Arduino Robot: #include <Wire.h> not Compiling

[yeti5]

Including the libraries like:

# include <Wire.h>
# include <ArduinoRobot.h>

gives "Error compiling"

stating: " multiple definition of `TwoWire::TwoWire()' ".

If you delete the Folder "Wire" from "C:\Program Files (x86)\Arduino\hardware\arduino\avr\libraries" it is Compiling and running correct.
This Issue is present in IDE 1.05 and 1.54

The ArduinoRobot already include a variant of the Wire library optimized for the robot.

You should remove the #include <Wire.h> line from your sketch to avoid including the library twice (the one bundled in the ArduinoRobot lib and the real Wire lib).

@cmaglie, the problem is that if you don't include Wire.h in the main sketch, you can't actually use the Wire functions in the sketch.

Note that this is essentially a duplicate of #1709, which contains a bit more analysis. That issue talks about SPI instead of Wire, but the cause and effects of the problem are exactly the same.

Fixed in 1.5.6
