This paper describes the development of a vision-only intelligent interface for dexterous robots capable of tracking operator motions, analyzing trajectory feasibility, and providf6g visual feedback to the operator. This system analyse3Jhe operator’s arm motion for safety, and then converts at into trajectory commands for a mechanical arm. Potentially dangerous situations, such as singularity a...

The research team at ERAU and UTHSCSA analyzed the effects of suborbital flight stressors various light conditions (red, white, no light) on Arthrospira platensis (Spirulina), onboard Blue Origin’s New Shepard vehicle. Commercially available cyanobacterium species were cultivated closely monitored in mother colonies several months before mission. aim this study was to estimate biomass productio...

The synthesis of the stereospecifically fluorinated difluoro- and trifluoro- rac-3 and rac-4 is described where the fluorine atoms are positioned adjacent/vicinal to each other and the physical characteristics of these candidate liquid crystals including negative dielectric anisotropy are measured and rationalised.

A method for force-free control is proposed to realize pull-out work by an industrial articulated robot arm. This method achieves not only non-gravity and non-friction motion of an articulated robot arm according to an exerted force but also reflects no change in the structure of the servo controller. Ideal performance of a pull-out work by the force-free control method was assured by means of ...

In this paper, we use a calculation path technique based on the configuration space in the case of an articulated robot of two degrees of freedom. We propose the use of artificial potential fields to represent the configuration space and the use of techniques of artificial intelligence like A* and D* to search a free collision path into the configuration space. This combination of techniques ca...

Most visitors experience national parks using their personal automobiles, but what is the capacity of park roads to accommodate this use? A simulation model of a national park scenic road was built to explore the road’s social carrying capacity and service quality. Current and potential future vehicle use levels were compared in the simulation against visitor-reported standards for congestion. ...

This paper focuses on the trajectory planning and tracking control of articulated tracked vehicles (ATVs). It utilizes path method based Hybrid A-star minimum snap smoothing to obtain feasible kinematic trajectory. To overcome highly non-linearity ATVs, we proposed a linear-parameter-varying (LPV) tracking-error model. Then, controller was formulated as adaptive model predictive (AMPC). The sim...

The article presents a framework for the resolution of rich vehicle routing problems which are difficult to address with standard optimization techniques. We use local search on the basis on variable neighborhood search for the construction of the solutions, but embed the techniques in a flexible framework that allows the consideration of complex side constraints of the problem such as time win...
