About the Project

Keywords:

Ingestible robot, Capsule robot, Origami robot, Degradable robot, In-vivo robotic operations, Biomedicine

Background

Recent developments in robotics technology have led to significant progress in the realisation of ingestible capsule robots that can carry out various surgical and clinical tasks inside the body. We are developing miniature robots in the form of robotic (medicine) capsules, and their remote sensing and actuation methods through magnetic fields.

Objectives

The objectives vary depending on your background and interests, which include but are not limited to:

(For ME background/oriented student): Design, fabrication, and actuation of a capsule robot’s mechanical mechanism. The robot will use the mechanism to, for example, scissor a phantom stomach wall (A hardware-oriented project with CAD, 3D printer, laser cutter, assembly, and magnetic actuation using a coil system, etc.).

(For EE): Wireless powering and sensing of a capsule robot. Develop and implement a receiver coil and a circuit with a sensor (e.g. IR) on a capsule robot, wirelessly power them with a magnetic field and utilise the sensor. (A hardware-oriented project using PCB CAD, PCB milling machine, soldering, magnetic induction with a coil system, etc.).

Methodologies:

This project will develop an ingestible (swallowable) robot in the form of a capsule or a self-foldable origami robot that can operate inside the body, particularly in the gut or intestine. The robot will have the ability to deliver drugs and perform micro-surgery with its arms and possibly (optional) be made of biodegradable materials that can be digested and excreted from the body after use. We will use an externally applied magnetic field for driving and monitoring. The assigned student(s) will first define the required robot functionality and determine the aimed motion of the robot. The student will learn how to design a robot using CAD, build with equipment in the lab such as a 3D printer or laser cutter, test it, and summarise it in a paper.

Our group has developed a variety of origami robots, one of which is an edible origami robot [1] or an extension of the functionality of origami by allowing it to 'wear' origami on its own [2].

- Students who are able to interact with group members and work on projects.

The Research Group:

The Sheffield Microbotics Lab (SML) at the University of Sheffield is an interdisciplinary group with a focus on robotics technology, developing robots ranging in size from a few millimetres to the palm of a hand. The lab has a luxurious space of 150-metre squares, including a dedicated cleanroom and equipment for robot fabrication, and chemical and biological areas. The University of Sheffield is among the world’s top 100 universities in the QS university ranking (2022). and first in the UK for engineering research investment (HESA report 2019), with £200M funded for the UK’s flagship manufacturing research centre, Advanced Manufacturing Research Centre (AMRC).

Environment:

The environment, with an over £120k equipment investment, provides excellent conditions for the proposed research. The space is shared with the Sheffield Biomedical Robotics Lab led by Dr Dana Damian, which enables active student interaction, such as co-running journal clubs and research progress meetings. The members are also affiliated with Sheffield Robotics which is the fourth leading centre for robotics research in the UK, facilitating research collaborations.

Support and training:

Students are supervised by the supervisor once a week through one-to-one meetings. They also present a monthly progress report in the lab and receive feedback from senior members. The student will be provided with a research budget, which can be used for attending an international conference and a domestic conference during the period of the programme. The department, Automatic Control and Systems Engineering (ACSE), runs a cohort training and support for all students (e.g. PGR Symposium, seminars on scientific writing, ED&I, etc.), with structured events and support available throughout their studies.
