Watch a giant knife-wielding robot slice and dice a grand piano

When you combine the skills of giant-fighting-robot maker MegaBots with a YouTube star who prides herself on building bots that never do anything right, the results are both horrifying and hilarious.

Taking a break from perfecting its 6-ton, 15-foot (4.6 meter) fighting robot to battle in the upcoming Giant Robot Duel against Suidobashi Heavy Industry of Japan, MegaBots modified its fighting robot MKIII to chop anything put in front of its enormous blades.

Inspired by YouTuber Simone Giertz, who built a robot that badly chops carrots, the MegaBots team decided to make a gigantic version that can slice and dice everything in its path -- from produce to an oven.

The giant robot is 8 feet (2.4 meters) long and has 500-pound (227 kilogram) steel knives for arms. It even wears an extra large chef hat.

In the video posted to YouTube by MegaBots, Giertz pilots the giant robot remotely. She starts out by cutting vegetables before moving on to destroy much more impressive items such as an oven and even a tiki bar. As a grand finale, the crew places a grand piano on the chopping block.

Giertz also made a video that shows even more footage of her piloting the mega-knife robot.
