Nowadays, there are few technologies for automatically charging a
robot at the charging station.
First of all, the robot needs
to go to the base station when the battery is low. Since we cannot
directly detect the battery level from the powerbank, we set a timer
in the coding of the robot. The robot will go find the base station
after several hours its on.
Locating the base station:
Infrared (IR) sensor technology.
This technology is used in
almost every cleaning robot. It is very common because it is rather
simple and cheap compared to other technologies, such as a camera.
This technology can make the robot identify each other and
return to the home base.
Both the robot and the base station will
be equipped with IR sensors. This will enable the robot to locate
and move on the signal emitted by the station at any time.
