Kobotsu was a middleweight robot built by Team Vortex which competed in the inaugural BattleBots IQ competition in 2002.

It was a box-shaped, four-wheeled robot armed with a spinning drum on the front. It did fairly well in competition, reaching the third round of the loser's bracket and receiving an award for the best use of the IFI Control System, developed by FIRST Robotics as an educational control system for robotics students.

Kobotsu's name is the English pronunciation of the Japanese word "こぼつ", meaning "to destroy".

The team that entered Kobotsu also entered Vortex for the middleweight competition during Season 3.0.
