This paper presents a six-limb high-speed parallel robot for pick-and-place operations that is based on two Delta robots, where the two sub-platforms are connected by a gearbox. Unlike the current 6-axis Delta-type robot, all the actuators of the robot are mounted on a base platform, allowing to red…
This paper presents stiffness analysis of a family of three/four degree-of-freedom pick-and-place robots with four identical limbs. The Cartesian stiffness matrix of the robots is modeled with the virtual spring approach. By means of a nondimensionalization of the stiffness matrix, the 6 × 6 inhomog
This paper deals with the parametric optimum design of a parallel Schönflies-motion robot, named “Ragnar”, designed for fast and flexible pick-and-place applications. The robot architecture admits a rectangular workspace, which can utilize the shop-floor space efficiently. In this work, the parametr…
