“…It was observed that small changes in shape, the use of full collision detection and the use of stereo-view, can affect assembly times in haptic virtual assembly environments. Similar results were obtained by Garbaya and Zaldivar-Colado (2007), who observed that human operators have better performance when force feedback is provided during assembly tasks.…”

Abstract Purpose -In this study, a new methodology to evaluate the performance of physics simulation engines (PSEs) when used in haptic virtual assembly applications is proposed. This methodology can be used to assess the performance of any physics engine. To prove the feasibility of the proposed methodology, two-third party PSEs -Bullet and PhysXtm -were evaluated. The paper aims to discuss these issues. Design/methodology/approach -Eight assembly tests comprising variable geometric and dynamic complexity were conducted. The strengths and weaknesses of each simulation engine for haptic virtual assembly were identified by measuring different parameters such as task completion time, influence of...

Virtual reality for assembly methods prototyping: a review

Assembly planning and evaluation is an important component of the product design process in which details about how parts of a new product will be put together are formalized. A well designed assembly process should take into account various factors such as optimum assembly time and sequence, tooling and fixture requirements, ergonomics, operator safety, and accessibility, among others. Existing computer-based tools to support virtual assembly either concentrate solely on representation of the geometry of parts and fixtures and evaluation of clearances and tolerances or use simulated human mannequins to approximate human interaction in the assembly process. Virtual reality technology has the potential to support integration of natural human motions into the computer aided assembly planning environment (Ritchie et al. in Proc I MECH E Part B J Eng 213(5): [461][462][463][464][465][466][467][468][469][470][471][472][473][474] 1999). This would allow evaluations of an assembler's ability to manipulate and assemble parts and result in reduced time and cost for product design. This paper provides a review of the research in virtual assembly and categorizes the different approaches. Finally, critical requirements and directions for future research are presented.

“…Recent studies of haptic interfaces have focused on the use of a commercial interface (PHANToM) when used in assembly tasks where a hand-held object is being manipulated (e.g., peg-in-hole task) [7,8,3]. As a first step toward developing a haptic force feedback device for the borescope, we developed a simple OFF/ON haptic device using a cheap off-the-shelf motor kit.…”

A haptic virtual borescope is developed for the purpose of aircraft engine inspection training, similar in spirit to borescope trainers intended for use in gas turbine maintenance training schools. Such devices consist of engine section mockups for use with a real borescope. Our approach instead simulates engine sections in virtual reality, replacing the need for physical mockups. We model the engine casing as a "black box" where a simulated borescope tip is inserted (in practice a real borescope is used to provide tactile veridicality of the probe's braided sheath but the camera at its tip is not used). The probe's translational movement is mapped to the virtual camera's. The graphical engine representation can conceivably generalize to any engine section that can be modeled graphically. Since the interior chamber of the "black box" casing is empty, the critical component of our simulator is correct borescope tip navigation as well as force feedback response based on a mathematical model of collision detection of the tip in the computer generated environment.Haptic response is thought to be a key component of the simulator as it provides non-visual tactile awareness of the borescope tip within the engine under inspection and, more importantly, its contact with engine surfaces. Our contribution is two-fold. First, we design a novel motor-powered clamp that provides collision response to collision of the camera detected in virtual space. Second, we attempt to isolate the effect of the system's tactile response and provide empirical evaluation of its utility. In line with previous results, our empirical analysis reveals a trend toward a benefit in performance (speed), but suggests that the provision of haptic feedback, while preferred over a solely visual interface, may be perceived as extraneous in a visually-dominated discrimination task.
