Urgent action needed to restore Waikato lakes' health
Waikato is home to a diverse range of lakes, and experts say they urgently need better management and restoration.
Three high-tech horticultural robots made their appearance at this year's National Fieldays at Mystery Creek.
They included a robotic asparugus harvester, an autonomous grape vine pruner and a kiwifruit orchard survey robot.
The robots are collaborative projects involving students and academics from the University of Waikato (UoW) School of Engineering and the School of Computing and the Mathematical Sciences, in partnership with other academic institutions and businesses.
"Agritech is very important to solving problems," says Dr Shen Hin Lim, senior lecturer in mechatronics and mechanical engineering at UoW and chair of NZ Robotics Automation and Sensing (NZRAS).
"New Zealand is considered a world leader in agricultural innovation, and I believe that we can demonstrate that and have an edge using ag robots," he told Hort News.
Ag robots support the horticulture sector in a number of ways, automating some time-consuming tasks, enabling people to get on with other work and offering a sustainable solution to labour shortages.
Technology also helps the agricultural industry to maintain high productivity, ensure safe, high quality food products and minimise its environmental footprint.
Lim leads the team who developed an asparagus harvester which was on display at the Innovation Hub. The fully operational prototype was developed with the support of Callaghan Innovation, in collaboration with Robotics Plus Limited.
The asparagus harvester has a high-tech vision system that detects the asparagus spears, computes their base location, and if it detects that the spear is tall enough to harvest, uses a robotic arm to cut it as the robot passes over.
Another innovative robot is the MaaraTech Grape Vine Pruner, a transdisciplinary codesign project funded by the Ministry of Business, Innovation & Employment (MBIE), including researchers from UoW, Robotics Plus, the University of Auckland, the University of Canterbury, Lincoln Agritech, University of Otago and Plant & Food Research.
Auckland University holds the contract for the five-year MaaraTech project, and UoW is subcontracted to focus on the hardware development and physical aspects of creating the technology.
Dr Benjamin McGuinness, a research and teaching fellow in mechanical engineering at UoW, says the robot’s cutting blade - dubbed “the barracuda” - has evolved over many iterations and modifications of commercial secateurs.
Its innovative design helps ensure wires are not cut by mistake.
“The design we’ve come up with has a series of slots in the anvil of the bottom blade. The idea is, the wire will fall into the slots but the cane is too big to fit in there, so the blade will cut the cane,” says McGuinness.
The Orchard Survey Robot was funded by Zespri to advance innovation and research in the kiwifruit industry, to benefit growers.
It uses a variety of sensors to autonomously navigate around the orchard to capture information that can provide actionable insights to growers, says Nick Pickering, a systems engineering lecturer at UoW, who is leading the project.
It can be programmed to capture a wide range of data through the life cycle of kiwifruit growing.
“We’ll be initiating the research later in the year starting with flower counting and canopy cover, with plans to expand the collaboration into the areas of pest and disease detection, fruit estimation and plant structure,” says Pickering.
“The information from the robot will be used to support growers to make complex decisions to optimise fruit quality and quantity.”
According to the most recent Rabobank Rural Confidence Survey, farmer confidence has inched higher, reaching its second highest reading in the last decade.
From 1 October, new livestock movement restrictions will be introduced in parts of Central Otago dealing with infected possums spreading bovine TB to livestock.
Phoebe Scherer, a technical manager from the Bay of Plenty, has won the 2025 Young Grower of the Year national title.
The Fencing Contractors Association of New Zealand (FCANZ) celebrated the best of the best at the 2025 Fencing Industry Awards, providing the opportunity to honour both rising talent and industry stalwarts.
Award-winning boutique cheese company, Cranky Goat Ltd has gone into voluntary liquidation.
As an independent review of the National Pest Management Plan for TB finds the goal of complete eradication by 2055 is still valide, feedback is being sought on how to finish the job.
