Established a unified equation of conical surface cutting line, analyzed the main cutting line critical characteristics, studies the section curve of plane problems, discussion plane curve property, continuous planar interception solution of two types of components are presented.
This paper uses cone cutting line method and plane curve generation method to study the cone section and plane expansion method, establish the transformation of different form curve. This paper analyzes bounded cone section characteristics and components of graphic design methods, combined with specific models, gives cone component integration design and production methods.
Through the analysis of the glass wall and solar panel cleaning robot research status at home and abroad, based on cleaning characteristics and requirements of such kind of smooth surface, a full pneumatic-driven flat surface cleaning robot system is presented. The robot adopts unique three-position cylinder driving technique, SCM and PC two-level control, can crawl along the smooth surface and clean, and can overcome obstacles in a certain height. Running results show that the robot system has simple structure, low cost, the functions of on-line fault diagnosis, and can provide a new efficient, simple and safe way for the glass wall and solar panel cleaning.
In this paper, the state observer design is considered for a class of nonlinear neutral delay system with nonlinear uncertainty based on Lyapunov stability theory. On condition that the nonlinear uncertain functions are gain bounded, a sufficient condition is presented for the existence of a linear feedback from interference input to control output. The less delay-dependent sufficient stability conditions for these systems in terms of linear matrix inequalities (LMI) are derived. By solving a linear matrix inequation, we can obtain the controller and observer of this system.
Through the analysis of the research status and application characteristics of the pipeline robot, a design of pipeline and slot multi-function robot is presented. The robot adopts pneumatic power systems and peristaltic walk way. The robot can move not only in reducing pipe to clean or detect, but also between the slot to rescue or transfer goods according to computer instructions. The system is operated by slave control unit and controlled by PC through an auxiliary rope, so the robot has advantages about real-time detection of the work state, strong driving force, easy maintenance and fault recovery, low cost and so on.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
