Application of a vision system and a remote control car to an elective fourth year design project in electrical engineering is discussed. The design project involves learning and application of various sensors, actuators, control theories. The end product of the design project is an intelligent vehicle that is able to follow an emulated highway automatically. A camera with embedded color tracking...
Nowadays, the intelligent appliance is becoming an integral part of the smart home. In this paper, we adopt AVR microcontroller atmega64 and relevant signal process circuitry to design a control system, which is used to control the intelligent toilet. After an overview of the hardware and software design of this control system we analyze some detailed design. A series of conflicts encountered in the...
Sensor networks have come a long way since their humble beginnings in DARPA-funded academic research projects in the 1990s and have morphed into a significant research area in their own right. Over the last decade or so, networked sensing devices have become embedded all around us. In this article we look at how sensor network research and applications have evolved and how emerging trends could determine...
In this paper, we proposed a model based sensor fault tolerant control system embedded in a generic PIC microcontroller for use in a temperature control system. The model based fault tolerant control algorithm is embedded in the microcontroller for stand-alone real-time implementation. The algorithm consists of a PID controller element (for nominal control) and a fault compensating element. Results...
Although most students are familiar with computers, very few of them know that they are meeting with embedded computers daily. The aim of our work was to develop an embedded system that is compelling for students with various interests. Thus, we decided to develop a musical instrument. In this paper we present the musical instrument functionality and architecture. We discuss its possible applications...
This paper will explain a new way to communicate between mobile robots based on PC- Card and some sensors using in robot application or mobile robot research. The hardware interface with the Inter-Integrated Circuit System or shortly I2C bus system will be mainly described here. The mobile robot components, I2C bus system and some I2C slave devices are also introduced. Finally, the software is developed...
Wireless sensor network (WSN) is a distributed system which possesses time varying wireless connectivity without any infrastructural backbone. Scarce energy and computation power of individual nodes, unattended and harsh operation environment, self configuration after random deployment etc complexities are known characteristic features of a WSN. Despite aforesaid constraints WSN has been evolved as...
Japanese offices are often cramped, cluttered, and allow a mapping robot very little room for maneuvering. Robot navigation research in Japan is hampered by these cramped spaces and a thorough search for robots that could map and maneuver in Japanese offices turned up unsatisfactory results: either the robots were too large, could not carry a relatively heavy payload, or did not have processing power...
