In this overview of recent developments in the field biorobotics we cover materials such as use polyester fabric being used artificial skin and start whole new ways to actuate muscles a whole. this, discuss all relevant innovations from fields nano microtechnology, well soft robotics summarize what has been over last 4 years could be improved for future. The goal paper will gain better understa...

Pneumatic Artificial Muscles (PAM) are soft actuators with advantages such as high force to weight ratio, flexible structure and low cost. have inherent compliance that makes them feasible for exoskeletons rehabilitation robots. However, their nonlinear characteristics yield difficulties in modelling control actions, which is an important factor restricting use of PAM. The PAM associated nonlin...

Existing pneumatic artificial muscles generally rely on the use of either positive or negative pressure for actuation with each having their own advantages and disadvantages. Herein, a hyperbaric vacuum-based muscle (Hyper-VAM) making both pressures almost interchangeably is described. This done by placing actuator inside chamber which enables large deformations possible using pressure, forces ...

The use of silicone as an actuator that could serve as an artificial muscle to power underwater vehicles was analyzed. Muscles have attributes that are highly desirable for use in biomimetic underwater robots mimicking fish. They allow a more elegant design, optimized to move in the best way to produce thrust. Current artificial muscles are often inefficient, either in terms of power or in the ...

A new prosthetic hand with a fixed thumb and four fingers actuated by Shape Memory Alloy (SMA) type artificial muscle has been developed in this paper. Different from typical geared motor, SMA actuator is lightweight and silent, however shows a little short stroke and small attracting force per each unit. In order to achieve enough output force and motion range of each finger, multiple SMA type...

Artificial muscles define a large category of actuators we propose to analyze in a systemic framework by considering any artificial muscle as an open-loop stable system for any output which represents an artificial muscle dimension resulting from its “contraction”, understood in a broad meaning. This approach makes it possible to distinguish the artificial muscle from other actuators and to spe...
