Abstract
In the field of robotic, there are some concerns that always grab the world attention which are the motion planning and control problem. Both of them will finally decide the collision-free trajectories for a robot in static or dynamic environments which may have many unknown obstacle around while seeking the goal. Thus this report describes the development of a behavior-based mobile robot for the obstacle navigation and goal seeking. The subsumption architecture will be utilized with the obstacle avoidance having higher priority over goal seeking. In fact, there are many possible obstacles that may keep the robot wandering around aimlessly seeking the goal. One of its main problems is local minimum problem which keep robot trapping in a corner. Owing to simplicity, wall following will be the better solution for that case. Beside that, a deadlock is also consideration in this paper. In the nutshell, the report will discuss all possible obstacles that may exist in the real world. However the goal seeking feature still has flaw when it is combined with the obstacle avoidance. Besides that, the designed robot will act as leader guiding the other robots which are the followers to avoid the obstacle around while searching the goal. This is called the leader-following.
