On the general motion-planning problem with two degrees of freedom [PDF]
Discrete & Computational Geometry, 1988 The problem of motion planning for two-degree-of-freedom systems is considered when obstacles to be avoided are bounded in configuration space by an arrangement of simple Jordan arcs. The existence of the continuous motion path connecting given initial and final configuration in a cluttered workspace is the issue, then the motion planning problem is ...

Annals of Biomedical Engineering, 2022 Six kinematic parameters are needed to fully describe three-dimensional (3D) bone motion at a joint. At the knee, the relative movements of the femur and tibia are often represented by a 1-degree-of-freedom (1-DOF) model with a single flexion–extension ...

Singular Aspects of General Planar Motions with Two Degrees of Freedom [PDF]
The International Journal of Robotics Research, 1998 General planar motions with two degrees of freedom differ funda mentally from those with one degree of freedom, in that they may exhibit "cross-caps" singularities. At such singularities the trajec tories fail to exhibit four of the generic singularity types normally associated with such motions, namely, lips, beaks, and two of their degenerations ...

Design of a Rotary-Linear Motor With Unipolar SPM and Voice Coil Structure
IEEE Access, 2020 In this article, a rotary-linear motor that achieves rotary and linear motions with a simple one-air-gap structure, low rotary ripple, and smooth linear force is proposed. The proposed motor combines a five-phase unipolar surface-mounted permanent-magnet

Ergodity of the Motions in the Dynamical Systems with Two Degrees of Freedom [PDF]
International Astronomical Union Colloquium, 1993 AbstractWe study a process of stochastization of the motions in an example of the Henon-Heiles model. We propose a new method to study this process a method of the field of directions of motion in the meridional plane. A numerical integration of the equation for the derivative of this field ∂f/∂n to the normal to a trajectory has been made.

Sensors, 2023 Piezoelectric accurate actuation plays an important role in industrial applications. The intrinsic frequency of previous actuators is invariable. However, variable frequency can approach the range near the low-intrinsic-frequency and realize a high ...
