Mobile robot simultaneous environment exploration and map base building

Compared with the research on the path planning in static known environment, the unknown environment and dynamic changes bring new challenges to the path planning of environment exploration for mobile robot.

In order to meet the demand for robot navigation,exploration and cognition,this paper provides a method of autonomous environment exploration based on exploration-direction-point and an algorithm of composite map base building using laser scanning.

Objective To study the effect of exploratory environment on behavioral recovery and the expression of neurogranin(Ng) in rats after unilateral local cerebral infarction.

Beginning with the factors which affect one s English reading comprehension,this paper has proposed that analysing context clues be in favor of improving the ability to read and comprehend so as to cast a brick to attract a jade____offer a few commonplace remarks by way of introduction so that others may come up with valuable opinions.
