Rescue robot, a helper to find victims and take some action in place of human in a disaster area, has attracted attention since mobile robots had been developed. Among various functions of rescue robots, real-time obstacle avoidance is definitely key issue to realize realistic scenario. Obstacle avoidance is taken as one of the driving modes of the VSTR(Variable Single-tracked Robot), testbed which is able to traverse difficult environment with two driving modes in hardware, and determined when the VSTR meets with insurmountable obstacles. 2D LMS(Laser Measurement System) get radial distance data centered on a robot to know where is safe to avoid, and the ELA(Emergency Level Around), our algorithm for obstacle avoidance, is released to steer a robot safely and quickly based on the emergency level to judge where the optimal free space is. After development of the algorithm, we define performance indices of the ELA as rapidity and inspectability, and test the performance by simulation to demonstrate superiority of the ELA.
