In this study, multiple control systems were developed using commonly used wireless communication protocols like Bluetooth, Xbee, and Wi-Fi. Mechanical switch based control systems were initially designed using Xbee and Bluetooth protocols. Further, Android application based control systems were developed using Bluetooth and Wi-Fi protocols. A robotic vehicle was used as an electric-powered wheelchair prototype. Ultrasonic sensors and infrared sensors were integrated with the robotic vehicle for obstacle and pothole detection, respectively. The control systems were tested in an L-shaped corridor for identifying the suitable wireless communication protocol to efficiently guide the robotic vehicle through a scheduled navigational pathway. Both Xbee and Wi-Fi technology based control systems were able to guide the robotic vehicle through the corridor. But the implementation of Xbee communication protocol is economic. However, for shorter distances, Bluetooth technology may be used for cost-effective implementation.

Wireless Communication Protocol

Although the number of Internet of Things devices increases every year, efforts to decrease hardware energy demands and to improve efficiencies of the energy-harvesting stages have reached an ultra-low power level. However, no current standard of wireless communication protocol (WCP) can fully address those scenarios. Our focus in this paper is to introduce treNch, a novel WCP implementing the cross-layer principle to use the power input for adapting its operation in a dynamic manner that goes from pure best-effort to nearly real time. Together with the energy-management algorithm, it operates with asynchronous transmissions, synchronous and optional receptions, short frame sizes and a light architecture that gives control to the nodes. These features make treNch an optimal option for wireless sensor networks with ultra-low power demands and severe energy fluctuations. We demonstrate through a comparison with different modes of Bluetooth Low Energy (BLE) a decrease of the power consumption in 1 to 2 orders of magnitude for different scenarios at equal quality of service. Moreover, we propose some security optimizations, such as shorter over-the-air counters, to reduce the packet overhead without decreasing the security level. Finally, we discuss other features aside of the energy needs, such as latency, reliability or topology, brought again against BLE.

Search For Information

The project aims to design and build a robotic platform, capable of uploading tools for drilling exploration processes in unstructured environments. With the characteristic of being maneuvered remotely through a wireless communication protocol and a support system to allow new routes autonomously, without human intervention. During the last 4 years the research group DAVINCI has acquired knowledge in the search for information and has developed three mobile remotely controlled for a specific purpose, to neutralize the explosives and manipulate objects platforms. The information held for the development of mobile robots can be extrapolated to other functions, can be applied to other work tasks can be mining, agriculture and exploration. For the particular case the project to develop a robot that I carried out in mining support tasks remotely by tele-operation and support of autonomous system is presented.

This paper presents an approach for design and realization of a smart device for measuring and monitoring ammonia concentration. The developed system included two parts: hardware and software, in which the hardware of the system has been developed based on the ATMEGA328P microcontroller in order to collect data from the ammonia sensor MQ135. Meanwhile, the software is developed for signal processing and warning according to different thresholds. Collected data by the system is then transmitted to a computer via the wireless communication protocol. In addition, an interface is also designed on computers to collect and monitor data from sensors. The developed system allows to measure ammonia concentration up to 300ppm and has been tested not only at the laboratory but also at NPK factory of Lamthao Fertilizers and Chemicals Joint Stock Company. Experimental results show the desired performances of the developed system.
