    The work presents the concept of providing a Personal Area Network (PAN) for microcontroller based mobile robots using Bluetooth transceiver. With the concept of replacing cable, low cost, low power consumption and communication range between 10m to 100m, Bluetooth is suitable for communication between mobile robots since most mobile robots are powered by batteries and have high mobility. The network aimed to support real-time control of up to two mobile robots from a master mobile robot through communication using Bluetooth transceiver. If a fast network radio link is implemented, a whole new world of possibilities is opened in the research of robotics control and Artificial Intelligence (AI) research works, sending real time image and information. Robots could communicate through obstacles or even through walls. Bluetooth Ad Hoc topology provides a simple communication between devices in close by forming PAN. A system contained of both hardware and software is designed to enable the robots to form a PAN and communicating, sharing information. Three microcontroller based mobile robots are built for this research work. Bluetooth Protocol Stack and mobile robot control architecture is implemented on a single microcontroller chip. The PAN enabled a few mobile robots to communicate with each other to complete a given task. The wireless communication between mobile robots is reliable based from the result of experiments carried out. Thus this is a platform for multi mobile robots system and Ad Hoc networking system. Results from experiments show that microcontroller based mobile robots can easily form a Bluetooth PAN and communicate with each other

    Wireless communication of video, with Bluetooth as an example, represents a compromise between channel conditions, display and decode deadlines, and energy constraints. This paper proposes fuzzy logic control (FLC) of automatic repeat request (ARQ) as a way of reconciling these factors, with a 40% saving in power in the worst channel conditions from economizing on transmissions when channel errors occur. Whatever the channel conditions are, FLC is shown to outperform the default Bluetooth scheme and an alternative Bluetooth-adaptive ARQ scheme in terms of reduced packet loss and delay, as well as improved video quality

    This master thesis evaluates control algorithms for control applications using Bluetooth in the loop. It is done in order to investigate whether Bluetooth can be used in hard real-time control loops or not. The control algorithms suggested in this work are evaluated on a real process, the Furuta pendulum, due to the unstable nature of the process. This will assure that the Bluetooth communication is pushed to its limits, where problems can be found. Problems encountered are bandwidth limitations, retransmissions in the low layers of Bluetooth and disturbances to the wireless communication

Drama stage lighting control device with Bluetooth is working with the media is controlled by an ATmega16 microcontroller IC with control systems that are created using the C language Programming language created using software (CodeVision AVR). Hardware that supports consist of a series of power supply, EB500 Bluetooth module as a data receiver, IC ULN3803 as relay driver, relay for activating the lights and as a processor ATmega16 microcontroller. Mobile as a controller using the brand Sony Ericsson K608i with the type of Java software applications Avic B Controller. Having performed experiments and analyzed it can be seen that the hardware has been successfully fabricated using minimum system ATmega16 microcontroller combined with other supporting instruments. The software has been successfully designed using the C programming language using CodeVision AVR decompile. The performance of this instrument as a whole has been in accordance with a predetermined function, which is well able to control the stage and lighting effects dramatize the appropriate criteria for lighting the stage drama. In a control tool is also found flaws in the software used in mobile phones that have come out of the program first before sending the next command and distance for lighting control only about 7 meters. This tool has received validation from the LB. Suraja a dance coach and administrator at Prambanan Ramayana Ballet who claimed this tool is sufficient to meet criteria and developed as it is possible to control lighting in a real drama

    Currently technology is highly developed and supports many new innovations. The most innovation is wireless technology and voice recognition. One of the widely used wireless technology is Bluetooth. By utilizing Bluetooth connectivity and voice recognition applications on smart phones, it can be used to control electronic equipment. In this study, voice recognition applications and Bluetooth connections will be used on smart phones to control electric wheelchairs. This research begins with designing an electric wheelchair. For Bluetooth communication using the HC-05 Bluetooth module. The wheelchair was developed by modifying conventional wheelchairs to become electric. The user or patient will control the wheelchair using his smart phone through the voice recognition application. Commands in the form of voice that will be sent by the smart phone and received by the HC-05 Bluetooth module, then become input for the Arduino microcontroller. The microcontroller will then process the input data and will instruct the motor driver to give instructions to the wheelchair driving motor. The electric wheelchair's voice control system with a Bluetooth connection can work quite well. The Bluetooth connection used in this electric wheelchair voice control system works optimally and well at a distance of <10 meters, the connection starts to drop at a distance of 10 to 23 meters, and the connection is lost when the distance is 30 meters. The results of the voice recognition test on voice commands were successful with an accuracy of 85%. The total test is 100 orders with a total error of 15 orders

    A house consists of several rooms with electronic devices inside of it. Each device has a remote control or a button to control it. With technologies have been increasing rapidly, we can control home appliances easily with our Android smartphone. However, this can make user uncomfortable to control,  if all the devices appear simultaneously in one screen. Therefore, this project aims to develop an automatic configuration remote control system which adapts to the situation of the room to be controlled. Using Bluetooth technology in smartphone for transfering data. Usually to connect to a Bluetooth device, user manually chooses one of the Bluetooth device names from the list that appears from the scan results. Therefore, the focus of this project is to develop a wireless control system that is capable of performing automatic configurations that suit the situation of the room. This system uses a localization method that utilizes the signal strength that Bluetooth  receives or RSSI Bluetooth. The testing result of the system are able to perform automatic configuration where the system is automatically connected to the nearest room without the need for prior settings and adjust the control menu according to the situation of the room
