Opis:
The paper presents the method for the optimal synthesis of four-link mechanism generating open/closed paths with time prescription. Although the method is suitable for both closed and open paths, it enables decreasing the number of design parameters describing dimensions, orientation and position of a path generator. Compared to the methods presented in the references, this is a one-phase synthesis method; although the number of design parameters is reduced, the method does not require affine transformations to be performed on the synthesised mechanism. The effectiveness of the method is discussed based on examples of three paths, with two taken from the literature.

Opis:
A technique for path synthesis is employed to design a feeder for carrying products between two points. The feeder is assumed to be a one degree of freedom system of six links connected by means of revolute joints. The mathematical basis of the concept is presented. An exemplary solution is presented and discussed.

Opis:
The paper is dedicated to the kinematic synthesis of dwell linkage mechanisms on the basis of the four-bar linkage. As known, to obtain the dwell of the output link, linkage mechanisms can be used and they have a number of advantages in comparison with other types of mechanisms. Using the kinematic geometry methods, special points of the mechanism’s coupler plane can be found. One of these points is Burmester point and it enables to synthesize four-bar linkages which coupler point traces the curve, a part of which is approximately close to the arc of the circle. By joining the additional structural group, dwell linkage mechanism can be designed. But the problem is to find such parameters of the mechanism which allow designing dwell linkages with a given duration of the dwell. Using the presented numerical and analytical method, this problem was solved; the samples of reference diagrams for the synthesis are also presented in the article. The method enables to carry out kinematic synthesis of dwell mechanisms, taking into account a number of other parameters, such as the length of the links, maximum displacement of the output link, dwell exactitude etc.

Opis:
The article addresses the three-dimensional (3D) underwater path planning problem of an autonomous underwater vehicle (AUV) in a time-varying current. A modified artificial potential field algorithm combining the velocity vector synthesis method is proposed to search for the optimal path. The modified potential field (MPF) algorithm is designed to dynamically plan the non-collision path. Meanwhile, this modified method is also proved to be an effective solution to the goals not reachable with obstacles nearby (GNRON), U-shaped trap, and rotation unreachable problems. To offset the influence of time-varying current, the velocity synthesis approach is designed to adjust the AUV movement direction. Besides, considering path planning in the complex underwater environment, the multi-beam forward-looking sonar (FLS) model is used. Finally, simulation studies substantiate that the designed algorithm can implement the AUV path planning effectively and successfully in a 3D underwater environment.
