Spherical Continuous Isotropic Omni Drive Robot

2017-10-24T21:09:52+00:00

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

2017-10-24T21:09:55+00:00

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

2017-10-24T21:09:55+00:00

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, [...]

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

,

2017-10-24T21:09:56+00:00

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 [...]

OpenRatSLAM

OpenRatSLAM, is an open-source C++ (ROS / OpenCV) and MATLAB version of RatSLAM. RatSLAM is a robot SLAM system based on the neural processes underlying navigation in the rodent brain, in particular the hippocampus.

Reading the Play – Adaptation by Prediction

2017-10-24T21:09:50+00:00

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 [...]

RoIP Mission-Critical Communication

2017-10-24T21:09:49+00:00

RoIP or Radio over IP is Zetron's next generation network for mission-critical communication gear. For reliability IP systems can be designed for multiple redundancies, especially by spoofing Ethernet switches with ARP packets. This can allow seamless failover of voice calls over IP devices. Zetron, a subsidiary of JVC Kenwood Corporation, designs mission-critical communications solutions for public safety, transportation, utilities, and manufacturing throughout the world. They have an office in Stafford, Brisbane, Australia with [...]
