The autonomous robots should be capable of recognition, learning and decision making. Path planning is an important issue in the field of robotics. It is a method to find collision free path from the start location to target location, given an environment consisting of obstacles. The path should be optimized using some reasonable algorithm where the optimization criteria can be time, distance or energy depending on the problem. This research will give an improved and efficient algorithm for robotic path planning that will generate an optimized path.

Path planning in unknown environment is very difficult task since the map of the environment is not certain. Though robots are employed with sensors and global positioning system but due to uncertainty

The space consists of some obstacles O and their positions and geometric characteristics are known to the robot prior. Given a start position S and the target location T, the path planning problem is to generate an appropriate path from S to T without any collision.

This research focuses on the path planning of mobile robot in dynamic environment. Following are the objectives of this research:
i. To develop an improved artificial bee colony algorithm for path planning in dynamic environment. This algorithm is expected to generate an optimal and feasible path from start position to target position and the results are expected to be better than previous work done for static environment [4]. ii. To develop an approach that will optimize the final path efficiently and to utilize this approach in determining the feasible and optimal path using improved artificial bee colony algorithm.
