The United States' Transformers-like mega robot will be facing a Japanese android in a battle later this year, but the machine has already received criticism for its design. MegaBot Mark II was completed in summer 2015 and can reportedly throw objects weighing 3 pounds at speed over 130 miles per hour. MegaBot's developers then challenged the world's only other giant piloted robot named Kuratas, to a duel.

MegaBots is an Oakland, California startup company that developed the US robot, according to ZDNet. It hopes that robot fighting will become a televised sport, although the small number of fighting robots is a big problem. 

The huge MegaBot was scheduled to take on a fleet of racing drones last weekend at Consumer Electronics Show (CES) 2016. However, the event was cancelled at the last minute.

The event's format was unclear. ZDNet suggests that Mark II mighthave shot Nerf ball-like objects from its cannon. Meanwhile, the drones could fly around the big robot like planes in "King Kong" movies.

Instead of seeing a robot war, CES guests watched a demo of Mark II destroying boxes. The event spotlighted the fact that robot sports is in its early stages. However, live sports entertainment has $17 billion in yearly revenue in the U.S. alone, so robotbattlescould become quite lucrative.

MegaBots raised $500,000 during a Kickstarter crowdfunding campaign last year to build Mark II. It then challenged the 8,000-pound fighting robot Kuratas to a duel.  

The new American robot is 15 feet tall, weighs 12,000 pounds, and is the country's first-ever giant piloted mechanical robot, according to Mirror. Meanwhile, Kuratas was built by Japanese group Suidobashi Heavy Industries.

MegaBot's YouTube video has drawn much criticism. Many viewers believe the U.S. robot will surely lose to the Japanese bot.

For example, one YouTube user wrote that the machine is too top-heavy. They argued that it could easily get knocked over in a battle with the Japanese robot.

Meanwhile, the Japanese team judged that the American robot was just big. It claimed it wanted to punch and knock down the U.S. bot.

The MegaBot debut video was posted in 2015. It has now had over 292,700 YouTube views.
