After discussion about BRAIN of Robots now it is time to discuss about Electrical Power and types of electrical power we are going to use or we can use in our Robots.
The electrical power supply consists of a raw power source, a regulating circuit to stabilize and process the source, and a switch to activate and deactivate.
Basically hobby robots are supplied power from popular consumer batteries (AA, AAA, 9V batteries). Consumer batteries are safe, inexpensive, readily available, reliable, and standardized.
Rechargeable batteries are preferable. Although their initial cost is higher, they’ll save the experimenter a lot of money in the long run.
Solar power is also an option. Because light isn't constantly available, rudimentary solar-powered robots operate in repeating charge and discharge cycles, powering off between bursts of activity. More sophisticated solar-powered robots recharge batteries during optimal lighting conditions, with the batteries maintaining power to the brains during dark conditions.
Most robots have a small portion of their bodies dedicated to keeping a steady, specific level of power available to all of the electronics. This is called power regulation.
As batteries are used up, they provide less and less power. Unless stabilized, this would result in a robot that moves at different speeds and has different light brightness and sensor readings based on battery freshness. Another reason for power regulation is that some parts of the robot need more power than other parts. For example, motors require more power than logic chips or blinking lights. The power regulation module steps down (or, conversely, boosts) the battery power to the range needed by each major part.
Most robots have power switches. This allows the robot to be disabled for maintenance or storage.
Interestingly, solar-powered robots usually don’t have a power switch. Those robots wake up in the morning sunshine and dance all day.
