Medarotch

A Medarotch (Japanese: メダロッチ), known in English as a Medawatch, is a device and later an application software used by a Medarotter to give commands to their Medarot. The name comes from a combination of Medarot and "watch" (ウォッチ).

Initially it was a wristwatch-type device, similar to what we now call a smartwatch. When you open the cover that houses the LCD and buttons on the top of the main unit, there is a slot for setting medals. Medarots can be summoned within the range where radio waves can reach satellites, etc.

Medarotches can also be used to transport the Medarot's parts instantly from another location, or customizing the parts the Medarot has equipped, view data during Robottle and is also see the menu screen items.

Starting with Medarot DS, it's basically a smartphone app.
