Abstract.
In this research, the structural synthesis of first-class robot manipulators with general constraint one is investigated.
The number of constraints
𝑑 = 1
, and the mobility number
𝜆 = 5
for sphere-sphere combination of higher kinematic pair,
are investigated by using the analytical approach. Structural synthesis of new first-class robot manipulators is investigated
by using the transformations the higher kinematic pairs to the lower kinematic pairs. So, using this approach we get structural groups
with general constraint one. Also, kinematic structures and physical models of overconstrained robot manipulators are presented during
the research.
Keywords:
the mobility number, general constraint, higher kinematic pairs, transformations of kinematic pairs, overconstraint robot
manipulator.
As a result of the research process, the definitions for structural classification applied to robot manipulators have
been further refined during our study. First-class structural synthesis of robot manipulators which are constructed from
the geometrical transformation of the higher dyad (
𝑆
𝑆
) is described. During the research, new types of 2 structural group,
4 first class robot manipulators with general constraint one are structurally synthesized. Synthesized new types of robot
manipulators are presented with their physical and computer models and they can be used in industry, medicine, military,
space, and other areas.
