Overview of Sensor Based Motion Planning For Path Tracking And Obstacle
Then the turning radius for avoiding an obstacle , which is inversely proportional to the virtual force, is calculated. By integrating the geometric path tracking method and the sensor-based obstacle avoidance method, the vehicle follows the waypoints and avoids unexpected obstacles while it considers the motion constraints.

Path planning techniques for mobile robots
In the local path planning , we introduce the sensors commonly used in the detection environment, including laser radar and visual sensor . Next, according to the characteristics of algorithms, mobile robot path planning algorithms are divided into three categories: classical algorithms, bionic algorithms and artificial intelligence algorithms.
To address this limitation, we introduce SPOT (Sensing-augmented Planning via Obstacle Threat modeling), a unified planning framework for observation-aware trajectory planning that explicitly incorporates sensing objectives into motion optimization.
