Intention detection using physical sensor & Electromyography.
Introduction
the development of medical technology has increased the lifespan of human beings and as a result the number of people who feel not well or discomfort.
To solve the inconvenience studies are underway on exoskeletons to the assist they join.
We take a paper and in this paper we present a knee exoskeleton because the knee is vulnerable to wear aging. Which is difficult to treat in the addition the knee is joint frequently use in our real life and deals with a lot of things.
The knee is a complicated structure, so it is very difficult to use as an exoskeleton on the knee and as a result of that structure the center of rotation changes with some movement of knees. If the exoskeleton is designed without considering to the change of the center of rotation and the range of the motion of the user is limited to particular time.to solve some problem in that exoskeleton considered complex knee movement to have been studied.it is carried to by use a link of system to self align and that use Schmitt coupling to accommodate large radial displacement between two shafts and when however. Sometime exoskeleton have many disadvantages and in that the volume of the actuator is very high. There are maxima that have a prismatic degree of freedom to self align with the complex movement of knees. Due to this the exoskeleton does not limit wearer’s range of the motion.in this the paper is proposed exoskeleton has the structure which measure

Abstract
we present a knee exoskeleton due to the complicated structure of the knee an exoskeleton can limit the wearer movement.to prevent this exoskeleton is prevented this by move its ankle part.in addition of wearer the developed exoskeleton is designed to move the ankle part. The developed exoskeleton could be worn on only one leg but in this case it is very difficult to detect the intention because the relative relationship of both legs are different, or we can say unknown in addition we can add EMG sensor which detect the success rate of intention which is increased to 92% and the intention detection was also 27.1 ms faster to average.
The anatomical motion of the knee.
Knee is composed of many things such as femur, tibia, and extra articular structure but since the movement of the knees is very complex and is reprinted by 6 degree of freedom however, extension and flexion account for the most movement of the knee joint.
The movement of the leg is made by moving the egg-shaped femur back forth on the flat tibia plane. Due to the contact point movement and tibia are exact bone shaped, the center of the rotation of the knee changes as the legs moves. And the LBKA is changed’for this change the movement of exoskeleton with the center of rotation is aligned of the wearer. 
EMG Filtering
EMG measures the action potential of the muscle fiber include by the action fiber in muscle neuron in our body because 1 motor neuron dominates multiple muscle fiber which is measured simultaneously through the electrode.it is measured by various factor which is responsible for that. The EMG data is integrated for filtering because of the value obtained by integrating correlates with our muscle contraction which forces the wearer. The voice of the EMG is also removed by this filter. The filter process is expressed as
