A TWISTED AND COILED POLYMER ARTIFICIAL MUSCLES DRIVEN SOFT CRAWLING ROBOT BASED ON ENHANCED ANTAGONISTIC CONFIGURATION

A Twisted and Coiled Polymer Artificial Muscles Driven Soft Crawling Robot Based on Enhanced Antagonistic Configuration

Twisted and coiled polymer (TCP) actuators are becoming increasingly prevalent in soft robotic fields due to their powerful and hysteresis-free stroke, large specific work density, and ease of fabrication.This paper presents a soft crawling robot with spike-inspired robot feet which can deform and crawl like an inchworm.The robot mainly consists of

Transsplenic portal vein recanalization and direct intrahepatic portosystemic shunt placement to optimize liver transplantation

Abstract Background Percutaneous trans-splenic portal vein recanalization (PVR) has been reported for facilitation of transjugular intrahepatic portosystemic shunts (TIPS), however has not been applied to patients undergoing direct intrahepatic borstlist självhäftande portosystemic shunt (DIPS).We report the utilization of trans-splenic-PVR with

Computation Tree Logic with Deadlock Detection

We study the equivalence relation on states of labelled transition systems of satisfying the same formulas in Computation Tree Logic without the next state modality (CTL-X).This relation is obtained by De Nicola & Vaandrager by translating labelled transition systems to Kripke structures, while lifting the totality restriction on the latter.They cl
