Robot fabrication has always been a costly matter. Even for educational purposes, one will need to spend substantial amount of money for building single robot with limited capabilities. When it comes to development of higher capabilities and intelligence, more investment will be required. In this paper, we present details of a mobile robot that is specially designed and made to be used as a stand-alone...
This research proposes a scheme of area calculation system, focusing on image warping to top view. The sensor attached to camera is used to compensate the camera's orientation in real time. One constraint is that the calculated area is planar surface. In practice, the alignment of sensor and camera is imperfect. This error makes the calculated area size inaccurate. Therefore, calibration between camera...
The Human-Robot Cloud (HRC) is an innovative extension of Cloud Computing across two important directions: First, while traditional cloud computing enables transparent utilization of distributed computational as well as storage resources, the HRC enables, in addition to the above two, the utilization of (a) distributed sensing (sensor network technology) and (b) actuator networks (including robot...
This paper aims to propose an IOT(Internet of Things) gateway with multi-channel of RS485, which ensures the real-time performance and reliability for IOT while transferring data between the application and the underlying layer, improving the organization and management efficiency of endpoint devices and solving the problems of data transmission among different protocols. Based on STM32F107 and VK3224,...
An overhead crane transfers the payloads of various volumes and weights depending on the each operation case. The friction factors characterized by damped coefficients can be changed in connection with operating environment. This study develops an adaptive version of sliding mode controller for the overhead cranes without priori information of cargo mass and damped aspects. The controller simultaneously...
This paper presents estimate analysis on three different applications using minimum phase filter when it is applied with adaptive FIR (finite impulse response) filter in beamforming structure. For a same estimate in filter weights of adaptive FIR filter, it is found that an application using a ratio of two minimum phase filters in one input shows a same result with an application using two inverted...
At present, HD video player becomes more and more important in video area. But only by using CPU, HD video player can't play smoothly because of low computing power. GPU is often used in high performance computing now. Therefore, a new HD video player method based on GPU technology is proposed in this paper. It uses open-source video codec solutions for the VLC and VAAPI hardware acceleration interface...
Car navigation systems, which are a part of technologies of Intelligent Transportation System (ITS), support drivers in driving efficiently by showing the shortest routes and some driving information such as that related to traffic jams and weather reports, that are collected from physical sensors and news media. This paper presents a proposal of a method to extract real-time driving information using...
Wind power predication is significant for the safety and stability of power system operation. Due to the power forecasting single model or combination model without considering the information fusion and the influence of forecasting error on power dispatching, forecasting results are not accurate enough. In the paper, a novel combination model for wind power forecasting with error evaluation parameter...
Microgrids are subsystems of the distribution grid which comprises small generation capacities, storage devices and controllable loads, which can operate either connected or isolated from the utility grid. A microgrid has the ability to increase energy efficiency and reduce emissions. This paper studies the microgrid environmental/economic problem, i.e. the problem of optimizing microgrid operations...
This paper presents an optimization analysis for energy and power management in microgrids with renewable energy resources and diesel generators. Dynamic Programming (DP) algorithm and the simplex method have been used to minimize the total daily cost of the system and also maximize the total efficiency of the energy storage system during charge and discharge. The algorithm is validated on a hybrid...
Wind is being aggressively pursued as a potential source of renewable electric power. However, the principal difficulty when integrating wind power into the utility is one of controls. Regulating a power system to provide balance between source and load is challenging when a significant amount of generation is produced by variable sources. This has sparked a wave of research into the development of...
This paper aims to propose a robust invisible near-infrared (NIR) structured-light 3D sensor to identify the location of the picked-and-placed object for a mobile manipulator. The NIR 3D sensor consists of a gobo commercial projector and two off-the-shelf monochrome camera with NIR pass filter. Taking advantage of the NIR light, the negative influences of both object texture and ambient light are...
The switch reluctance generator is a robust and simple structured machine, which is able of producing relatively high voltages while maintaining high efficiency. These types of machines are gaining considerable attentions in variable speed generation applications, and this is due to their attractive features such as absence of any kind of windings or permanent magnets on the rotor structure. In this...
Rehabilitation for neurological patients as stroke or spinal cord injury is important for improving the quality of their lives. Furthermore, sustaining the properties of muscular tissue is necessary to prepare the other therapeutics. Passive exercise is a technique to maintain the tissue and prevent complication as deep vein thrombosis (DVT). Since, these patients cannot move their legs by themselves...
Perishables need special conditions within the food supply chain like temperature or humidity. There is a lack of information along the food supply chain (FSC) concerning temperatures for perishable goods. By integrating the Intelligent Container (IC) within the Internet of Things the lack of information will be eliminated and thus wastes of food will be reduced. The first step for this integration...
This paper presents a classically trained Multi-Layer Feedforward Neural Network (MLFNN) technique for predicting the output from a Grid-Connected Photovoltaic (GCPV) system. In the proposed MLFNN, the selection of the training parameters was conducted using a series of prescribed steps. The MLFNN utilized solar irradiance (SI) and module temperature (MT) as its inputs and AC kWh energy as its output...
A task that requires two hands to perform such as soldering usually needs additional tools for holding (e.g. a cable) or adding (e.g. solder) an object to a specific position. A robotic manipulator or robotic arm is one of the solution for this requirement. When gesture is selected as a method for controlling a robot, characteristics of gestures are needed for designing and developing a gesture recognition...
This paper presents a novel bat-like robot which can fly in air and adhere to various vertical wall surfaces or ceilings with much lower power consumption compared to typical flying robots of comparable physical dimensions. Various aspects in system design are discussed including several kinds of adhesion mechanisms, flying mechanisms, mechanical integration and controller design. The dynamic model...
The current standard approach for developing robot software applications is to use middleware for robotics. Protocols and paradigms have been set by the available middleware. However, not all of them share a common interface, resulting in difficulties when developing robot applications using software developed for different platforms. Even inside the same platform similar issues arise when software...
