Musculoskeletal pain is commonly reported by police officers. A potential cause of officer discomfort is a mismatch between vehicle seats and the method used for carrying appointments. Twenty-five police officers rated their discomfort while seated in: (1) a standard police vehicle seat, and (2) a vehicle seat custom-designed for police use. Discomfort was recorded in both seats while wearing p...

The Draper Laboratory Vorticity Control Unmanned Undersea Vehicle (VCUUV) is the first mission-scale, autonomous underwater vehicle that uses vorticity control propulsion and maneuvering. Built as a research platform with which to study the energetics and maneuvering performance of fish-swimming propulsion, the VCUUV is a self-contained free swimming research vehicle which follows the morpholog...

The prime reason for proposing the work is designing and developing a low-cost guided wireless Unmanned Ground Vehicle (UGV) use in hospitals assistance contactless drug delivery COVID-19 wards. Robot designed as per requirements technical specifications required healthcare facility. After detailed survey tests of various mechanisms steering structure UGV, best mechanism preferred articulated b...

This paper describes the design, implementation, and field testing of an infrastructureless system for autonomous tramming (or hauling) of a center-articulated underground mining vehicle. Described is the development of a fast, reliable , and robust " autotramming " technology that does not require the installation of fixed infrastructure throughout the mine.

This paper concerns the design, construction and instrumenting of a six wheel drive, articulated mobile robot capable of very rough terrain navigation. Navigation strategies current and in development, are also presented. Video clips of the vehicle in operation will be presented at the conference.

This paper presents an integrated controller for autonomous articulated electric vehicle (AAEV) path tracking and rollover prevention. The AAEV is vulnerable to due the characteristics of frame steering (AFS) mechanism, which shows improved maneuverability agility but not front wheel steering. In addition, ratio between height track width high, so prone rolling over. Therefore, proposed was des...

an elliptical tank cross-section is formulated to explore and optimization method, based on a real-coded genetic algorithm to enhance the roll stability limit of a tank vehicle. a shape genetic algorithm optimization problem is applied to minimize the overturning moment imposed on the vehicle due to c.g. height of the liquid load, and lateral acceleration and cargo load shift . the minimization...
