Project Title:    Proton Precession Magnetometer/Gradiometer
Course Suitability: BE/BSc

Background:

The PPM is a measuring instrument that can be used for precise measurement of weak magnetic fields. The instrument is based on the spin of protons in a magnetic field which is given by the Larmour equation.

Math1

Where ω is the angular frequency of precession; γ is the gyromagnetic constant and B is the magnetic field. Typically, a sensor bottle containing a fluid with a large number of protons (such as kerosene or distilled water) is subjected to a large DC current in a coil wound around the bottle. The current creates a corresponding induced field in a direction perpendicular to the earth’s magnetic field. The current is then shut-off and the protons precess with a frequency that is linearly proportional to B.

The Project:

The student will design and build a PPM instrument; the instrument will be capable of reading the Earth’s magnetic field.

The Requirements:

This is a challenging mixed analogue and digital electronics project.

Some simple physical hardware to be constructed.

Project Title:    Short Length Parametrically-Driven Foucault Pendulum
Course Suitability: BE/BSc

Background:

The Foucault pendulum, named after the French physicist Léon Foucault, is a simple device conceived as an experiment to demonstrate the rotation of the Earth. While it had long been known that the Earth rotates, the introduction of the Foucault pendulum in 1851 was the first simple proof of the rotation in an easy-to-see experiment.

The Project:

The student will construct an experimental parametric-drive and suspension for a short length (<1 m) Foucault pendulum and measure its performance. The difficulty with Foucault pendulums of short length relates to the fact that their precession is adversely affected by a range of parameters that grow more severe as the length of the pendulum is reduced. The student will investigate a range of potential suspension and drive configurations

The Requirements:

This is a challenging mixed analogue and digital electronics project.

Some challenging physical hardware to be constructed.

Project Title:    Particle Image Velocimetry (PIV) – Optimising Existing Experimental Rig
Course Suitability: BE/BSc

Background:

Particle image velocimetry (PIV) is an optical method of flow visualization used in education and research. It is used to obtain instantaneous velocity measurements and related properties in fluids. The fluid is seeded with tracer particles which, for sufficiently small particles, are assumed to faithfully follow the flow dynamics (the degree to which the particles faithfully follow the flow is represented by the Stokes number). The fluid with entrained particles is illuminated so that particles are visible. The motion of the seeding particles is used to calculate speed and direction (the velocity field) of the flow being studied.

The Project:

The student will develop an end-to-end solution for taking PIV measurements using a high-speed camera and laser. The existing experimental set-up is not well-suited to PIV investigations of flow in stirred tanks and is yielding unsatisfactory results. The existing laser and high-speed camera system is of high quality and it is desired to optimise it for PIV.

The Requirements:

This is a challenging digital electronics, software and optical hardware project.

Existing physical hardware to be configured.

MATLAB Image Acquisition and Processing.

Project Title: UAV Ground station development
Course Suitability: BE ECE Robotics, Electronics, General

Project Description:

UAV Ground station development (in conjunction with MMRRRC project – MORUS), development of a rugged, portable,   high IP rated (~IP66+) ground station control unit for control of UAVs. The ground station will interface to ground based communications systems and provide the command link to the UAV. High resolution (sunlight readable) displays, and user input devices, joysticks, keypads, roller ball will be integrated while maintaining the specified IP rating. Control station may be required to float in water (tbc). The project will have an electronics component: PCB layout and printing of various UAV boards, which have been prototyped to date. Power boards, control boards, sensor boards. Addition of built in test and fault detection circuits.

Project Title: Small Low Cost Mini ROV and Interfaces

Course Suitability:

BE ECE – Robotics, Electronics, General

Project Description:

The project is to build a small remotely operated vehicle from a build kit that is available online, known as OpenROV. The OpenROV vehicle is a low-cost underwater robot for exploration and education. The student will develop a graphical user interface for the ROV and develop tools that will aid the ROV in subsea survey operations. To this end the student can make use of expertise within the Mobile & Marine Robotics Research Centre at UL and also through the online OpenROV community of professional and amateur ocean explorers and technologists. Once completed, the ROV will be demonstrated in a local quarry to depths of 30m+ and there may also be some possibility of offshore trials.
