Trumpy is a robot owned by Carlin Cjud and Penelope Cjud . He's sort of a cross between Robbie the Robot and Tom Servo. T-Bots have seamless compartments which can be used for hiding weapons and the like. They also have a computer brain, so they can help their owners with their smarts.
The colored lights on T-Bot's head are his eye sensors. The colors move around his head when he's working. Those things that look like human eyes are just there for appearances. To move, T-Bot hovers or rolls on wheels. I think he's cute. :)
