WebIn this section, we explain static and dynamic obstacle avoidance while maintaining a smooth (i.e., no abrupt stoppage, and no sharp turns) trajectory. Obstacle avoidance incorporated with smoothing has been proposed in many previous works such as [34,35,36,37], and a review of all the works can be found in [38,39,40,41]. Webthe dynamic obstacle is proposed for mobile robot to plan the obstacle free path [12]. The bond graph (BG) is a useful technique to model complicated systems. BG approach is extensively applicable in vehicle dynamics [13]. BG is used to study the bicycle vehicle model for obstacle avoidance using overwhelming controller [14].
