Robot Power supply setup
In this section, we will discuss setting up the power supply for the Raspberry Pi Zero. We will discuss powering the Raspberry Pi Zero and the motors of the robot. Let's discuss the major components of our robot and their power consumption:
- The Raspberry Pi Zero requires a 5V power supply, and it draws about 150 mA of current (Source: http://raspberrypi.stackexchange.com/a/40393/1470).
- The two DC motors of the robot consume about 150 mA each.
- The camera module consumes 250 mA of current (Source: https://www.raspberrypi.org/help/faqs/#cameraPower).
The total power consumption estimate is about 550 mA (150 + 150*2 + 250).
In order to calculate the battery capacity, we also need to decide the duration of continuous ...
