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)
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)
NASA's vision for space exploration stresses the cultivation of human‐robotic systems. Similar systems are also envisaged for a variety of hazardous earthbound applications such as urban search and rescue. Recent research has pointed out that to reduce human workload, costs, fatigue driven error and risk, intelligent robotic systems will need to be a(More)
Multiple players are involved in motor and sensory dysfunctions after spinal cord injury (SCI). Therefore, therapeutic approaches targeting these various players in the damage cascade hold considerable promise for the treatment of traumatic spinal cord injury. Soluble epoxide hydrolase (sEH) is an endogenous key enzyme in the metabolic conversion and(More)
Chainmail for catalysts: a catalyst with iron nanoparticles confined inside pea-pod-like carbon nanotubes exhibits a high activity and remarkable stability as a cathode catalyst in polymer electrolyte membrane fuel cells (PEMFC), even in presence of SO(2). The approach offers a new route to electro- and heterogeneous catalysts for harsh conditions.
Hepatocyte growth factor activator inhibitor type 2 (SPINT2), a Kunitz-type serine proteinase inhibitor, has been identified as a putative tumor suppressor gene silenced by promoter methylation. We aimed to investigate whether SPINT2 might act as an esophageal squamous cell carcinoma (ESCC) tumor suppressor gene. Four ESCC cell lines, Fifty-two ESCC tissues(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)
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)
Tissue engineering is an emerging discipline which seeks to overcome many of the limitations of current surgical approaches for the treatment of tissue and organ loss. The approach utilises patient derived biological tissue replacements. Traditional tissue engineering approaches involve the seeding of suspended single cells onto the surface of a 3D porous(More)
