Libraries.Robots.Lego.Battery Documentation
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

Summary
Actions Summary Table
Actions | Description |
---|---|
Compare(Libraries.Language.Object object) | This action compares two object hash codes and returns an integer. |
Equals(Libraries.Language.Object object) | This action determines if two objects are equal based on their hash code values. |
GetCurrent() | This action gets the current (in amps) flowing from the battery. |
GetHashCode() | This action gets the hash code for an object. |
GetVoltage() | This action gets the total voltage (in volts) coming from the batteries. |
Actions Documentation
Compare(Libraries.Language.Object object)
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)
Parameters
- Libraries.Language.Object: The object to compare to.
Return
integer: The Compare result, Smaller, Equal, or Larger.
Equals(Libraries.Language.Object object)
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)
Parameters
- Libraries.Language.Object: The to be compared.
Return
boolean: True if the hash codes are equal and false if they are not equal.
GetCurrent()
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
Return
number: a number representing the current, in amps, coming from the batteries.
GetHashCode()
This action gets the hash code for an object.
Example Code
Object o
integer hash = o:GetHashCode()
Return
integer: The integer hash code of the object.
GetVoltage()
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."
Return
number: a number representing the total voltage, in volts, coming from the batteries.
