Answer: Fixed robot.
Answer analysis: In robotics, there are two basic types of robots - fixed robots and mobile robots.
Fixed robot
Definition: A fixed robot is a robot that is fixed on a certain base. The entire robot (or manipulator) cannot move, and can only move each joint to perform operations.
Features: Because it is fixed on the base, its stability and precision are relatively high, and it is suitable for scenes that require high-precision operations and do not require large-scale movement.
Mobile robot
Definition: A mobile robot refers to a robot that can move in a certain direction or any direction.
Classification: Mobile robots can be divided into wheeled robots, tracked robots and walking robots according to different ways of movement. Among them, walking robots can be divided into single-legged, bipedal, quadrupedal, hexapodal and octapodal walking robots according to the number of walking legs.
Features: Mobile robots have higher flexibility and adaptability, and can perform mobile operations in different environments according to task requirements.
These two basic types of robots play their respective advantages in different application scenarios. Fixed robots are widely used in industrial automation production lines, precision machining and other fields due to their high precision and stability, while mobile robots have great potential in logistics handling, inspection, rescue and other fields due to their flexibility and adaptability. With the continuous advancement of technology, both types of robots are constantly developing and improving, bringing more convenience and benefits to human production and life.
