Abstract
When we operate rescue robots in desarster area, the most effective tool is visual infomation obtained by video cameras on the robots. However, the network transmission capacity in a traditional single channel Ad-hoc network is limited to 4-6Mbps in general. This amount of capacity is not enough because rescue robot mounts 2 or 3 cameras to gather enviromental infomation. This paper describes the development of robots with multiple channels Ad-hoc networking system to extend the scale of rescue operation.
