In this paper, a novel recursive method to identify the moment of inertia parameters of on-orbit spacecraft is proposed. Different from the frequently-used momentum conservation and least squares approach, the presented method is implemented based on the Projection Approximation Subspace Tracking (PAST), and the moment of inertia parameters can be determined recursively from the system state-space...
A roboticized rock abrasion tool is considered to replace the geologistpsilas rock hammer to remove dusty and weathered surfaces of the rock. A roboticicized rock abrasion tool with three degrees of freedom has been developed in this paper. Planetary transmission system is used in the grinding driving system with two inputs (rotation motor and revolution motor) and two outputs (grinding wheel and...
