USA challenges Japan to a giant robot battle
8 July 2015 Last updated at 00:06 BST
Last year MegaBot USA raised $1.8m (£1.17m) through a Kickstarter campaign to fund its giant robot vision.
Now the same company wants to create a giant humanoid robot tournament and last week challenged, the world's only other giant robot maker, Japan's Kuratas Mecha to join in.
The founder Kogoro Kurata accepted the challenge in a video this week. The battle is to commence some time next year.
Each robot suit will be piloted by a team and both are laden with guns that can shoot paint-filled cannonballs.
