Self-excited air flow passage changing device for periodic pressurization of soft robot

Design and control of a soft, shape-changing, crawling robot

Soft materials have many important roles in animal locomotion and object manipulation. In robotic applications soft materials can store and release energy, absorb impacts, increase compliance and increase the range of possible shape profiles using minimal actuators. The shape changing ability is also a potential tool to manipulate friction forces caused by contact with the environment. These ad...

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Novel Self-Oscillating Polymer Actuators for Soft Robot

Power Flow Modelling of a Self-excited Induction Generator

which a generating plant driven by renewable energy sources, such as wind energy, is connected to partially serve loads. This research demonstrates the induction generator by two forms: i) power (PQ) model and ii) admittance (Y) model. Solution convergence and model accuracy are observed in order to predict power flow distribution through feeder lines resulting from the grid connection of a ren...

Design of Air Distribution System for Operation Theatre Using Flow Visualization Techniques to Improve Flow Characteristics

Operation Theatre (OT) is the most important area where precise controlled on indoor air quality is required because it is directly related to patient health and its recovery period. This work aims to study and visualize the airflow distribution of conventional flat air diffuser ventilation system and newly designed angular air ventilation system in OT. Angular Air Distribution (AAD) system is ...
