Matches are played between red and blue robot alliances, which compete for two minutes on a field four metres by four metres. Obstacles and objects including a beachball need to be negotiated and manipulated for points.
While schools compete, they also need to work together at times. The tournament champions will go to the World Championships in Anaheim, Los Angeles this April.
There will be a bit of pressure - New Zealand has entered for the past five years and won each time.
University students mentor some teams, with Kiwibot sponsor Fisher & Paykel Healthcare guaranteeing those who do, a job interview.
Mr Hamling said the reason for that was obvious to anyone who saw the machines in action.
"You have kids that are designing pneumatic mechanisms to fire these beachballs ... from one side of the field to the other.
"There are all the various design elements, physics comes into it, and battery management is another ... there is software programming involved."
