Urucu, deep in the Amazon forest, is the largest in-land natural gas and oil producing site in Brazil. The oil and gas extracted in Urucu travel some 700 km in a pipeline through the jungle until they reach Manaus, where they are refined and consumed. Exploration of the site is conditioned on the Brazilian oil company Petrobras monitoring a 400 km section of the pipeline for any signs of water contamination. The Environmental Hybrid robot (EHR) was conceived to automate this humongous monitoring task, currently executed in extremely small scale by scientists and locals on foot and small boats. This paper describes the design, analysis, and testing of the EHR's second-generation locomotion mechanism, based on a two-DOF parallel mechanism. The new mechanism allows for independent control of wheel position and orientation relative to the terrain, thus significantly increasing the robot's mobility. Additionally, it allows for control of the vehicle's velocity-torque curve by adjusting the radius of curvature of the wheel at the point of contact with the soil. We present the forward and differential kinematic models of the new mechanism and, based on them, a differential kinematics-based position and orientation control method. We illustrate the methodology with experimental results.

This paper presents a formation control method of multi-robot based on A* algorithm for data relay transmission. In our system, we choose Nanotron sensor and compass sensor to execute the tasks of distance measurement, communication and obtaining moving direction. Since there exists data disturbance from Nanotron sensor when there is an obstacle between two robots. Therefore, we embed path planning algorithm information control. The leader robot (LR) knows the whole information of environment, and sends its moving information and corner information as a node to FRs. The FRs regard the node information which received from LR as temporary target to increase the efficiency of multi-robot formation by optimal path. From the simulations and experiments, we will show desirable results of our method.

Over the past decade, an increasing number of researches and developments for personal or professional service robots are attracting considerable attention and interest in industry and academia. Furthermore, the development of intelligent robots is strongly promoted as a strategic industry. To date, most of the practical and commercial service robots are controlled remotely. The most important technical issue of remote control is wireless communication, especially in indoor and unstructured environments where communication infrastructure may be hampered. Therefore, we propose a multi-robot cooperation navigation method for securing the communication distance extension of the remote control based on wireless personal area networks (WPANs). The concept and implementation of following navigation are introduced, and performance verification is carried out through navigation experiments in real or test-bed environments.
