In view of the safety and medical concerns of patients and the persons delivering medicines on a timely fashion, robotic delivery of medicines in wards of hospitals using artificial intelligence techniques is investigated in this work. The robot traverses the wards where the medicine needs to be delivered using intelligence-based algorithm based on sensors and indicator marked in the wards, in the best possible shortest path and exits the ward. The program would ensure that the robot does not collide with other robots and humans in the path and also would search for the indicator where the medicine would have to be delivered on a timely fashion. This way, we would ensure that contagious diseases are not transferred when medicine delivery is done and also compared to the same with laborious process being done manually. This proposed method functionality and algorithm is tested on a prototype arena and was proven to be successful using a firebird V robot in the laboratory for the algorithm. The proposed method saves time and also human resources and is easy to operate with external monitoring from the hospital reception.

A novel fuzzy preview controller based on look up tables is proposed for control design of a rotary inverted pendulum represented with integrated time delay in system matrices. The proposed control achieved control of all system states with predefined standard requirements. The advantage of preview control helps in conservation of energy as the control input acts upon after a lookup making the system robust even under the impact of custom designed system time delays that were incorporated into the system. The proposed method shows the influence of time delay can be countered effectively by integrating the delay into the system matrix and then using the novel fuzzy granular preview control.

A series RLC circuit in network analysis is analyzed as a standalone circuit and then as a rectifier circuit with unexpected time delays integrated into system matrix. The paper focuses on the effect of time delay and how time delays would make the system ill-conditioned from well conditioned matrix when a row and column gets appended to the matrix due to integration of time delay into the system definition and is under the purview of a fuzzy controller. The system definition by augmentation yields a new matrix and the slight variations in time delay drastically effect the performance of circuit as observed resulting in the circuit to behave with less bounds on control due to formulation of ill conditioned matrices. The performance of the rectifier circuit improves with the fuzzy controller embedded into the system.

Flower pollination is a single objective optimization technique which as a unconstrained optimization method is applied for the stabilization of the rotary inverted pendulum system. It was observed that the flower pollination method gave better sensitivity in control of the pendulum about its upright unstable equilibrium position with less time and definitely indicated that the method is an energy efficient method when compared with other methods like direct pole placement. This method yielded results under the influence of time delay and have proven that the influence of time delay is significantly felt and would cause loss of energy, however the presence of flower pollination for optimization minimizes the loss incurred due to time delay and makes the system significant in terms of sensitivity.

Actuators and Manipulators either robotic or mechatronic require controllers which are very accurate and fast. The rotary inverted pendulum has been an under actuated system classified as a potential model in the category of advanced research problems. In this paper, a method is proposed for stabilization of a rotary inverted pendulum using full state feedback controller based modified particle swarm optimization with constraints on settling time, peak time and peak overshoot. The method paves way to advanced signal processing techniques for design and control of complex dynamic systems.
