For the accurate haptic feedback generation and rendering purpose, a detailed computer-aided design model of the switch was developed together with a multibody simulation. Most commercial haptic interfaces are designed to be used as desktop systems with stereoscopic or monoscopic displays. In the second part of the paper, the applications developed are presented for the various fields of engineering and architectural design tasks: design, simulation, virtual testing, virtual navigation, manufacturing and Augmented Reality. This paper describes a new methodology for teaching mechanisms at mechanical engineering courses based on Virtual Reality technology. In laboratory conditions, using a motion capturing system, these behaviors were reproduced, measured and analyzed. For this purpose, in the most recent decade, 3D computer simulations have become common tools used within industry.

The second tool facilitates the design modification in virtual environments system by providing real time dynamic simulation. According to the proposed method, the cam profile is determined as a finite series of points and takes into consideration all contact forces between the cam and the follower, including friction. The associated mechanical model for each category of mobility criteria allows a qualitative assessment of the kinematic and dynamic sets of equations to be formulated in later stages of analysis. Several issues were investigated regarding how the gaze fixation point of the driver is moving during obstacle avoidance maneuvers. This is often illustrated within this book by similar methodologies used for different goals, e.

To achieve this goal, we needed to design and to implement a new framework, which is able to teach an humanoid robot via user demonstration and to imitate movements of the human body. Using the developed haptic system, different setups and designs of the steering system can be naturally tested on the haptic system, and therefore the transmissibility of the system can be easily estimated. The use of such interactive visualisation offers the engineer more realistic real-time representations of the design and advanced facilities to interact with the model during the design process. Such profiles are used for identifying obstacles within the environment and optimum propagation pathways. Aspects related to eco-design, aesthetic style, human factors and ergonomics are now critical issues for the success of a product on the market. The invention relates to a haptic system meant to simulate the kinematic and dynamic operating conditions in the field of articulated mechanisms. In order to illustrate the concept, several experiments have been carried out for the case of specific subsystems of a car, which are partic-ularly involved in the driver—car interaction: steering sys-tem, clutch pedal and the gearshift.

In order to fine-tune the force input and the function performed by the mechanism, the cam profile is normally subjected to a detailed synthesis having as input the desired user force profile. From a main menu the user is able to select a mask that will reveal a second menu with supplementary commands. For various applications, which involve grasping of complex objects, a special haptic device is needed. This is often illustrated within this book by similar methodologies used for different goals, e. These correlations have an important role in the configuration of a virtual simulator used to train basketball free throws.

They have a similar appearance with human body. Aspects related to eco-design, aesthetic style, human factors and ergonomics are now critical issues for the success of a product on the market. Aspects regarding Bluetooth technology, architecture and components of the mobile robot developed are presented. An emerging solution to this challenge seems to be the integration of Virtual Reality technologies into these applications. Thus the meaningful features of an humanoid robots are: the capability to imitate the user behavior, and the ability to learn new skills. The paper demonstrates with a user experiment, how numerical results of computer simulations, which may be difficult to interpret, can be presented using a one degree of freedom haptic device, aiding natural interpretation of the results. The users are asked to complete a simple task such as pour water into a glass from a bottle by activating the manipulation command.

The used software, hardware and methodology are described in detail, as well as the results. This paper aims to present an overview of the multi-body formulations as well as a new formulation based on a model in which the mechanism is regarded as a collection of particles rather than bodies. This paper proposes a novel approach to the virtual prototyping of the steering system, using a dedicated haptic interface, bringing the end product closer to the customer needs. For this reason, haptic devices are becoming more and more sophisticated from the mechanical viewpoint in order to fulfill the wide range of requirements in applications: low inertia, high stiffness, low friction, back-drivability, nearzero backlash, gravitational counter-balancing, sizeable workspace, multiple degrees-of-freedom, and human matched force capabilities. A relatively new research direction in mobile robotics concerns the communication technology for the control mobile robots in conjunction with other devices or between a team of mobile robots.

Therefore, the movements of the human body are automatically tracked using the Kinect sensor, and they teleoperate a whole body of a Nao robot. Product Engineering: Tools and Methods Based on Virtual Reality. For special applications, the design of the belt drives components can be optimised by simulating the drive tests under different loading. Wireless communications in industrial environments are seriously affected by reliability and performance issues, due to the multipath nature of obstacles within such environments. Out of this, haptic devices serve also for input purposes such as tracking of contact point position.

A category of persons that require special attention is represented by the disabled people. . Therefore, the mechanical system used for the experiments is composed of one or more real and virtual elements and joints for example a crank linked to a torque controlled electrical motor. Because no real force feed-back is provided, the user can decide upon the correctness of the grasping posture only from visual feedback. A comparative study is provided, in which the mechanism mobility calculation and interpretation is presented in each case as well as a simulation case study for which the main formulations have been tested. The first mechanism controls the motion of the virtual hand and grasping forces based on the principles of kinematics and energy transfer by contact simulation.
