Whisker texture classification with uncertain contact pose geometry (2012)
Presentation / Conference Contribution

Tactile sensing can be an important source of information for robots, and texture discrimination in partic- ular is useful in object recognition and terrain identification. Whisker based tactile sensing has recently been shown to be a promising a... Read More about Whisker texture classification with uncertain contact pose geometry.

Predictive prey pursuit in a whiskered robot (2012)
Presentation / Conference Contribution

Highly active small mammals need to capture prey rapidly and with a high success rate if they are to survive. We consider the case of the Etruscan shrew, which hunts prey including crickets almost as large as itself, and relies on its whiskers (vibri...

Beyond Markov chains, towards adaptive memristor network-based music generation (2013)
Presentation / Conference Contribution

We undertook a study of the use of a memristor network for music generation, making use of the memristor's memory to go beyond the Markov hypothesis. Seed transition matrices are created and populated using memristor equations, and which are shown to...

Neuromorphic computing with memristors: Preliminary experimental results (2011)
Presentation / Conference Contribution

Individual memristors have been observed demonstrating neuron-like spiking patterns. It has been shown elsewhere that memristors provide superior modelling for neurons then the Hodgkin-Huxley model. Due to these results we expect memristors to be e... Read More about Neuromorphic computing with memristors: Preliminary experimental results.

Towards the coevolution of cellular automata controllers for chemical computing with the B-Z reaction (2007)
Presentation / Conference Contribution

Manipulating objects with gliders in cellular automata (2012)
Presentation / Conference Contribution

Micro-scale manipulation of objects is a growing requirement in specialised industries, especially those related to assembly of fragile micro-components. Widely implemented techniques in robotics and automation do not always cope with the delicate na... Read More about Manipulating objects with gliders in cellular automata.

Manipulating with excitations: Waves or gliders? (2013)
Presentation / Conference Contribution

Excitable media are classical examples of un- conventional computing devices. Using waves to represent information and wave interactions to represent information processing, excitable media achieve computation versatility comparable to traditional te...

Metachronal waves in cellular automata: Cilia-like manipulation in actuator arrays (2013)
Presentation / Conference Contribution

Paramecium is covered by cilia. It uses the cilia to swim and transport food particles to its mouth. The cilia are synchronised into a collective action by propagating membrane potential and mechan- ical properties of their underlying membrane and th...

Towards tactile sensing applied to underwater autonomous vehicles for near shore survey and de-mining (2012)
Presentation / Conference Contribution

Artificial tactile whisker sensors demonstrate an approach to localisation [1] that is robust to harsh environmental disturbances, endowing autonomous systems with the ability to operate effectively in confined, noisy and visually occluded spaces, su...

Mirror-based robotic therapy for ankle recovery with a serious game: A case study with a neurological patient (2022)
Presentation / Conference Contribution

Neuromuscular disorders, such as foot drop, severely affect the locomotor function and walking independence after a brain injury event. Mirror-based robotic therapy (MRT) has been a promising rehabilitation strategy favouring upper limb muscle streng...

Three study cases of social robotics in autism spectrum disorder treatment: Personalization and usability of CASTOR robot (2022)
Presentation / Conference Contribution

Social assistive robotics in autism has been implemented in studies and therapies to improve social skills and encourage children to comply with therapies. However, autism symptoms vary in their spectrum, which generates difficulties in implementing...

Biological indexes based reflectional asymmetry for classifying cutaneous lesions (2011)
Presentation / Conference Contribution

This paper proposes a novel reflectional asymmetry descriptor to quantize the asymmetry of the cutaneous lesions for the discrimination of malignant melanoma from benign nevi. A pigmentation elevation model of the biological indexes is first construc... Read More about Biological indexes based reflectional asymmetry for classifying cutaneous lesions.

Bio-inspired approach for long-range underwater navigation using model predictive control (2019)
Journal Article

Lots of evidence has indicated that many kinds of animals can achieve goal-oriented navigation by spatial cognition and dead reckoning. The geomagnetic field (GF) is a ubiquitous cue for navigation by these animals. Inspired by the goal-oriented navi...

Unknown dynamics estimator-based output-feedback control for nonlinear pure-feedback systems (2019)
Journal Article

Most existing adaptive control designs for nonlinear pure-feedback systems have been derived based on backstepping or dynamic surface control (DSC) methods, requiring full system states to be measurable. The neural networks (NNs) or fuzzy logic syste... Read More about Unknown dynamics estimator-based output-feedback control for nonlinear pure-feedback systems.
