Robotics is a rapidly growing field, and the innovative idea to scale down the size of robots to the nanometer level has paved a new way of treating human health. Nanorobots have become the focus of many researchers aiming to explore their many potential applications in medicine. This paper focuses on manufacturing techniques involved in the fabrication of nanorobots and their associated challenges in terms of design architecture, sensors, actuators, powering, navigation, data transmission, followed by challenges in applications. In addition, an overview of various nanorobotic systems addresses different architectures of a nanorobot. Moreover, multiple medical applications, such as oncology, drug delivery, and surgery, are reviewed and summarized.

Initial Concept

The paper presents an initial concept of a flying object trajectory recording system employing a data recording algorithm (operating on the base of the raw recorded data) and radio transmittion modules. Operation of developed system is based on microcontroller Atmega, a magnetometer module, a gyroscope and acceleration meter, and a RF miniature transmitter and SDR receiver. The initial performance of application analysing and recording the data is provided. Moreover, subunits available on the market have been reviewed to select the modules dedicated to the system. A possibility for record-ing the transmitted navigation data was studied. Application of SDR receiver in combination with a computer application monitoring the data transmission channel up to 1 kilometre is described with the configuration of the system, and the schematic of measurement transmitting and receiving modules, and the surveillance of transmitted data quality. The basic algorithm of application using the received data for reconstruction of object’s flying path and prediction of a fall point is presented. Moreover an analysis is included for possible applications of the above mentioned system.

The paper is focused on the navigation data exchange between two satellites moved in a swarm. The feedback control law is designed ensuring regulation of the relative satellites motion. The adaptive binary coding/decoding procedure for data transmission over the limited capacity communication channel is proposed and studied for the cases of ideal and erasure channel. Dependence of the regulation time on the data transmission rate is numerically found. The results obtained provides dependence of the required load of the communication channel on the desired quality of the stabilization process. It is demonstrated that for significantly high data transmission rate erasure of data in the channel with probability up to 0.3 does not make an effect on the regulation time.

Abstract In the article, the author proposes a method for constructing a small-sized unmanned vessel with a communication system with its operator, receiving data on control actions for the purpose of navigating the vessel in automatic and manual modes along a given trajectory, transmitting the necessary kinematic and navigation data for identifying mathematical models of the movement of sea-surface vessels, setting up the automatic steering in real time, as well as entering proofreading into sensor readings via the data transmission protocol via TCP-IP stack on public Wi-Fi radio frequencies. The method of constructing a small-sized unmanned vessel and its automatic wiring allows us to work out the principles of creating full-scale, fully functional unmanned cargo, passenger and military vessels. It allows you to work out the principles of creating automatic control systems for a given trajectory for fully functional crewed and unmanned vessels for various purposes. This method can be used to study the principles of construction and identification of mathematical models of vessel movement. The method proposed in the article was implemented at the competition “Talent and Success” of the “Sirius” educational center, where it successfully won the championship in the category “Marine Intelligence”.

Erasure Probability

The paper deals with the navigation data exchange between two satellites moving in a swarm. It is focused on the reduction of the inter-satellite demanded communication channel capacity taking into account the dynamics of the satellites relative motion and possible erasures in the channel navigation data. The feedback control law is designed ensuring the regulation of the relative satellites motion. The adaptive binary coding/decoding procedure for the satellites navigation data transmission over the limited capacity communication channel is proposed and studied for the cases of ideal and erasure channels. Results of the numerical study of the closed-loop system performance and accuracy of the data transmission algorithm on the communication channel bitrate and erasure probability are obtained by extensive simulations. It is shown that both data transmission error and regulation time depend approximately inversely proportionally on the communication rate. In addition the erasure of data in the channel with probability up to 0.3 does not influence the regulation time for sufficiently high data transmission rate.

Abstract The problem of the safety navigation considered only in terms of position error measurement, seems to be solved on a global scale. Thus, the operational characteristics of radio navigation systems such as availability are equally important. The integrated navigation system operate in a multi-sensor environment and it is important to determinate a temporal validity of data to make it usable in data fusion process. In the age of digital data processing, the requirements for continuity, availability, reliability and integrity information are already grown. This article analyses the problem of time stamp discrepancies of dynamic AIS class B position reports. For this purpose, the statistical summary of Latency Position Reports, derived from class B units has been presented. The navigation data recordings were conducted during 82 days of August, September and November 2014 from 20 vessels located in area of VTS ‘Zatoka Gdańska’. On the base of Latency Position Reports class B it is possible to designate the availability of AIS information system. For this purpose, the model of availability of AIS binary data transmission and research outcomes have been presented.
