We have solved the arm motion interference coming after the scaling-down design of handle, and given a new way of articulated coordinated control to ensure the trace control.

The paper studies motion interference problem of T-type lifting mechanism from the perspectives of kinematics and dynamics, establishes simulative model of T-type lifting mechanism considering motion interference, analyzes the change of cylinder thrusts when the interference happens, and finally develops design module of T-type lifting mecha.

Geometric method is used here to analyze the knife-edge movement interference phenomena and the change law of knife gap in double-drum crop flying shear,and approaches to avoiding knife collision and determining the original knife gaps.

In the method,a fixed axis gear train is described with a mesh matrix,a clutch matrix and a transmission matrix;movement interferences are identified by the rank of the transmission matrix;and the transmission routes are obtained with a depth-first search(DFS) strategy in the transmission matrix.

On the noninterference moving condition of the cages of the vertical circulating parking equipment;

Various robot arm postures are planned and the kinematic interference constraint is analyzed.
