| Internal sensors are used to monitor and assess the internal state of the robot itself, ensuring smooth operation and effective control. | External sensors in robots are devices that detect environmental factors outside the robot. |
| These sensors provide feedback on mechanical and electrical functions within the robot. | These sensors enable robots to navigate, recognise objects and interact with surroundings. |
| They help in maintaining balance, stability and performance of the robot. | They help the robot to sense distance, detect objects and understand the environment. |
| Examples include position sensors, velocity sensors, acceleration sensors and force sensors. | Examples include cameras, LiDAR, ultrasonic sensors and infrared sensors. |
