Mozgástervezés, often translated as motion planning, is a fundamental problem in robotics and artificial intelligence. It involves finding a sequence of movements for a robot or agent to move from a starting configuration to a goal configuration while avoiding obstacles. This process is crucial for autonomous systems that need to navigate complex environments.

The core challenge in motion planning lies in the high dimensionality of the robot's configuration space and the complexity of the environment. A robot's configuration is defined by its position and orientation, and for robots with multiple joints, like a robotic arm, this space can have many dimensions. Obstacles in the environment further constrain the possible movements, creating a "free space" where the robot can move without collision.

Various algorithms have been developed to address motion planning. Probabilistic roadmaps (PRMs) build a graph of reachable configurations by randomly sampling points in the free space and connecting them if a collision-free path exists between them. Rapidly-exploring random trees (RRTs) grow a tree-like structure from the start configuration, exploring the space efficiently by biasing towards unexplored regions. Other approaches include grid-based methods, potential field methods, and optimization-based techniques.

The success of a motion planner depends on factors such as the dimensionality of the configuration space, the complexity of the environment, the desired path quality (e.g., shortest, smoothest), and the computational resources available. Motion planning is an active area of research, with ongoing efforts to develop more efficient, robust, and versatile algorithms for increasingly complex robotic applications.
