The word “robot” originated from robota, a Czech word that means forced labor. The majority of robots are used to execute dedicated, complex, risky, and continuous manufacturing jobs. In comparison with humans, robots are able to do repetitive work with higher precision and efficiency. Irrespective of the working time, they perform a repetitive task with the same amount of energy [1–3]. A robotic arm is similar to a human arm [4] and can be programmed. This is a mechanical arm able to perform translational or rotational motions in a controlled environment [4–6]. The various links of an arm are connected by joints. Robotic arms are available in a large number of variants. These arms are usually designed for specific tasks to work in varied environments. The automation by robotic arms results in reduction of errors in repetitive jobs [7, 8].
Digital twin and virtual reality: a co-simulation environment for design and assessment of industrial workstations

Virtual reality allows also validating the robotic arm behaviour with a real operator involved in the scene. As human and robot shared tasks and workspace, it is mandatory to safely test and check that the robotic arm will not collide with any part of the workstation or hurt the operator (see Figure 9). What is fundamentally different between virtual reality and simulation through digital twin is that, in virtual reality, the operators are real persons acting and taking risks, as they would do on the real workstation. As an example in Figure 9, the same operator has performed several times the same assembly task inside the virtual reality environment. With the habits, the operator has approached the robotic arm and it has collided with him. When a collision occurs, the virtual reality engine detects it and can report it, by putting the robotic arm in red (see (b) in Figure 9). In such a case, the configuration of the manual station or the program of the robotic arm must be reconsidered.

A great advantage of robotic equipment in production lines is that of a robot arm being able to undertake different processes by only having its tools changed (Ljien 2016). For example, a robot may be equipped with a welding gun during the welding process and then replace it with a gripper to be used in a handling process. Except for the replacement of the tools, robots can exchange tools between them in a cooperation environment. Therefore, the production line becomes more flexible and efficient (Michalos, Makris, and Chryssolouris 2015). In addition, the number of required tools may be reduced as they are shared by the robots. In principle, there are several research works which deal with the robotic grasping applications in production processes (Fantoni et al. 2014).

The expression robotic is basically defined as the paper, strategy and usage of robotic systems for industrial (ISO 8973, 1994). Robotics is usually employed to achieve hazardous, very repetitive, unsafe and unkind jobs. They have several different jobs such as arc welding, assemblage, material handling, spraying, painting, and machine load and unload function, etc. Robotic arm is planned to move material, parts, or particular devices through variable programmed motions to perform a variability of jobs (Elfasaikhany, Baylon, Salgado, & Yanez, 2011).
