A beach-based rubbish cleaning robot being developed at Paraparaumu College is one of 35 finalists from around the country in the Conservation Innovation Awards.
The robot, which would have a vision mounted camera, would be able to independently pick up rubbish between the size of a bottle cap and a 3L milk bottle.
The Wall-E 2.0 project is being developed by the college's senior Robotics club students as well as its Societal, Environmental and Animal Rights Action Group (SEAR).
"This idea came about in response to the amount of rubbish that SEAR students picked up along the beach and wanted to create something which could regularly go out along our beaches and pick up the rubbish before it ended up being a contributing factor to ocean pollution," student Maha Fier said.
"Creating a robot which can regularly go out during the week and clean up the amount of litter within a beach can be revolutionary as we face issues like ocean pollution and litter.
