Motion planning is a subfield of robotics that focuses on the development of algorithms and techniques to plan and control the motion of robotic systems in dynamic and uncertain environments. The goal of motion planning is to generate feasible trajectories for robots to navigate from an initial state to a goal state while avoiding collisions with obstacles and adhering to specified constraints such as velocity limits and smoothness requirements. Motion planning is a critical component in various robotics applications, including autonomous vehicles, industrial automation, and robotic manipulation. Researchers in this field develop algorithms that can efficiently and effectively plan safe and optimal paths for robots to accomplish their tasks in complex and unknown environments.
