Kinematic synthesis of a trailing six-member mechanism has been carried out to achieve five precision points of an automotive steering mechanism. The inner wheel can be rotated up to forty five degrees with fair accuracy. Results show that the divergent end behavior of Ackermann Steering Mechanism has been overcome by the present mechanism. The work is similar to earlier work by the present ...

This paper discuses sensor steering mechanism (SSM) for a laterally guided vehicle with a rear wheel steering mechanism. The authors have demonstrated the geometry of SSMs for front wheel steering type and reverse phase four-wheel steering type vehicles. SSMs allow stable lateral guiding performance for automated vehicles following a path with straight and curved portions created by a guideway....

We present results of parallel molecular dynamics simulations of nanoindentation and nanotribology experiments. The models we have developed describe both the sample and the indenter atomistically and model the effect of the cantilevers in an atomic force microscope through the use of springs. We show that the simulations are in good qualitative agreement with experiment and help to elucidate m...

We show that optomechanical systems in the quantum regime can be used to demonstrate EPR-type quantum entanglement between the optical field and the mechanical oscillator, via quantum-state steering. Namely, the conditional quantum state of the mechanical oscillator can be steered into different quantum states depending the choice made on which quadrature of the out-going field is to be measure...

Small hair-like cell protrusions, called filopodia, often establish adhesive contacts with the cellular surroundings with a subsequent build up of retraction force. This process seems to be important for cell migration, embryonic development, wound healing, and pathogenic infection pathways. We have shown that filopodial tips are able to sense adhesive contact and, as a consequence, locally red...

The existing colonoscope requires a dexterous skill of surgeon to perform the insertion in entire colon. The procedure is painful to the patient. Therefore, biomedical and robotic researchers are developing a locomotive colonoscope that can travel safely in colon In this paper, we describe a new design and concept of semi-autonomous micro robot for colonoscopy. The micro robot comprises the act...

Computational steering is the online, interactive allocation of resources and adjustment of application parameters. Although several systems for steering distributed computations have been developed, few support the coordinated steering of multiple processes. Of those that do provide such support, most take a conservative approach. Our system is unique in its optimistic approach. Coordinated st...

As computer vision based systems like lane tracking, face tracking and obstacle detection mature an enhanced range of driver assistance systems are becoming feasible. This paper introduces a list of core competencies required for a driver assistance system, the issue of building in robustness is highlighted in contrast to leaving such considerations to a later product development phase. We then...

An actuator design for beam steering micromirrors is reported. Coarse positioning is achieved with a 4-bit mechanical digital to analog converter [1]. The exact position is sensed by a set of lateral comb fingers and controlled through the leastsignificant bit of the DAC, which is embedded in a feedback loop. The actuator is designed for bilateral actuation of +/3μm with a resolution of 6nm pro...
