In human–robot collaboration (HRC), human motion capture can be considered an enabler for switching autonomy between humans and robots to create efficient and safe operations. For this purpose, wearable motion tracking systems such as IMU and lighthouse-based systems have been used to transfer human joint motions into robot controller models. Due t...
Chapter
In virtual production planning, simulating human motions helps to improve process planning and interaction efficiency. However, simulating multiple humans sharing tasks in a shared workplace requires understanding how human workers interact and share autonomy. In this regard, an Inertial Measurement Unit based motion capture is employed for underst...
Chapter
Today, increased demands for personalized products are making human-robot collaborative tasks a focus of research mainly for improving production cycle time, precision, and accuracy. It is also required to simplify how human-robot tasks and motions are generated. A graphical flow control-based programming can be one of such methods. This work inves...
Chapter
Flexible and varied manual assembly processes in the automotive industry are often based on manual labor. While simulation can be used to improve planning to maximize efficiency while minimizing ergonomic issues for workers, common simulation tools require extensive modeling time. In such simulations, the users are often process engineers who want...
Article
Collaborative assembly operation is one of the current challenges regarding human robot collaboration (HRC). In this context, it is still unclear how robots and humans should behave in handling an object and anticipating mutual care. In many cases, the modeling of collaborative behaviors shows difficulties, which can be addressed by simplifying mot...
Conference Paper
Semantic representation of motions in a human-robot collaborative environment is essential for agile design and development of digital twins (DT) towards ensuring efficient collaboration between humans and robots in hybrid work systems, e.g., in assembly operations. Dividing activities into actions helps to further conceptualize motion models for p...

Due to the change from mass production to mass personalized production and the resulting intrinsic product flexibility, the automotive industry, among others, is looking for cost-efficient and resource-saving production methods to combining global just-in-time production. In addition to geometric manufacturing flexibility, additive manufacturing of...
Article
In der Planung von teilautomatisierten Montageprozessen ist ein wichtiges Ziel, nicht wertschöpfende Tätigkeiten wie Laufbewegungen zu vermeiden. Studien haben gezeigt, dass die tatsächlichen Laufbewegungen in Montageprozessen von den geplanten Bewegungen abweichen. Dieser Beitrag stellt eine Methode vor, tatsächliche Laufbewegungen mit Motion Capt...
Article
Simulating human motion behavior in assembly operations helps to create efficient collaboration plans for humans and robots. However, identifying human intention may require high quality human motion capture data in order to discriminate micro-actions and human attention. In this regard, a human motion capture setup that combines various systems su...
Article
Assembly operation simulation can e.g. be used for optimizing complex manual assembly processes in the automotive industry. However, realistic human motion modeling involves difficult tasks such as inserting objects that require constraint definitions and collision detection. In this work, a method that applies the concept of an optimized potential...

Human-robot collaboration is combining the extended capabilities of humans and robots to create a more inclusive and human-centered production system in the future. However, human safety is the primary concern for manufacturing industries. Therefore, real-time motion tracking is necessary to identify if the human worker body parts enter the restric...
Article
Full-text available
Tool-path, feed-rate, and depth-of-cut of a tool determine the machining time, tool wear, power consumption, and realization costs. Before the commissioning and production, a preliminary phase of failure-mode identification and effect analysis allows for selecting the optimal machining parameters for cutting, which, in turn, reduces machinery fault...

Many manmade machines and mechanisms including robots function based on the concept of nature-inspired design so that they can perform their intended duties by mimicking the working mechanisms of animals and insects. Accordingly, walking machines (robots) use wheels and tracks to cross rough terrain efficiently and in a stable way than more convent...
Conference Paper
Abstract---Today, there is almost no production process where either machine or product motion is obsolete. This motion can be abstracted from primitive features such as prismatic and revolute joint actuators. Industrial robots implement any of these motion primitives to manipulate in a defined space configuration. However, in both simulation an...

Multi axis machine tools implement real time motion control algorithms. Objects including difficult to manufacture and deformable shapes show variable properties when tools apply a pressure on the object surface. Force compliant industrial robots are used to manipulate deformable objects in real time simulation. In this research, a hierarchical met...

Pantograph arc is one of the most common and yet unavoidable difficulties in electrified railways. During winter the intensity of arcing increases due to ice layer on the overhead catenary wire. In AC traction system, the sinusoidal waveforms of the supply voltage and current distort due to pantograph arcing. It generates both conducted and radiate...
