The teams around the competitions include engineers and professionals in robotics, and the games are—aside from being an homage to their love for science fiction—a way to hone their sills in the field. Andrew Alter, roboticist and one of the mech pilots, said the competitions are taken as ‘an engineering challenge,’ noting that while they compete, ‘Having this mix of skill levels and demographics is really great to see, as information and ideas tend to flow freely. We’re also solving practical real-world problems like being able to stream video over wifi in high-interference areas. It’s not nearly as easy as one might think.’

algorithm that sometimes needs exponential space.
