Comments and General Information:
Junk never competed because, quite frankly, I didn't think it would win. It had powerful servos (that were used in three later robots) and a decent scoop, but terrible balance. At a PARTS meeting, I placed it in a mini sumo ring next to a robot name Goliath. Junk immediately saw Goliath and attacked—at which point it drove up Goliath's scoop and tipped over backwards. I decided to redesign it after that. It later become the robot Just Big Boned, which ironically couldn't even compete! Junk now exists only as a bare lego frame, glued together forever and serving as a test dummy for newer robots. It was named for its junky appearance.
