Collision avoidance and assistance for powered wheelchairs and vehicles
PhDs and postgraduate research
Self-funded PhD students only
Mechanical and Design Engineering
Applications accepted all year round
Applications are invited for a self-funded, 3 year full-time or 6 year part-time PhD project. The PhD will be based in the School of Mechanical and Design Engineering and will be supervised by Dr David Sanders and Dr Giles Tewkesbury.
Research will be based on years of work by the Systems Engineering Research Group into robots and automated guided vehicles and will support an EPSRC project and funding coming on stream in January 2019.
Various analogue input devices and sensors have been created to safely detect the environment to assist children with different disabilities, including analogue veer-correction systems. These analogue systems have been featured on tv and radio and footage of the older systems and some of the latest systems can be seen here.
The analogue systems have been used in schools and institutions and have made a significant and positive impact and more than 2,000 people have directly benefited. The work is being hampered by the analogue nature of the systems and so this bursary will digitise the analogue input devices and object-proximity-sensors.
Main aim of the project
To create new systems to improve mobility and quality of life for people with Disabilities.
Digitise systems, investigate novel AI, and create new digital systems to assist wheelchair users to steer their powered wheelchairs in cluttered environments.
Analogue input devices will be digitized and digital veer-correction will be introduced. New digital switches will be interfaced to microcontrollers to improve mobility and manoeuvring and make wheelchairs easier for children to use. Further developments will attempted to tolerate involuntary movements and provide proportional-response controls. Collision avoidance devices will be redesigned as digital systems and connected to expert systems to interpret hand movements and tremors, and AI systems will be created to improve control. Infra-red optical detectors with background suppression will be investigated to see if they can help drivers lacking spatial awareness.
Logical IF THEN programs will be written to interpret input and then Fuzzy Systems will be investigated to see if they can be successfully used to interpret useful hand movements among tremors to control a powered wheelchair. Finally a Rule Based System will generate revised instructions for veer-correction. A novel overall Decision Making System (DMS) will compare the outputs from the three AI systems described above and will suggest the best possible course of action for the wheelchair. Case Based Reasoning (CBR) will provide confidence weightings for the different AI outputs so that the DMS can select a particular output.
The CBR will be revised to compare errors against search criteria and to then normalise those errors with weighting factors to investigate if that improves the result.

*This is the 2020/21 UK Research and Innovation (UKRI) maximum studentship fee; this fee will increase to the 2021/22 UKRI maximum studentship fee when UKRI announces this rate in Spring 2021.
Some PhD projects may include additional fees – known as bench fees – for equipment and other consumables, and these will be added to your standard tuition fee. Speak to the supervisory team during your interview about any additional fees you may have to pay. Please note, bench fees are not eligible for discounts and are non-refundable.
You'll need a good first degree from an internationally recognised university (minimum upper second class or equivalent, depending on your chosen course) or a Master’s degree in an Civil Engineering or related area. In exceptional cases, we may consider equivalent professional experience and/or Qualifications. English language proficiency at a minimum of IELTS band 6.5 with no component score below 6.0.
A good first degree and a master’s degree in engineering and computing (or similar).
