A practical expression of structural parameter,named stress comprehensive soil structure potential(stress-CSP),is proposed by some scholars, which,however,has its own limitations.

Advances in comprehensive structural potential and structural parameters of soils

A systemic method of structural synthesis was presented, which was used to achieve singularity-free fully-isotropic three-degrees-of-freedom spatial parallel mechanisms with 2T1R-type.

All possible 5-order motion screw systems of limbs’ structures were enumerated, and then a systematic method was presented for structural synthesis of 4-DOF (4-degrees-of-freedom) parallel manipulators with symmetrical structure.

Structural synthesis of parallel manipulators was considered on applying background of robot devices for positing and orientation in advanced manufacturing equips.

The theory of screws and reciprocal screws is used to analyze the constraint conditions for parallel robots of a given number of DOF, and a systematic method is proposed for structure synthesis of four-DOF parallel robots mechanisms.

In this paper, the concept of MEC,the MEC structure synthesis, structure economic control, and the closed loop control are surveyed.

To enlarge the fault tolerant workspace when robot\'s fault joint is locked,and improve the fault tolerant performance index,this paper used the influence factor as the fault tolerant index to conduct structure synthesis.
