Adverse effects of invasive alien species (IAS), or biological pollution, is an increasing problem in marine coastal waters, which remains high on the environmental management agenda. All maritime countries need to assess the size of this problem and consider effective mechanisms to prevent introductions, and if necessary and where possible to monitor,(More)
78 Abstract— This paper describes a process for identifying possible grasping locations on a randomly positioned pile of clothes. For each pile, a robotic gripper is remote controlled to determine the possible grasp locations. These are highlighted on images captured from the robot’s onboard camera. Grasping points are generally edges of clothes and rarely(More)
We study a neural model of arachnid prey orientation sensing with a view to potentially using the model in Robotics. The model has been implemented using the Brian spiking neural simulator and incorporates a physics simulation of the arachnid with a simple motor model that translates sensory signals from the neural model into movement to orient towards the(More)
The interval Kalman filter is a variant of the traditional Kalman filter for systems with bounded parametric uncertainty. For such systems, modelled in terms of intervals, the interval Kalman filter provides estimates of the system state also in the form of intervals, guaranteed to contain the Kalman filter estimates of all point-valued systems contained in(More)
In this paper we analyze the problem of human facial emotion and emotion intensity levels recognition and resulting classification accuracy evaluation. Final testing set classification accuracy value is usually taken as a quantifier of method quality. However, this value is often strongly affected by the testing set parameters such as number, age and gender(More)
A robust adaptive autopilot for uninhabited surface vehicles (USV) based on a model predictive controller (MPC) is presented in this paper. The novel autopilot is capable of handling sudden changes in system dynamics. In real life situations, very often a sudden change in dynamics results in missions being aborted and the uninhabited vehicles have to be(More)
This paper describes findings from a Human-to-Human Interaction experiment that examines human communicative non-verbal facial behaviour. The aim was to develop a more comfortable and effective model of social human-robot communication. Analysis of the data revealed a strong cooccurrence between human blink production and non-verbal communicative behaviours(More)
