An Exhaustive Study of the Workspace Topologies of all 3R Orthogonal Manipulators with Geometric Simplifications
This paper analyses the workspace of the three-revolute orthogonal manipulators that have at least one of their DH parameters equal to zero. These manipulators are classified into different groups with similar kinematic properties. The classification criteria are based on the topology of the workspace. Each group is evaluated according to interesting kinematic properties such as the size of the...
متن کاملA Workspace based Classification of 3R Orthogonal Manipulators
A classification of a family of 3-revolute (3R) positioning manipulators is established. This classification is based on the topology of their workspace. The workspace is characterized in a half-cross section by the singular curves of the manipulator. The workspace topology is defined by the number of cusps and nodes that appear on these singular curves. The design parameters space is shown to ...
متن کاملOptimization of the Workspace Volume of 3r Manipulators Using a Hybrid Methodology
A fundamental feature of a manipulator is the capacity of its workspace because it influences on the manipulator design, in the manipulator position in the work environment and in the its dexterity. In the case of 3R manipulators, it is represented by a revolution solid. Thus, in this paper the workspace volume is calculated based on the area of its radial section. An optimization problem is fo...
متن کاملMaximal Operational Workspace of Parallel Manipulators
Parallel manipulators are an interesting alternative to serial robots given the important mechanical and kinematic advantages offered. Nevertheless, they often present more complex and smaller workspaces with internal singularities (Altuzarra et al., 2004; Gosselin & Angeles, 1990). Thus, the workspace size, shape and quality are considered some of the main design criteria of these robots (Merl...
متن کاملClassification of one family of 3R positioning Manipulators
The aim of this paper is to classify one family of 3R serial positioning manipulators. This categorization is based on the number of cusp points of quaternary, binary, generic and non-generic manipulators. It was found three subsets of manipulators with 0, 2 or 4 cusp points and one homotopy class for generic quaternary manipulators. This classification allows us to define the design parameters...
