In the scope of this work, a frequently used gaming device-the gamepad-is investigated as a control device for industrial robots in order to extract new ideas for the improvement of existing control devices. Thus, an approach for the integration of a gamepad control in a common industrial robot system is developed and implemented. The usability of the gamepad control is improved by adding a smartphone to the gamepad, which serves as a display to show information to the user. Finally, the developed gamepad control is compared with the operation via conventional control device.

This work is concerned with the existence of asymptotically stable 2-D (2-dimensional) systems by means of a feedback control model represented by the system of partial difference equations and their Lagrange solutions. Thus, the goal is to establish a controller that provides a feedback control system with state variables depending solely on its Lagrange solution in the sense that the solution to the variable state is not a linear combination of other Lagrange solutions. Roughly speaking, the results showed that, to achieve such a control system, the controller has to diagonalize the block matrices of the matrices composing the system description model. Finally, a numerical example is presented to show how the controller is designed in order to generate a stable feedback control with given Lagrange solutions.

The L-2-gain computation of a linear time-invariant system with state and input delay is discussed. The input and the state delay are handled separately by using dissipation inequality involving a Lyapunov-Krasovskii functional and integral quadratic constraints. A conic combination of IQCs is proposed for characterizing the input delay, where the coefficients are linear time-invariant systems. The numerical example (a vehicle platoon) confirm that using this dissipativity approach a more effective method for L-2-gain computation is obtained.

This paper deals with the passenger ride comfort of electric vehicle. A generation method of speed pattern is proposed for improving the ride comfort against the longitudinal acceleration/deceleration. The speed pattern generated using proposed technique is based on the general optimal control theory with evaluating the acceleration and the jerk which is time derivative of the acceleration. The effectiveness of the present method is demonstrated through numerical experiments.

The paper focuses on a recently introduced paradigm for the logistic process of picking, with respect to the man-to-goods and goods-to-man concept: the robot-to-goods. First the task and system architecture of the fast deployable autonomous commissioning system are described, then the economic efficiency of the system is analysed in a real business case scenario using a simplified method, which is explained and discussed. The clearly positive Net Present Value of the investment and the short Payback Period obtained in the business case prove how the robot-to-goods paradigm for the commissioning process, implemented through the automation of the forklift platform, is economically attractive for small and medium size enterprises.

Today's factory floors are a distributed system of heterogeneous components. They exist a high degree of production customization to cater for this most factory floor systems are being adapted for customization. Most current manufacturing communication systems do not have a flexible architecture to serve the changeable and dynamic market needs thus presenting a research gap in flexible communication. This paper discusses a middleware communication system that allows for flexible optimal control of information flow in a fixture based production system. The architecture of the system aims to integrate seamlessly a heterogeneous factory environment, for autonomous monitoring and control of information on the factory floor.

This paper presents experimental results obtained using a friction-based slippage and tangential force sensing device that has been developed for the purpose of reliable object slippage prevention during robotic manipulation. The experimental results obtained demonstrate that the developed slippage sensing strategy is rugged and reliable even in its current "rough prototype" state of development. This work has the potential to yield a low cost and highly customisable slippage and tangential force sensing device for a variety of robotic object grasping and manipulation applications. It is envisaged that the work presented here will be beneficial to researchers in the area of object slippage prevention.

The diffusion furnace is an important and indispensable equipment in the production process of solar cell, it plays a crucial role in the photoelectric conversion efficiency of the solar cell. Production efficiency and temperature control precision of traditional closed diffusion furnace is low. To solve this problem, this paper presents a temperature control system of continuous diffusion furnace. The system uses PID cascade control algorithm based on Smith estimating pre-compensation to achieve the temperature control of furnace and ensure the uniformity and stability of the temperature, so as to ensure the uniformity of the dopant diffusion. The simulation results verify the effectiveness of the control algorithm;and practical experiments prove the feasibility of the temperature control system.

The paper is aimed to the robust control of parametric uncertain linear plants in conditions of signal quantization with time delay and bounded external perturbations. State vector of control plant is unmeasured. Output of control plant is measured only via quantizer with transport delay. control algorithm is based on consecutive compensator method. Proposed algorithm provides convergence of tracking error to the reference signal with prespecified accuracy for bounded time delay in quantizer. Limitations on value of delay providing stability of closed-loop system are obtained.

Small sized robotic systems have operational advantages compared to large systems. They can also operate in fields of application where bigger systems would fail. This paper describes the specifications and the design of the autonomous underwater vehicle mu AUV(2). Technical details of the system regarding sensor setup, motorization and computing power are given. Furthermore, we present details about the system identification process and the implemented controller structure. Possible scopes of the mu AUV(2) are underwater exploration, inspection tasks, development and evaluation of algorithms, education and competitions.
