“…To compensate the torque induced by the payload, the horizontal position of the counterweight is displaced along the y axis with the Y Stage up to position 2 to induce a torque with the same magnitude and opposite direction. For static balance on the roll axis of a payload with weight 1 and counterweight with weight 2 , the position 2 of the counterweight on the y axis must satisfy (1). This places the center of gravity of the payload-counterweight system on the vertical axis of symmetry of the inertially stabilized platform on the y-z plane as illustrated in Figure 2.…”

Energy efficiency is a salient design consideration for stabilization mechanisms when assembled on a battery-powered vehicle. In this paper we study the implementation of a two-axis gimbal with passive revolute joints for motion isolation of an inertially stabilized platform (ISP) mounted on a host vehicle. The objective is for the ISP to maintain a steady line of sight (LOS) of a payload placed in an arbitrary position on the ISP workspace by performing mass stabilization. The proposed method eliminates the need to operate gimbal motors throughout the operation of the host vehicle, stabilizing the platform LOS by relying on the gimbal passive joints acting as suspension to isolate the ISP from disturbancesimparted by the host vehicle. We describe the principle of operation and a prototype of the proposed stabilizing mechanism is presented.

“…The work presented in this paper is an extension of the stabilization method originally presented in IEEE SII2016 [1]. In the present work, we first discuss the method of elimination of moments of inertia to isolate the payload from external disturbance.…”
