Rapid information gathering during the initial stage of investigation is an important process in case of disasters. However this task could be very risky for human rescue crews, when the infrastructure of the building has been compromised or the environment contaminated by nuclear, biological, or chemical weapons. To be able to develop robots that can go inside the site instead of humans, several...
In this paper, a new category of wheel-leg hybrid robot inspired by retracting configuration of the armadillo is presented. The proposed mechanism can compose large wheel diameter compared with the previous hybrid robot to realize high ability to climb obstacles. A prototype model of one wheel-leg module of the proposed robot mechanism has been developed to illustrate the concept. Actual design and...
In this paper, we propose an action planning algorithm and its evaluation method based on dynamic simulation for a novel type of hybrid leg-wheel rover for planetary exploration. Hybrid leg-wheel robots are recently receiving a growing interest from the space community to explore planets, since they offer an appropriate solution to gain improved speed and mobility on unstructured terrain. However,...
On a scene of a natural disaster, rescuers require heavy duty hydraulic machines to answer their need of large forces, or to approach an unreachable spot. Those industrial vehicles are hydraulically actuated arms kinematically different, and equipped by specific tools to fit the task to accomplish. They require trained operators because of their complex use. As time and accuracy are primordial factors...
In this paper the authors present the current progress of a networked robotic system intended to be deployed at disaster areas. This system is formed by three mobile robots: two twin crawlers that would have search-and-recognition tasks gathering information about their surroundings, and an outdoor-wheeled rover that will approach the area and which will also carry the two crawlers. The communication...
This paper describes the ongoing development of a tele-operation platform for space robotic missions. The proposed platform consists of a ground control station, an offline simulation environment, a full-scale working model of the robot and the actual robot on the mission. From the simulation environment a path strategy is obtained and a set of commands is generated and sent to the ground control...
