SoftPot Rotary PotentiometerRotary potentiometer is provided at knee joint of the exoskeleton. Whenever the patient is having intent to walk, the rotary potentiometer calculates the respective torque. In response to that a feedback signal is provided to the actuation system to exert eq force to interact with the input torque. The feedback system is planed so s soundly that it updates the status of input torque in fraction of a arcsecond and as a result exoskeleton keeps working accordingly and works well with frequent torque changes.Rotary potentiometer works on the regulation of resistivity change. It is provided with a very fine needle/flip which rotates everywhere the resistive ring. More the angle of rotation more will be the value of resistance discovered between the terminal and the rotating flip. It is the measured resistance that tells about the angle of rotation of the joint and torques produced. Therefore, whenever rotational movement is observed the value of resis tance of the respective potentiometer is changed and the signal is fed to the ascendancy to take proper action. This helps in maintaining the exoskeleton motion according to the suggested profile and safekeeping it in the right motion.The rotary potentiometer used in our proposed design is SoftPot rotary potentiometer which is a miniaturized product with slim and sleek design. It stub easily be placed along the bearings of the rotary joints and gives output in terms of analog electrical signals which are proportional to the angle of rotation. This sensor is very thin and compact in design with a round-eyed range of operational resistances. Range of resistance change may go between 100Ohms to 10,000Ohms also the response of this sensor is much linear therefore, the positi... ...e with a frequency rate multiplied by the movement. When you rotate the gyroscope, you may peak a so called Coriolis acceleration. In fact, the gyroscope is a spinner, rotating around a vertical axis, f ixed in a frame which can articulated around horizontal axis, attached to another frame rotating around the triplet axis. Thus, we can conclude no matter how rotate a spinner, it unendingly has an ability to remain in the upright position. The transmitters accepts the signal about the spinners orientation course towards the frames, and the processor defines how the frame must be located with respect to gravity. regardless to the types of stabilization the system, it can be the power system stabilization (used in two-stage gyroscopes), the tracer system stabilization force (also on a two-level gyroscopes) and the power system stabilization (in three-stage gyroscopes)..
