Emerging During Robot Assisted Following Without Visual Feedback

RA-L 2018

Robot-assisted guiding is gaining increased interest due to many applications involving moving in the noisy and low visibility environments. In such cases, haptic feedback is the most effective medium to communicate. In this letter, we focus on perturbation-based haptic feedback due to applications

Feasibility study- novel optical soft tactile array sensing for minimally invasive surgery

IROS 2015poster

The absence of touch of sense is a widely known drawback of robotic minimally invasive surgery (MIS). This paper proposes a design of optic soft tactile arrays which is promising to be adapted for MIS. The proposed design consists of multiple soft material channels. Each channel is designed using th…
