Libraries.Robots.Lego.Battery

The Battery class is an object representation of the LEGO Mindstorms EV3 Battery. It is only used to get information about the current battery usage.

Example Code

use Libraries.Robots.Lego.Battery
use Libraries.Robots.Lego.Motor

class Main
    action Main
        Motor motor
        Battery battery

        motor:SetSpeed("A", 200)
        number batteryCurrent = battery:GetCurrent()
        repeat while true
            batteryCurrent = battery:GetCurrent()
            if (batteryCurrent < 0.05)
                motor:SetSpeed("A", 1000)
            else
                motor:SetSpeed("A", 200)
            end
            motor:RotateForward("A")
        end
    end
end

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Example Code

Object o
        Object t
        integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

This action determines if two objects are equal based on their hash code values.

Example Code

use Libraries.Language.Object
        use Libraries.Language.Types.Text
        Object o
        Text t
        boolean result = o:Equals(t)

This action gets the current (in amps) flowing from the battery.

Example Code

use Libraries.Robots.Lego.Battery
    
    Battery battery

    number current = battery:GetCurrent()
    if current < 0.05
        output "The electrical current coming from the batteries is: " + current
    end

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

This action gets the total voltage (in volts) coming from the batteries. This value should be somewhere around 6 through 9.

Example Code

use Libraries.Robots.Lego.Battery

    Battery battery

    number voltage = battery:GetVoltage()
    output "The voltage coming from the batteries is: " + voltage + " volts."
