An "octocopter" may not sound like an important piece of research equipment.
But it was this tool that a Napier engineering student used to help Unison investigate the use of unmanned aerial vehicles (UAVs).
Napier Boys' High School old boy Joshua Haynes will be graduating from the University of Canterbury's mechanical engineering honours programme in Christchurch this Wednesday.
For his final year research and development project, he was part of a student team that investigated the flight performance of the octocopter - an aircraft with eight sets of rotating blades.
UAVs are used by some companies for inspection and repair work, but often don't perform reliably in windy conditions.
