In order to effectively decrease the joint-angular drifts and end-effector position
accumulation errors, a novel adaptive fuzzy recurrent neural network (AFRNN) is proposed …

In this paper, the dynamics model of the 3-Degrees-Of-Freedom (DOF) Delta parallel
manipulator is elaborated by means of a Screw-based formulation of the virtual works …

In this paper, the kinematics, dynamics, and load distribution algorithm of a 4-PPPS
redundantly actuated parallel manipulator are investigated with the screw theory. For the …

This paper presents a novel framework for the analysis of a 3-RRR spherical parallel
manipulator with coaxial input axes (coaxial SPM) with the focus on its infinite rotational …

Nowadays haptic devices have lots of applications in virtual reality systems. While using a
haptic device, one of the main requirements is the stable behavior of the system. An …

Current research on spherical parallel mechanisms (SPMs) mainly focus on surgical robots,
exoskeleton robots, entertainment equipment, and other fields. However, compared with the …

This paper investigates a comparative kinematic analysis between nonredundant and
redundant 2-Degree Of Freedom parallel manipulators. The nonredundant manipulator is …

Pose accuracy is one of the most important problems in the application of parallel robots. In
order to adhere to strict pose error bounds, a new kinematic calibration method is proposed …

Singularity analysis of parallel manipulators is an active research field in robotics. The
present article derives for the first time in the literature a condition under which a five-bar …

Robot-assisted reduction of pelvic fracture requires large workspace and large load
capacity. A kind of six degree-of-freedom (DOF) robot for pelvic fracture reduction is …
