This paper presents a study on the trajectory planning and design of indoor S-shape obstacle avoidance based on Bobac mobile robot. The combination of lidar sensor and two-wheel control was used to realize the trajectory planning of S-shape obstacle and achieve precise positioning for the purpose of obstacle avoidance. The Bobac intelligent mobile robot platform was mainly taken as the research object for analyzing the problem of inaccurate mileage information in intelligent mobile robots, and establishing an environment model based on the grid Fast SLAM method to improve computing efficiency and positioning accuracy. Through the in-depth analysis of the relationship between lidar accuracy and distance, a method of S-shape obstacle avoidance in the precise area and the fuzzy area was proposed. A motion model and lidar sensor measurement error model for real-time correction were also introduced. In addition, the adaptive control method was used to estimate the distance between the bobac robot and the obstacle in real time and the mobile robot was controlled to gradually track the desired trajectory, proving the stability of the two-wheel real-time control and lidar cooperation. Experiments showed that, compared with the traditional lidar collision avoidance method, the proposed method can effectively improve the obstacle avoidance movement in the S-shape obstacle.
