Plasma arc cutting is a complex process with substantial interaction between process parameters. These manifest in deviations in the properties of the cut such as kerf width and kerf angle. Developing relationships between process parameters and aspects of the cut requires a large amount of data. This paper presents a novel method that applies computer vision to assess the kerf width against plasma...
This paper presents an improved anti-falling tree climbing mechanism. A study and comparison was made on an original tree climbing robotic system published in reference. This optimized robotic system only relies on one stepper to achieve the anti-falling and anti-jamming functionality under either static or dynamic situations. This improved design feature reduces the total robot weight and enhances...
Reformer tube is a kind of pressure vessel working under high temperature. It is a major and expensive component in chemical process industry especially in oil and gas industry. Each reformer tube costs over thousands of dollars. A reformer furnace could contain hundreds of over 15-meter long vertically installed reformer tubes working under pressure up to 15 to 20 bar and temperature reaching 700...
Early myoelectric control research approaches focused on one or two degrees of freedom (DOFs). Pattern recognition has the potential to work on multiple DOFs. This paper proposes a pattern recognition method for real-time myoelectric control system. The work presented consists of EMG data acquisition, motion activity detection, data segmentation, feature extraction, dimensionality reduction, classification,...
This paper presents a mechanism of a novel tree pruning robot that is designed to climb up a tree. The unique feature of the proposed design is the passive and active anti-falling mechanism. The passive anti-falling mechanism relies on the frictional forces to overcome the robot gravity force while the active anti-falling function uses the power provided by two steppers that is able to adjust the...
This research investigates real time tilting measurement using Micro-Electro-Mechanical-system (MEMS) based inertial measurement unit (IMU). Accelerometers suffer from errors caused by external accelerations that sums to gravity and make accelerometers based tilting sensing unreliable and inaccurate. Gyroscopes can offset such drawbacks but have data drifting problems. This paper presents a study...

This paper outlines the development of a modular mobile robot platform that is designed to provide agricultural industries with improved capabilities around managing land and the plants/animals that are held on it. The system was designed to operate within a range of environmental conditions, as well as the idea of a modular system that could provide a range of capabilities while remaining small enough...
Using bio-metric signals such as muscle and neuron signals through intelligent control systems to mimic human behavior, recovery of human organ function and rehabilitation in health care or remove human beings from hard or dangerous working condition has been an active research area especially in recent decades. This research attempts to develop a cost effective bio-driving robotic system for hand...
This paper presents the development of a high speed pipe inspection robot using structured light to measure erosion inside a pipe. Several factors influencing the speed are considered and an implementation based on a field programmable gate array (FPGA) is presented. This is a low power approach that would allow the processing of the high resolution images to be done in real time on the robot, with...
The development of an image system for measuring erosion in waste water pipes is discussed focusing on the calibration of the system using non-linear optimization for tuning. The image system is based on a simple structured light approach which is complicated by the curvature of the pipe.
Health monitoring is a challenging research area. This research aims to develop a cost effective and reliable wireless sensor for collecting real-time health vital signs such as heart rate and body temperature.

The exploration of energy source often requires drilling or even deep drilling operations in the ground, typical examples are the processes to obtain crude oil and natural gas in petroleum and geothermal industries. The exploration of these energy resources involves the use of well casing. Due to the harsh working condition, defects can occur both on the inside and outside of the steel well casing...
Reformer tube is a component used in process engineering to perform chemical reactions to produce chemical products. The process involves heating a mixture of reactant and catalyst chemical inside a tube-shaped reactor at a pressure around 20 bars to encourage rapid reactions. The service life of a reformer tube is primary ended when creep damage is determined to be excessive. Due to the high cost...
The applicability of using structured lighting for measuring pipe erosion is discussed. Processing the high resolution images on an FPGA significantly reduces the data that is required to be transferred or recorded. The FPGA is able to implement the required image analysis directly on the images as they are streamed from the camera.
In the field of human health, collecting real-time data is vital. A system that can remotely monitor heart rate and body temperature is presented in this paper. The data was collected from a group of volunteers using the sensors developed by the research team to test the system. The Arduino micro-controller is programmed to transmit the data securely to a remote PC station using an XBee wireless network...
This paper presents an approach to the control of an unmanned light aircraft. The light craft has similar properties to a helicopter. It is fundamentally unstable and with highly nonlinear dynamics. A control system is required to control, compensate, and balance the craft when there is a change on load capacities, disturbances, and environmental conditions. A fuzzy logic control system based on a...
