In the summer of 2015, MegaBots – a US robotics collective – challenged Japan’s Suidobashi Heavy Industry to a fight using giant mecha robots. The robot rumble was broadcast on 17 October 2017 and saw Suidobashi’s 4-m-tall (13‑ft) Kuratas – the largest mecha robot controlled by smartphone – battle with MegaBots’ 4.8-m-tall (16-ft) Eagle Prime. The fight – between a total of 14.5 tonnes (16 tons) of robot – ended with Eagle Prime flooring Kuratas.
The event was staged as a publicity stunt for both giant robot companies, and was presented as an "entertainment", much in the way that WWE wrestling is. However, it revealed the potential of giant robot fighting as a spectator sport.
