It is a challenge for mobile robots to climb a vertical wall primarily due to requirements for reliable locomotion, high manoeuvrability, and robust and efficient attachment and detachment. Such robots have immense potential to automate tasks which are currently accomplished manually, offering an extra degree of human safety in a cost effective manner. In(More)
The conventional cervical joint position error (JPE) test has been used as a measure of cervical afferent dysfunction in people with neck pain. However, head movement during the test may also stimulate the vestibular system. This study's objective is to investigate the effect of the modified JPE test with a neck torsion manoeuvre in order to determine if(More)
Tissue engineering is a rapidly growing field with the aim of developing replacement tissues and organs for patients. An important aspect to the success of regenerated tissue is in the seeding of cells into structured porous scaffolds. This paper reports on an integrated system that is capable of printing bio-scaffold structures and automating the process(More)
This paper discusses an experimental comparison of three user interface techniques for interaction with a mobile robot located remotely from the user. A typical means of operating a robot in such a situation is to teleoperate the robot using visual cues from a camera that displays the robot's view of its work environment. However, the operator often has a(More)
—Modelling and control of gas turbines (GTs) have always been a controversial issue because of the complex dynamics of these kinds of equipment. Considerable research activities have been carried out so far in this field in order to disclose the secrets behind the nonlinear behaviour of these systems. Although the results of the research in this area have(More)
A method for offline system identification to model the attitude dynamics of an unmanned helicopter using neural network techniques has been developed. The processed test data obtained from various test flights were used to train a neural network ARX (autoregressive structure with extra inputs) using Levenberg-Marquardt computation. An optimised network(More)
The ability for a bio-operator to utilise a haptic device to manipulate a microrobot for intracellular injection offers immense benefits. One significant benefit is for the bio-operator to receive haptic guidance while performing the injection process. In order to address this, this paper investigates the use of haptic virtual fixtures for cell injection(More)
