I am building a robot with multiple types of sensors, 2 motors for locomotion, 2 motors to control a robotic arm. I want to know how do i factor in all these components to determine a length of how long my battery will last. Lets say I was using a 7.2 V/1600 mAh, now how could I determine its length of life using the voltage and current of each component. I am using a variety of color,IR, tilt sensors and such. So could someone give me a good solution.
