“…Part assembly is accomplished by "snapping" a part to its final position when two parts come within close proximity. One of the first applications that integrated positional constraint based modeling was VADE (Virtual Assembly Design Environment), developed in 1995 by Jayaram et al [22][23][24][25][26][27] (Fig. 4).…”

Experience with current Virtual Reality (VR) systems that simulate low clearance assembly operations with haptic feedback indicate that such systems are highly desirable tools in the evaluation of preliminary designs, as well as virtual training and maintenance processes. The purpose of this research is to develop methods to support manual low clearance assembly using haptic (force) feedback in a virtual environment. The results of this research will be used in an engineering framework for assembly simulation, training, and maintenance. The proposed method combines voxel-based collision detection and boundary representation to support both force feedback and constraint recognition. The key to this approach is developing the data structure and logic needed to seamlessly move between the two representations while supporting smooth haptic feedback. Collision forces and constraint-guided forces are blended to provide support for low clearance haptic assembly. This paper describes the development of the method.

“…Interaction forces can be calculated in two ways: a) local force rendering mode-forces are computed locally by the haptic-control interface based on its parametric model, and b) external force rendering mode-forces are computed by the host PC and sent to the control interface to be displayed by the glove. The general force model is (8) where is a displacement proportional to the penetration distance of the virtual fingertips into a virtual object. The model parameters are: stiffness , viscosity , and offset force .…”

“…Such simulations are those for CAD/CAM design [8], multiplexed telerobotics [9], hand rehabilitation [14], etc. Force-feedback gloves need to provide sustained forces to multiple fingers, should be light (to minimize user fatigue), need to be safe, and should preserve the user's natural arm freedom of motion as much as possible.…”

Abstract-The Rutgers Master II-ND glove is a haptic interface designed for dextrous interactions with virtual environments. The glove provides force feedback up to 16 N each to the thumb, index, middle, and ring fingertips. It uses custom pneumatic actuators arranged in a direct-drive configuration in the palm. Unlike commercial haptic gloves, the direct-drive actuators make unnecessary cables and pulleys, resulting in a more compact and lighter structure. The force-feedback structure also serves as position measuring exoskeleton, by integrating noncontact Hall-effect and infrared sensors. The glove is connected to a haptic-control interface that reads its sensors and servos its actuators. The interface has pneumatic servovalves, signal conditioning electronics, A/D/A boards, power supply and an imbedded Pentium PC. This distributed computing assures much faster control bandwidth than would otherwise be possible. Communication with the host PC is done over an RS232 line. Comparative data with the CyberGrasp commercial haptic glove is presented.
