Thrilled to share our newly accepted paper in IEEE Transactions on Medical Robotics and Bionics<\/em>, where we introduce a soft, endoscope-deployable microfluidic suction robot<\/strong> that combines multimodal intraluminal locomotion<\/strong> with localized aspiration and sampling<\/strong> for targeted mucus clearance and liquid biopsy.<\/p>\n\n\n\n

\ud83e\udde0\u2728 What we developed:<\/strong><\/p>\n\n\n\n

A soft intraluminal robotic platform <\/strong>that:<\/p>\n\n\n\n

\ud83d\udd39 Integrates Locomotion + Sampling: A pneumatically controlled 2\u00d72 pouch matrix for multimodal actuation, paired with an independent microfluidic suction module for active liquid extraction and sample recovery.<\/p>\n\n\n\n

\ud83d\udd39 Enables Stable Pitch Control: A balloon-based pitch control mechanism improves controllability for intraluminal operation, with the best overall performance observed at an initial pressure range of 2\u20133 kPa.<\/p>\n\n\n\n

\ud83d\udd39 Balances Compliance and Safety: Single-pouch characterization guided the selection of a 2 mm pouch radius, achieving up to 246.91% maximum deformation; burst tests show a system safety factor \u2248 5.27 under the reported operating conditions.<\/p>\n\n\n\n

\ud83d\udd39 Targets Real Clinical Pain Points: Designed for constrained lumens (e.g., distal airway) where conventional airway clearance approaches struggle with reach and effectiveness.<\/p>\n\n\n\n

\ud83c\udfaf Key Results:<\/strong><\/p>\n\n\n\n

\u2705 Multimodal mobility: Differential actuation achieves 26.9 mm\/min forward speed and 4.86\u00b0 yaw per drive cycle.<\/p>\n\n\n\n

\u2705 Robust suction across viscosities: Efficiently extracts 20\u201380% glycerol solutions within 10 s (via parameter tuning).<\/p>\n\n\n\n

\u2705 In vivo feasibility: Endoscope-assisted porcine validation confirmed sequential pouch-driven motion and successful recovery of biological samples containing mucus and tissue fragments after saline irrigation.<\/p>\n\n\n\n

\ud83d\udca1 Why it matters:<\/strong><\/p>\n\n\n\n

This work demonstrates a compliant, integrated \u201cmove + anchor + suction\u201d<\/strong> approach for narrow lumens\u2014supporting safer localized intervention and sampling, with a path toward distal airway translation.<\/p>\n\n\n\n

\ud83c\udf31 What\u2019s next?<\/strong><\/p>\n\n\n\n

We\u2019re moving toward more automated closed-loop pneumatic control, improved steerability\/navigation, and miniaturization for deeper airway access\u2014while expanding validation in airway-specific models.<\/p>\n\n\n\n
