A battle of the bots took place Monday at Brooklyn Navy Yard as college students put their creations to the test.

It was all part of the third-annual Mechatronics Competition, displaying the work of 40 engineering and tech students from the CUNY College of Technology.

Creations included a 3D-printed car and a robotic arm that one day could remove bombs in war zones.

The winning team received a 3D-printed trophy.
