Sport-utility robot

Sport Utility Robot, built in 2927, was the first polluting robot and the first successful robot to be big and sporty. Mom decided to classify it as a light truck. The design is ancestral to most modern robots, and looks like a primative version of Bender. The name "Sport Utility Robot" may be a reference to 21st century SUV's (Sport Utility Vehicles) which pollute more than sedans.

Trivia

 * The SUR seen in the Professor's flashback was allegedly one of the original designs for Bender.
