Robotic systems

Definition

Robotic systems are integrated assemblies of hardware and software designed to perform tasks autonomously or semi-autonomously. They combine mechanical components, sensors, actuators, and control algorithms to execute specific functions, often in dynamic environments. These systems are capable of adapting their behavior based on feedback from their surroundings, making them essential in various applications like manufacturing, healthcare, and exploration.
