Robotics for Zero-Tillage Agriculture (AgBot)

Farmers are under growing pressure to increase production to feed a growing population, while at the same time considering environmental impact and constraints on land, water and labour. The increasingly larger farm machines cause significant soil compaction damage and are a single point of failure. Hence, in this project we developed the technology for small, inexpensive, cooperative robots for agriculture. This project was comprised of five themes: vision-based obstacle detection, vision-based [...]

Automated field testing

Seed breeding is a critical part of agriculture and ensures food security through the development of new crop varieties that are higher-yielding, disease and drought resistant and adapted for each region. Best practise is to have breeders measure and record traits across a large number of seed trials. However, it is hard to get consistent measurements across breeders especially across different regions. There are also limits to what a person [...]

iRat – Intelligent Rat animat technology

,

The iRat (intelligent Rat animat Technology) is a rat animat robot designed for robotic and neuroscience teams as a tool for studies in navigation, embodied cognition, and neuroscience research. The rat animat has capabilities comparable to the (then) popular standard Pioneer DX robots, but is an order of magnitude smaller in size and weight. The robot’s specifications are: approximately 0.08m2 with a mass of 0.5kg, camera sensor, proximity and odometry sensors, [...]

RoboRoos – Robot Soccer

The RoboRoos Robot Soccer team competed in the Small Size League of the annual RoboCup competitions. The goal of the RoboCup federation is "By the year 2050, develop a team of fully autonomous humanoid robots that can win against the human world soccer champion team."  The rules are similar to the human version of the game (FIFA), other than the elimination of the offside rule as well as modifications that accommodate [...]

Strategic Investment in Farm Robotics (SIFR)

This project is fast-tracking robotic technology for farms. Its purpose is to reinvigorate agriculture through increased production and reduced costs. Such technology can be used to conduct autonomous multi-vehicle operations in applications of weed management, fertilising, and seeding. The use of multiple, cost-effective field robots can enable alternative weed destruction methods such as mechanical, thermal or chemical. It can also enable autonomous methods for picking fruit and vegetables. The Strategic [...]

SAParm

aka Robot Arm for Video Screen Manipulation The goal of the SAParm Project was to produce a proof-of-concept robotic video conferencing system to convey gestures of a remote conference participant. It could mimic human gestures such as nodding and shaking its head; show interest or strong feeling by moving forward; and indicate disinterest by moving backwards. It also moved in a very natural way by first turning its head, followed by [...]

Skippy the robot kangaroo

 aka energy efficient legged locomotion The goal of this project was to create a new generation of legged robots that can traverse over rugged terrain in an energy-efficient manner. The team designed and tested a new energy efficient joint mechanism suitable for the robot’s knee. In particular, the joint’s stiffness can be changed on the fly so that it can cope with ground of varying hardness. We also demonstrated that [...]

Spherical Continuous Isotropic Omni Drive Robot

Robots comprised of an omni directional drive system have a distinct kinematic and mobility advantage over the standard differential drive and Ackermann (car-like) drive. In this project we designed an omni directional drive robot with very high mobility that can negotiate typical edge and gap traversal obstacles in an indoor environment. It is based on a novel spherical drive mechanism which has the advantage of continuous contact with the ground plane to reduce [...]

LingoDroids

,

Lingodroids are language learning robots that play games to construct shared lexicons. These fascinating mobile robots have learnt lexicons for places, distances, directions, and time. Our latest work demonstrates how to handle referential uncertainty, that is, how to resolve a word’s meaning between multiple candidates. Further, we have demonstrated language learning between robots that have different embodiment and cognitive capabilities. They differed in their sensors (camera images versus laser ranges); [...]

Insect environment replication

Scientists are trying to understand insect behaviour. To assist we developed a virtual world for Bees. This virtual world consisted of up to six monitors surrounding the Bee along with a controllable platform. We have a virtual display running across up to six monitors @ 1920 x 1200 @ 60 Hz. Using a Python interface the neuroscientists could configure the textures, windows, ground, camera pose, etc. A LEGO mechanism allowed the [...]

Rodent Scope – A wireless telemetry system for animals

Extracellular recordings in animals, made using wire implants within the brain, detect changes in the extracellular voltage when neurons discharge. Typically, electrophysiologists tether their rodent to their neural recording equipment which limits the range of possible experiments. In this project we designed a digital wireless neural telemetry system, Rodent Scope (RoSco), which enables new experiments such as neural recordings from rodents in large outdoor environments and social experiments. It is small, [...]

Spike Time Robotics

,

In this study a spiking network controls the iRat in real time. The study demonstrates how the neural controller directs the rat animat’s movement towards temporal stimuli of the appropriate frequency using an approach based on Braitenberg Vehicles. The circuit responds robustly after four cycles when first detecting a light pulsing at 1 Hz, and rapidly after one-to-three cycles when primed by recent experiences with the same frequency. This study [...]

Rat meets iRat

,

Rats have long since been used in a wide range of behavioral studies. This project is ongoing work to use the iRat as modeling platform for neuroscience studies, for testing neural models of bio-inspired navigation algorithms and for behavioral studies showing rat-robot interactions. Many of the rats observed the iRat, peeping over the wall to check where it was, and often tracking around behind it. Over a period of four days, five [...]

A Rat in the Browser

,

A telerobot, is a telepresence device that allows a user to interact with a robot over the internet. There are few active public telerobots on the internet. This work describes a new Internet telerobot framework suitable for autonomous mobile robots and designed for user edutainment. Users could give the robot navigation goals. The results demonstrated a reliable autonomous mobile robot system that, within 24 hours of continuous operation, reached 447 goals, traveled [...]

Reading the Play – Adaptation by Prediction

My PhD thesis project was “Reading the Play – Adaptation by Prediction”.  The basis for the approach was akin to an elite sports player being able to "read the play", allowing for decisions to be made based on predictions of likely future outcomes. Using Markov chains we could model the opponent behaviour to prediction their likely future state. This brief video shows the prediction system at work in the RoboRoo robot [...]

Blind Bayes

,

aka Maintaining a Cognitive Map in Darkness: The Need to Fuse Boundary Knowledge with Path Integration The iRat was used in one of Allen Cheung's studies to find out if animals need "cognitive maps". From the abstract: "Spatial navigation requires the processing of complex, disparate and often ambiguous sensory data. The neurocomputations underpinning this vital ability remain poorly understood. Controversy remains as to whether multimodal sensory information must be combined into [...]
