The TwinCAT Supplement ‘TwinCAT Kinematic Transformation’ is presented in this application example. This supplement makes it possible to compute robot kinematics together with the PLC and Motion Control on one PC-based CPU. Analogous to the TwinCAT Motion Control package (integration of the drive control in the controller), a robot kinematics is configured and parameterised with the ‘Kinematic ...

This paper introduced design analysis of a new 5DOF surgical robot used for minimally invasive surgery. The kinematics modeling is studied by solving the forward and inverse kinematics of the robot using the Denavit-Hartenberg convention and geometrical method. Robot kinematics simulation is built by creating the 3D CAD model of the robot and patient, then a kinematic motion simulation of a sur...

Background. This study aims to analyze the movement of backhand and forehand smash stroke techniques in badminton in three dimensions using a kinematics approach. Objectives. The obtained results were analyzed using a descriptive and quantitative approach. Methods. Furthermore, 24 male badminton players from the university student activity unit with an average age of 19.4 ± 1.6 years, height ...

Objectives: Children aged 10 to 12 years often show dangerous maneuvers during landing, which include increased knee valgus, placing them at higher risk of anterior cruciate ligament (ACL) injuries. The study aimed to investigate the relation of the trunk and hip kinematics with the peak knee abduction angle during single-leg landing among preadolescent female soccer players. Methods: Thirty-s...

Binary manipulators are powered by actuators which have only two stable states. Therefore, they can reach only a discrete (but possibly large) number of locations. Compared to a manipulator built with continuous actuators, a binary manipulator provides reasonable performance, and is relatively inexpensive (up to an order of magnitude cheaper). The number of states of a binary manipulator grows ...

In this paper, we study the existence of solution of the four-point boundary value problem for second-order differential equations with impulses by using leray-Schauder theory: ⎧⎨ ⎩ x′′(t) = f(t, x(t), x′(t)), t ∈ [0, 1], t = tk, k = 1, 2,··· ,m Δx(tk) = Ik(x(tk)), k = 1, 2,··· ,m Δx′(tk) = Ik(x(tk), x ′(tk)), k = 1, 2,··· ,m x′(0) = αx′(ξ), x(1) = βx(η), (E) where 0 < ξ ≤ η < 1, α ≥ 0, β ≥ 0 a...

The shift to modularized cars leads to the need for early and precise concept decisions for the development of modules. Many module definitions focus on the interaction between modules to make them upgradeable. The focus here is on modules that have to work with unknown restrictions in terms of uncertainty. In this paper, emphasis is put on unknown car styling in early design stages. Because of...
