Abstract:For the maintenance the balance of a Robotics Device, we need to synthesize some parameters as follows centre of mass (COM), centre of pressure(COP), centre of gravity (COG), actuated motion, actuated pressure and actuated force (torque). This paper represents force diagram of human walking and standing related to the robotics device and proposed a force control system for robotics device's balancing during walking and standing. This control system can be effective for rehabilitation, to help various people bearing weak legs or to help those enduring from a broken leg, to walk. This can also be significant as a servitor device helping people carrying heavy loads. The main characteristic is that a paasive force balancer provides the force to preserve bodyweight. An actuator is required to shift the force during swing to stance (rehabilitaion). 1. Introduction In the recent time, researchers began to develop interfaces to discern the intention of the lower limb disabled people and to control robots using signals from muscles, brain or muscle activities. Previous studies have been reported on the dynamic signals such as forces and moments applied to handle walker, crutches and canes to assist walking. Research in aroused Robotics devices started exactly in the late 1960s.Robots are defined as standalone anthromorphic active mechanical devices that are ''held'' by an operator and work in concert with the operator's movements [1]. Robots are mainly used to increase performance of able-bodied wearer (e.g. for military applications), and to help disabled people to retrieve some motion abilities. Wearable robots to assist lower limb disabled people to walk have been developed and bio/kinesthetic sensors such as EMG, gyroscope, electro goniometer, tilt sensor and accelerometer have been used to control the Robotics. In the new organized society, the robotic device that can help the lower limb disabled walk. In order to produce a convenient Robotics for them, it needs to detect the implicit intention of the user and act accordingly [2]. However, there are little studies on sensing the natural walking intention of the user with a disabled lower limb and applying to the Robotics. Patients who survive a stroke quite often have less physical inability by the end of the initial three months. Utilitarian scales, for example, the Barthel Index and the Functional Freedom Measure (which measure the physical help or supervision required for self-care, including utilizing the can, dressing, showering, eating, and portability), tend to demonstrate a level of increases by three to four months after stroke, incompletely inferable from lack of care of the scale to further enhancements. Patients who no more need support by then may even now not able to utilize the influenced hand, stroll at velocities and separations that grant exercises outside the home, or live alone. Just 25 percent of patients return to the level of ordinary cooperation and physical working of group coordinated people who have not had a stroke. Some accident can be occurred during the activities in any PowerStation is a common scenario for the current situation [3-6]. The personal satisfaction has a tendency to be higher among patients with preferred working over among those with more regrettable working. The explicit walking intention is defined as a user's action for walking by user-defined as a rule's action for walking by user defined rule's mainly as start walking and stop walking and implicit walking intention as user's natural physical activities (such as muscle contraction, angle of ankle or knee joint) are detected by bio/kinesthetic sensors while walking without user's explicit operation. There are several types of most famous lower limbs Robotics newer, such as: • The BLEEX from U.C. Berkeley was designed to help soldiers to carry heavy packs. • Rewalk developed at Haifa University, Israel, is a fully aroused electrical Robotics, allowing paraplegic people to walk using crutches [7]. • HAL-3 developed at Tsukuba University is targeted for both Performance augmenting and rehabilitative purposes [8]. The motto of this study is to describe the control of Balancing and triggering method of lower limb Robotics by using force sensor, FSR, Pressure sensor and Gyro. Force sensing resistor is a material whose resistance changes when a force or pressure is
