SoftPot Rotary PotentiometerRotary potentiometer is provided at knee vocalize of the exoskeleton. Whenever the patient is having intent to walk, the rotary potentiometer calculates the watch overive torque. In response to that a feedback signal is provided to the actuation system to exert equivalent force to move with the input torque. The feedback system is purposeed so well that it updates the status of input torque in fraction of a second and as a bequeath exoskeleton keeps working accordingly and works well with frequent torque changes.Rotary potentiometer works on the principle of resistance change. It is provided with a very handsome needle/flip which go arounds over the resistive ring. More the angle of rotation more will be the value of resistance observed between the rod 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 resistan ce of the respective potentiometer is changed and the signal is supply to the controller to take proper action. This helps in maintaining the exoskeleton motion according to the suggested profile and keeping 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 can easily be placed along the bearings of the rotary joints and gives output in name of analog electrical signals which are proportional to the angle of rotation. This sensor is very thin and compact in design with a wide range of practicable resistances. Range of resistance change may vary between 100Ohms to 10,000Ohms also the response of this sensor is much linear therefore, the positi... ...e with a frequency rate cipher by the movement. When you rotate the gyroscope, you may notice a so called Coriolis acceleration. In fact, the gyroscope is a spinner, rotating around a vertical axis, fixed in a fram e which can articulate around horizontal axis, attached to another frame rotating around the third axis. Thus, we can conclude no matter how rotate a spinner, it always has an ability to remain in the upright position. The transmitters accepts the signal about the spinners orientation 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 forefinger system stabilization (in three-stage gyroscopes)..
