You will be required to undertake this alternative assessment in place of your deferred coursework

component or as reassessment for your failed coursework attempt. Please note, this also includes

in class tests which are scheduled within term outside of the examination window.

This alternative assessment for 5CCE2MCT Mechatronics (2024/25 academic year) is designed to

replace the outstanding components below:

Coursework 1 (30%) – Camera gantry control system design

Alternative Assessment:

an engineering design team. The video should contain an animation of the mechanism

and an overview of the Simulink model and results.

• a 1-page written report presenting the results of your design analysis with a maximum

of 2 page of supporting figures in appendix. You should use 12pt Calibri (or alternative)

sans-serif font with 1 line spacing.

Coursework is due 4pm, Thursday 24th July 2025.

Those with approved KIPS/PAA in place please refer to communications received from the

Department (PAA Information for Engineering Assessments Period 3 – August 2025) for further

information. If you have not received this, then please contact the UG / PGT office as soon as

possible.

Submissions will not be accepted after the deadline has passed, please ensure that you leave

plenty of time to check over and upload your work. If you are unable to submit by this deadline,  Information on mitigation can be found via KA-01744 · Student Services Online

Design & Analysis of a High-Precision Flow Dispensing System

Module Instructors

You are a design engineer working for a firm that specialises in developing high-precision

dispensation systems for delivering fluid solutions for medical devices. Your manager has sent

you a parametric model of a single-axis syringe pump that was developed on a previous project.

The mechanism can move the syringe plunger relative to its body by rotating a lead screw

mechanism attached a runner.

Brief

Your manager has asked you to design a new electromechanical actuation system composed of

a geared DC motor that drives the leadscrew runner of the syringe pump shown in Figure 1.

She provided CAD components and Simulink starter models for the assembly, n.b. these files

can be downloaded from the KEATS module page in the MATLAB project archive,

syringe_pump.mlproj. She has also sent you a list of requirements that she has discussed

with the customer appended to the end of this document. The client is particularly interested in

obtaining an accurate and continuous flow from the syringe. Your manager encourages you to

use the model as a starting point and welcomes further input on how to improve the mechanical

design.

You are responsible for:

• specifying DC motor, power supply, and gearbox characteristics

• design a digital motor controller

• demonstrate the effectiveness of your design.

You are highly encouraged to brainstorm additional information about the context in which

this mechanical system is to be used.

Deliverables

• a 3-minute video recording in which you present the motor and mechanism design to

an engineering design team. The video should contain an animation of the mechanism

and an overview of the Simulink model and results.

• a 1-page written report presenting the results of your design analysis with a maximum

of 2 page of supporting figures in appendix

• a zipped folder where the project model and data can be shared with assessors.

Learning objectives

• Model the electromechanical system that actuates the gantry using a combination of

mathematical, physical and data-driven methods and critique the choice of your

modelling approach

• Specify component parameters based on a design analysis of system requirements

• Implement and tune a feedback controller to control position and speed of the

mechanism

• Test the controller design against multiple loading scenarios

• Conduct a design space study to optimise system-level performance

• Report and justify recommended design implementation

Additional resources

You are encouraged to complete laboratory exercises of weeks 22-26 to develop skills in

modelling and control of mechatronics systems.
