Snake-like robots of the Genbu series (Genbu 1,2,3) consist of multiple modules, equipped with active wheels, connected to each other by passive joints. These robots are categorized as Active-Wheel Passive-Joint articulated mobile robots (AW-PJ type). AW-PJ type robots have high-speed mobility and high-durability on rough terrain in spite of several problems, such as stuck condition, due to the passive joints. These are good properties for fire-fighting robots or planetary rovers. Genbu 3, developed in this study, could climb a 280mm vertical wall whereas the diameter of the wheel is 250mm. This paper describes the design concepts and the original mechanisms of Genbu 3. Automatic stuck detection algorithm and stuck avoidance methods are discussed. Para-skid steering is also described. Results of experiments with Genbu 3 are presented and discussed in order to verify these methods.

Modeling And Analysis

Multiple high speed CMOS cameras composing intersection system to splice large effect field of view(EFV). The key problem of system is how to locate multiple CMOS cameras in suitable position. Effect field of view was determined according to size, quantity and dispersion area of objects, so to determine camera position located on below, both sides and ahead to moving targets. This paper analyzes effect splicing field of view, operating range etc through establishing mathematical model and MATLAB simulation. Location method of system has advantage of flexibility splicing, convenient adjustment, high reliability and high performance-price ratio.

MOST (Media Oriented Systems Transport) protocol is a high-speed multimedia bus protocol. The system can make more and more media devices in the car automatically collaborate, sharing of audio, video and other data, but its own power consumption has not been a better optimization. In the paper, depending on the network management and the notification mechanism, a distributed power management solutions was designed that the slave nodes can sleep independently and the master node manages the network state, and the wake-up mechanisms in the sleep state were proposed. A mathematical modeling and analysis of MOST networks power were built in MATLAB. This program takes full advantage of MOST network protocol for the intelligent management. Simulation results shown that, with the increasing number of nodes in MOST, energy saving become more effective. More than 20% power saved can be achieved with distributed power management solution in 8-node MOST.
