A very simplified description of how robots work is as follows: A robot is controlled by an in-built computer (microcontroller). This must be programmed so that the robot can carry out the desired activities. The latest generation of robots can use their sensors to collect data from their environment and modify the behaviour of their active components themselves.
Sensors are measuring devices that measure physical parameters such as brightness, distance, temperature, humidity, etc. Actuators are the active components of a robot (motors, LEDs). They execute commands that they receive from the microcontroller. The functioning of robots can also be demonstrated using simple robots such as the Callibot. |
