Soft robots possess an inherent mechanical compliance that enables safe and adaptive interaction with delicate structures and confined environments. However, their virtually infinite degrees of freedom introduce significant challenges in achieving precise and repeatable motion control. In laser-assi
Soft optical sensors hold potential for enhancing minimally invasive procedures like colonoscopy, yet their complex, multi-modal responses pose significant challenges.

Navigating through the peripheral lung branches poses a significant challenge in diagnosing lesions during bronchoscopy. Soft robots are well-suited to address current limitations in bronchoscopy due to their scale, dexterity, and adaptability. In this paper, we propose a real-time, semi-autonomous
In this paper, we present a fully soft miniaturized continuum robot that integrates 3D optical shape sensing through functionalized tubing used as soft optical waveguides. The sensor is fabricated by laser patterning an off-the-shelf medical tubing, allowing for bidirectional responses to large curv…
In neurosurgery, soft robots have the potential to introduce significant benefits over traditional metal tools for their ability to safely interact with delicate tissues. In this paper, we introduce a proof-of-concept soft, capacitive origami sensing module (OSM) that can measure forces during neuro…
Soft optical sensing strategies are rapidly developing for soft robotic systems as a means to increase the controllability of soft compliant robots. In this paper, we present a roughness tuning strategy for the fabrication of soft optical sensors to achieve the dual functionality of shape sensing co…
Robotic palpation shows significant potential to improve the accuracy and speed of tumor identification. How-ever, robotic palpation mechanisms often lack haptic feedback, making it difficult for the surgeon to identify variations in tissue stiffness. This paper presents a soft optical sensor integr…
This paper presents a proof-of-concept soft robotic glove that provides haptic feedback to the surgeon's hand during interventional endoscopy procedures, specifically colonoscopy. The glove is connected to a force sensing soft robotic sleeve that is mounted onto a colonoscope. The glove consists of…
Colonoscopy is the gold standard for colorectal cancer diagnosis; however, limited instrument dexterity and no sensor feedback can hamper procedure safety and acceptance. We propose a soft robotic sleeve to provide sensor feedback and additional actuation capabilities to improve safety during naviga
Burgeoning transendoscopic procedures, such as endoscopic submucosal dissection (ESD), provide a promising means of treating early-stage gastric neoplasia in a minimally-invasive way. However, the remote locations of these lesions, coupled with their origination in the submucosal layers of the gastr
This paper introduces a manufacturing technique which enables the integration of soft materials and soft fluidic micro-actuators in the Pop-up book MEMS paradigm. Such a technique represents a promising approach to the design and fabrication of low cost and scalable articulated mechanisms provided w
