Design, Modeling and Indigenous Firmware of Patient Assistance Flexible Robotic System-Type I: Beta Version

 

Abstract

The ensemble of Assistive Robotics is slowly emerging as the new front-edge research arena due to its wide-spread applications in health care sector. Although exoskeletons are is use to a limited extent in the field of health care, it has its own limitations so far the design, prototyping & miniaturization are concerned. Patient-centric customized health care is the need of the hour and research frontiers are also getting negotiated accordingly. One such promising application manifold of Assistive Robotics is the incorporation of multi-degrees-of-freedom flexible robotic system, equipped with tailor-made mini-gripper(s). In-line with the proposition an indigenous design, modeling and firmware of Patient Assistance Robot (PAR): Type I has been accomplished by us as version 1.0 prototype (Beta version). The characteristics of PAR v1.0 are identical to that of Flexible Robotic System with multiple links & intercepting joints, besides fittment of three different miniaturized grippers. The ensemble programming logic for the robot is developed towards controlling in-built vibration in real-time.

Survey of Results Regarding the Energetic Balance for Some Motions of Newtonian and Non-Newtonian Fluids

Abstract

Exact expressions for dissipation, power of the shear stress at the wall, the energy variation and the boundary layer thickness are provided for three unidirectional motions of Newtonian and non-Newtonian fluids over an infinite plate that moves in its plane or applies a shear stress to the fluid.

A Novel Fuzzy Trajectory Tracking Control Design for Wheeled Mobile Robot

 

Abstract

A novel fuzzy based control design for the trajectory tracking of wheeled mobile robot (WMR) is presented in this paper. This approach can be applied to generate trajectory tracking control commands on WMR movement. The design objective is to specify one fuzzy control law that can force the WMR to track a predefined trajectory for the nonlinear trajectory tracking control of WMR. In general, it is hard to obtain the closed-form solution from this nonlinear trajectory tracking problem, hence we try to treat this trajectory tracking problem from the so-called fuzzy control design concepts. Finally, one testing scenario: circular reference trajectory tracking is applied to performance verification.
