Developments of Delta-Like Parallel Manipulators-A Review

Delta-like manipulator (DLM), which has many advantages of high stiffness, heavy load capacity, weak kinematic coupling and good dynamic performance, is a hotspot research of parallel robots with increasing attentions of scholars. Recent developments of DLMs are described with the discussions on kinematics, dynamics, performance and dimension synthesis in this paper, and prospects of future study with open problems are identified as well.
