robotics
Robotics is a branch of artificial intelligence and engineering which is used for designing and manufacturing of robots.
Robots are the programmed machines which can perform a series of actions automatically or semi-automatically.
AI can be applied to robots to make intelligent robots which can perform the task with their intelligence. AI algorithms are necessary to allow a robot to perform more complex tasks.
Nowadays, AI and machine learning are being applied on robots to manufacture intelligent robots which can also interact socially like humans. One of the best examples of AI in robotics is Sophia robot.
