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.

The alternative assessment is due to be released on Thursday 26th June
As clarified in the email sent to students in June, no extensions will be permitted.
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
(kcl.ac.uk)

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.
