Special Issue Information

Dear Colleagues,

It is our great honor to organize this Special Issue of Machines, which is an outstanding academic journal focused on Mechanical Engineering and Science.

Mechanisms and robots play increasingly important roles in numerous areas, such as industry, agriculture, and medical treatment. This Special Issue aims to publish high-quality papers investigating the kinematic and dynamic problems of robotic mechanisms. It calls for papers to discuss ideas on the innovation, design, and application of various mechanisms and robots. Potential contributions may include, but are not limited to, the following topics:

  • Parallel and hybrid mechanisms;
  • Metamorphic mechanisms;
  • Deployable mechanisms and origami;
  • Compliant mechanisms;
  • Robotic systems in machining, manufacturing, and mining;
  • Mobile robots, field robots, and agricultural robots.

Your consideration will be appreciated. We look forward to receiving your submissions and will arrange a timely review.

Yours sincerely,

Dr. Shuofei Yang
Guest Editor

Traditional industrial robots offer significant operational flexibility and adapt well to reconfigurable production systems, although they face limitations in applications demanding high motion performance and spatial positional accuracy. While novel manufacturing solutions supporting small batch productions of custom products are widely researched, they are not yet fully available at industrial level. With the aim to advance in this domain, the present work, conducted in the context of the EU project OPeraTIC, reports the development of a novel manipulator for advanced three-dimensional laser surface treatment of large industrial components. The proposed robotic platform presents a decoupled kinematic architecture, with direct drive actuation in all axes. Its open control ensures adaptability to diverse manufacturing scenarios, making it a versatile tool for modern production lines. Starting from the description of its embodiment design and mechanical layout, the paper delves into robot virtual prototyping focusing on kinematic and dynamics aspects. In particular, a detailed behavioral model covering direct and inverse kinematic calculations, also allowing the precise evaluation of all actuation forces/torques, has been developed using analytical approaches. The model is validated with a commercial solver imposing different spatial motions. The generated performance maps illustrate the robot operational capabilities across a range of work scenarios.

The subject of this paper is the formulation of a general algorithm that is aimed to obtain and analyze the first- and second-order centrodes of both coupler links of Stephenson III six-bar mechanisms, along with the corresponding pairs of Bresse’s circles. The position vectors of both pairs of instantaneous centers of rotation and acceleration centers are expressed as vector functions of the driving input angle of the mechanism and apply the fundamental theorems for velocities and accelerations, respectively. Thus, the proposed algorithm has been formulated by using vector algebra and validated through significant numerical and graphical results by devoting particular attention to the cases in which the second coupler link shows an instantaneous stop configuration, along with those where the first four-bar linkage reaches an asymptotic configuration. These results can be useful for designing and analyzing specific mechanisms for practical applications, such as composing the jaw-crusher machine, which has been selected as an example. Full article

Kinematics is a hot topic in robotic research, serving as a foundational step in the synthesis and analysis of robots. Forward kinematics and inverse kinematics are the prerequisite and foundation for motion control, trajectory planning, dynamic simulation, and precision guarantee of robotic manipulators. Both of them depend on the displacement models. Compared with the previous work, finite screw is proven to be the simplest and nonredundant mathematical tool for displacement description. Thus, it is used for displacement modelling of serial robots in this paper. Firstly, a finite-screw-based method for formulating displacement model is proposed, which is applicable for any serial robot. Secondly, the procedures for forward and inverse kinematics by solving the formulated displacement equation are discussed. Then, two typical serial robots with three translations and two rotations are taken as examples to illustrate the proposed method. Finally, through Matlab simulation, the obtained analytical expressions of kinematics are verified. The main contribution of the proposed method is that finite-screw-based displacement model is highly related with instantaneous-screw-based kinematic and dynamic models, providing an integrated modelling and analysis methodology for robotic mechanisms.
