Create a Super Robot Development Lab Program in Java.$$ Design a base class for your robots, detailing essential attributes $($like model name, power level, and pilot$).$ Implement several unique robot types, each with distinct behaviors. Introduce an upgrade feature, with exception handling for cases when upgrades aren$$t possible. Manage a team of robots with file$-$based loading, using JSON or XML for the robot data. Demonstrate these robot features, with detailed documentation on each component and functionality.

Imagine you$$re creating a model of Optimus Prime as a unique robot. First, think about essential qualities that make him distinctive$$his name, energy level, and ability to operate independently.

Optimus would also have signature skills: a powerful blast attack and a shield defense. You might add an upgrade feature, but since Optimus can$$t always go beyond his maximum power, include limits to avoid $$overcharging$$ him. For more flexibility, design a way to load specifications of the robots from a file to allow each robot to be uniquely defined without reprogramming every detail.$$ You create the file and specifications.
