This page describes the robots we have built for research in agriculture
Mantis and Shrimp
General purpose perception research ground vehicles.
Used across our industry projects in defence, mining, and agriculture
Flexible platforms allow rapid deployment in new environments, then we can do the research back in the lab to work out what lower cost sub-set of sensing and equipment can be used to build an industry / application specific prototype
In addition to the sensors seen below, we have added a soil conductivity sensor (dragged behind Shrimp), a natural gamma radiation sensor (also to measure soil properties) and recently a hyperspectral imaging sensor.
The Veggie Bot
The Veggie Bot will transform the way we monitor and harvest vegetables in a broad-acre setting. The project is in collaboration with Horticulture Australia and AusVeg.
The mobile ground robot and supporting intelligent software will have the capability of conducting autonomous farm sensing and manipulation tasks for various vegetable crop varieties. These will include mapping, classification, detection, weeding and ultimately harvesting.
The robot is a lightweight omni-directional electric vehicle, inspired by the Coccinellidae (Ladybird). It will be equipped with sensing, manipulation, communication and supporting hardware and software. Various user interfaces will also be developed for the growers, contractors and harvesters, so that they can control the robot and use the information derived from the system.
The system is currently being developed, with field testing scheduled to begin during late April to early May 2014.
Coming soon... a new robot for the dairy industry.
Large area remote sensing unmanned aerial vehicle (UAV).
Used across our projects in weed detection.
The UAV has a downward pointing camera with resolution of 1024 by 768 pixels. The field of view is 28 by 22 degrees, and the sample rate is at 3.75 Hz.
Fixed wing aircraft generally have higher payload capacity, longer flight duration and are able to cover larger distances than hovering platforms. The J3 Cub is useful for large area surveys, and is able to provide 'satellite style' imagery at a much higher resolution and lower cost than is possible from space. Using photogrammetry techniques it is also possible to map the terrain, and the combined terrain estimates and imagery are useful for many agricultural survey applications.
Unmanned aerial vehicles (UAVs) for remote sensing and interaction.
Hovering platforms typically have a smaller payload carrying capacity than the larger, faster, fixed wing aircraft, however, they are able to get much closer to the ground and to fly at lower speeds or hover. They are suited to ultra high resolution scanning and targeted surveys, and even for interaction with the environment such as targeted spraying. For example, we are able to use the onboard cameras to automatically identify weeds and then automatically target the spray.
We have several different hovering platforms, with a variety of sensors and spray capabilities.
