This paper aims to deliver movement of the robot by finding and traversing the shortest path in the static present grid, using source and destination positions entered by the user. The robot currently requires a grid since it traverses space using line-tracing. Further addition to the functioning - the robot avoids static obstacles which might be present in its path towards destination. A microcontroller (AtMega2560) was used as an interface between the hardware and our software program. The robot used was Firebird V. For line-tracing, infrared LEDs (transmitters) and photodiodes (receivers) present on the robot were used. The popular dijkstra's algorithm had been incorporated in our shortest-path follower code. The language used for programming is AVR.

With the development of the society and the changes of the traffic information on the urban road, Optimal path is no longer simply the shortest distance on the geographical location, but also taking into account the real-time traffic information. Meanwhile, with the development of the computer technology, communication technology and geographical information technology, intelligent navigation brings more benefits to people. It can save the trave time and reduce energy consumption. On the other hand, using intelligent navigation, people can avoid roadblock, traffic jams, traffic accidents etc. Intelligent navigation can provide a safer and more reassuring environment. Combining with the Internet of Things, this paper proposes an improved routing algorithm for dynamic traffic navigation based on the Internet of Things platform. GPS will download the real- time traffic information by accessing the built Internet of Things platform, calculate the optimal path precisely, and then provide real-time and more intelligent navigation service for people.

In order to shorten the inspection path and time-consuming, improve the intelligence degree of the laser inspection robot and apply to the large-scale TSP in the substation, the paper proposes a path planning method based on the improved ant colony algorithm, the navigation method, the walking characteristics, the inspection task and the road environment. This method uses the topological method to model the road environment. The dijkstra algorithm and the improved ant colony algorithm are used to plan the inspection path of the laser inspection robot. In this way, the laser inspection robot can re-plan the new inspection path for the remaining undetected task points after encountering an obstacle, and finally return to the starting point. In this paper, Visual Studio C++ is used to test the improved ant colony algorithm and Greedy algorithm. The results show that the improved ant colony algorithm has obvious advantages in path length and the number of passing points, which can realize that the inspection route of the laser inspection robot is optimal or sub-optimal. At the same time, the dynamic simulation of the method is carried out based on MATLAB. The simulation results show that the method can realize self-real-timely avoid obstacle and re-plan the new inspection route after encountering an obstacle. It can ensure the completion of the inspection task. And the method has good applicability, robustness and high efficiency.

On the basis of analyzing static routing algorithm and dynamic routing algorithms, this paper focus on the link state routing of the dynamic routing algorithm, puts forward a more concise routing way in the link state routing. dijkstra routing algorithm is suitable for calculating the shortest path from one router to other routers, but there are more point-to-point links in the computer network, Floyd routing algorithm is more suitable for calculating the shortest distance between two router, and it is more practical in the computer network.

Sharing-bikes are characterized by health, greenness and environmental protection, effectively solving the "last kilometer" problem. It is of great significance to reasonably plan the sharing-bike connecting rail transit routes to meet the traveler's needs, build safe urban traffic travel environment, and guide bicycle travel. Based on the shared bicycle trip data, this paper proposes an optimal paved lane path planning model for a sharing-bike connected rail transit based on traffic network. Based on spatial clustering and improved dijkstra's algorithm, the steps and principles for solving the model are given. The results of the example of Beijing No. 2 Line as a planning example show that this model has the characteristics of convenience of route layout and deployment cost, and has certain feasibility, which enriches the path planning method of bicycle lanes.
