Hybrid mobile robots, which combine the advantages of serial and parallel robots and have
the ability to realize processing in situ, have considerable application potential in the field of …

Accuracy is the most important index for the industrial applications of the Stewart platform,
which can be guaranteed by the kinematic calibration method to improve the motion orbit …

Zero offsets and geometric source errors will significantly degrade the kinematic accuracy of
redundantly actuated parallel manipulators (RAPMs). To relieve the influences of these …

Since kinematic calibration will induce variations in the structural parameter values, the
forward kinematics may have multiple or no solutions after calibration. This paper proposes …

The newly developed 4PPa-2PaR parallel mechanism has subchains on its limbs, and the
imperfect assembly process causes the kinematic error. The conventional matrix-based …

Pose adjustment mechanisms have been widely used in various fields such as aerospace,
marine transportation and industrial manufacturing. Strong coupling, small workspaces and …

This paper investigated the machining stability influenced by tool posture and position in ball-
end milling with parallel kinematic machine tool (PKM). Initially, the geometric structure was …

As the basic proportional-integral-derivative (PID) control with off-the-shelf control hardware
is still the widely used standard of industrial control practice, it is important to find some …

Parallel kinematics mechanisms (PKMs) offer advantages in terms of precision, rigidity, and
dynamics over their serial counterparts. However, achieving high accuracy in PKMs requires …

This research paper explores the application of topology optimization techniques in the
design of parallel kinematics mechanisms (PKMs) to achieve enhanced structural integrity …
