Many mobile robots especially tracked robots have been developed and used in disaster sites, however, few robots can really work in a nuclear accident. This paper presents a procedure of making a robot for nuclear accidents. Concepts and calculations before designing the robot are introduced, then Autodesk Inventor is used for designing the 3D model, Recurdyn is used for the dynamic simulation. After...
This paper designs a MCU-based robot fish with caudal fin in order to model the robot fish and verify the related control methods. Firstly, this paper presents an overall design according to the functions required and then chooses the ideal servo motor after calculating its parameters based on the amplitude and frequency of the sine law. In addition, the controller, the inertial navigation model,...
With the rapid development of wireless sensor networks in the recent past, many programming tools have been proposed. It is difficult to provide an accurate comparison because of the different implementation. In this paper, an application based benchmark suit has been proposed. The workloads are selected based on the general application of the sensor nodes and the metrics are selected according to...
Analyzing the ever-growing market prospects of mobile map services and widespread applications of J2ME client techniques, the paper, firstly, discusses J2ME advantages compared with WAP and BREW in aspects of Web interaction, in-situ data storage or access, software development efficiency etc. And then, it puts emphasis on such programming keynotes as map blocking and local multi-level caching in...
A novel modified digital pulse interval modulation (MDPIM) is presented on the basis of pulse position modulation (PPM) which needs symbol synchronization and digital pulse interval modulation (DPIM) whose symbol length is not Modified. After introducing symbol structure, average transmit power and bandwidth efficiency are studied. Based on weak turbulence channel model, the slot error rate and packet...
