New research on Robotics is the subjec t of a report. According to news originating from Suva, Fiji, by NewsRx editors, the research stated, "Adaptation to technological advancements and intelligent digital tools can enable healthcare providers to overcome the challenges of thei r patient-oriented care systems and processes. One such intelligent tool is auto mated assistive robots, which can improve patient care and safety in the health sector." Our news journalists obtained a quote from the research from the University of t he South Pacific, "This paper presents an invariant set of continuous nonlinear control laws for an assistive robot and a rehabilitation wheelchair robot modele d as a new autonomous robotic dog and rehabilitation wheelchair system for navig ating a highly constrained environment. The control laws are derived from the Ly apunov-based control scheme classified under the umbrella of artificial potentia l field (APF) methods, and inherently proved stability of the new heterogeneous system. The robotic dog guides the wheelchair robot during the navigation proces s in a cluttered environment where the avoidances are from the robotic dog and t he integrated dynamic protective polygon. The wheelchair traverses the obstacle- free path traced by the dynamic polygon. The leash is flexible, and its length i s bounded, which invariably provides the protective polygon to change its intrin sic dimension. Thus, the dual-robot system has increased mobility for obstacle a voidance and passing through narrow passageways. The solution proffered herein i s only feasible in a highly constrained and isolated human environment where not hing else appears to be moving in the direction of the robotic dog and wheelchai r. The computer simulations and associated convergence graphs present the effica cy of the unique control laws for the new heterogeneous robotic system."
