Mobile sensor platform

One potential approach for improved accuracy is sensor fusion, whereby readings from multiple, functionally different sensors are combined to estimate the soil properties of interest. For example, a commercial mobile sensor platform (Fig. 2.6) combined the soil pH sensing system described in reference (155) with soil apparent electrical conductivity (ECa) sensing. As ECa provides a strong indication of soil texture variations, the combination of the pH and ECa data was useful for establishing lime requirements. An NIR reflectance sensor was later added to this multi-sensor platform. ...

Finally, the long-standing limitation of ion mobility instruments as point sensors with all the limitations may be solvable with multiple instruments either distributed through some area or region or on airborne platforms in motion. This has been demonstrated with the unmanned airborne vehicle (UAV) work of C. S. Harden and colleagues and could develop with reduced size and cost of ion mobility analyzers and UAVs. 

Mobile health (mHealth) is an emerging concept which refers to the combinational use of mobile computing, communication technologies, and medical sensors for healthcare [1]. In addition to the passive provision of health-related information via mobile platforms, its scope also extends to more active applications such as disease management, medical prognosis, diagnosis, and even treatment. A typical mHealth system is characterized by its features of mobility, wireless connectivity, location independence, and timely response— which together provide seamless and personalized healthcare. 

SHOAL was not the first project to develop a robot that mimics the behavior of fish. Unlike the other projects, which are based on a sophisticated robotic platform, the Bayen group from UC Berkley designed a simpler system (see Fig. 23.16). They based their system on a mobile floating sensor network. The sensors were put into a floating device equipped with a cellidar device (smart-phone) which served as the microprocessor. The devices were then scattered in estuarine environments and rivers and were carried by the current trough the area of interest. The data from the... 

Multi-robot cooperative localization is a challenging task in mobile robotics, and it is the basis for both multi-robot navigation and exploration. Mobile platforms in the team are able to cooperate and estimate their poses in the environment. Robots in a cooperative localization system are able to make full use of their sensor information to refine their internal estimation and to improve their localization accuracy. Furthermore, the ability to exchange information during localization is particularly attractive, because each sight of another robot reduces the uncertainty of the estimated poses. This means that teams have to be designed to build a network infrastructure in order to perform cooperative tasks. 

The mechanical design of the mobile robot was performed using CAD/CAE technologies in which the main features ofthe dam and its peripherals were considered. Then, some sensors were installed on the platform some ofthe sensors were used by the control and navigation system and others to analyze water quality. Finally, the AUV was subj ected to several tests in a real environment to validate the vehicle. Experimental tests were successful and the preliminary results showed that the vehicle behaved according to design specifications in the the proposed environment.
