As a basis for this effort, the robotic arm's performance capabilities (dexterity, repeatability, etc.) need to be assessed before an appropriate configuration is chosen. The availability of modern computing tools can simplify this process. The objective of this

A total of 13 loads of silage crops were harvested during tests in commercial silage fields. The masses of the empty and full silage wagon were measured with a platform scale before and after

Heavy reliance on agricultural chemicals and low fertilizer use efficiencies in citrus production have raised environmental and economic concerns. In this study, a nitrogen sensor was developed to predict nitrogen concentrations in orange leaves. Four design criteria were chosen to maximize the sensing efficiency and reliability.

General equations are derived from which the instant depth of cut in ball end milling can be calculated. Examples are given for four path increment modes. The cutting condition in

ABSTRACT The permanent mapping of soil or crop variability or the control of field operations in ... more ABSTRACT The permanent mapping of soil or crop variability or the control of field operations in response to previously measured variabilities requires a method of absolute position determination. This article reports on research on the testing and use of a nautical microwave distance measuring unit for agricultural field location. It was found to be successful for providing the path plot of a combine. A theory and methodology for the optimum locations of repeater remotes for triangulation equipment was developed and demonstrated. The theory minimized the maximum fix error in a two-dimensional field by indicating proper placement of the remotes.

These technologies will require engineers to work at a minute level such as atomic or molecular. Currently, we use technologies such as transient finite element analysis, system control and simulation dynamic mass modelling, three-dimensional design and assembly. In the next 10 years, we will be solving problems and doing research in biosensors, biomaterials, bioelectronics, inert materials, magnetic materials, and fluorescent materials, which will require the expertise of multi-disciplinary teams of scientists and engineers. Specifics on these areas are presented to enhance our profession's involvement in the future. The engineering environment in the future is also discussed.
