Finite element-based optimisation of an elastomeric honeycomb for impact mitigation in helmet liners (2021)
Journal Article

Finite element simulation was used to analyse the response of an elastomeric pre-buckled honeycomb structure under impact loading, to establish its suitability for use in helmet liners. A finite element-based optimisation was performed using a search... Read More about Finite element-based optimisation of an elastomeric honeycomb for impact mitigation in helmet liners.

A robust machine learning framework for diabetes prediction (2021)
Presentation / Conference Contribution

Diabetes mellitus is a metabolic disorder characterized by hyperglycemia which results from the inadequacy of the body to secret and responds to insulin. If not properly managed or diagnosed on time, diabetes can pose a risk to vital body organs such... Read More about A robust machine learning framework for diabetes prediction.

Evaluation of LiDAR Inertial Odometry method with 3D LiDAR-based sensor pack (2021)
Presentation / Conference Contribution

As the 4th industrial revolution emerges at the forefront of South Africa's national strategy, research areas like mapping and localization find importance in more fields than just robotics. The mining industry is well-positioned to be a potential be... Read More about Evaluation of LiDAR Inertial Odometry method with 3D LiDAR-based sensor pack.

Identification and U-control of a state-space system with time-delay (2021)
Journal Article

This article presents a state-space model with time-delay to map the relationship between known input-output data for discrete systems. For the given input-output data, a model identification algorithm combining parameter estimation and state estimat...

A new perspective on robot ethics through investigating human–robot interactions with older adults (2021)
Journal Article

This work explored the use of human–robot interaction research to investigate robot ethics. A longitudinal human–robot interaction study was conducted with self-reported healthy older adults to determine whether expression of artificial emotions by a...

Iterative learning-based robotic controller with prescribed human-robot interaction force (2021)
Journal Article

In this article, an iterative-learning-based robotic controller is developed, which aims at providing a prescribed assistance or resistance force to the human user. In the proposed controller, the characteristic parameter of the human upper limb move... Read More about Iterative learning-based robotic controller with prescribed human-robot interaction force.

Environmental analysis and optimisation of an in-orbit shape memory alloy deployment mechanism (2021)
Presentation / Conference Contribution

This study presents the analysis and optimisation of a novel deployment mechanism that utilises the shape memory effect inherent in Nickel-Titanium alloys, namely Nitinol. The mechanism is currently designed to secure and deploy solar panels on board... Read More about Environmental analysis and optimisation of an in-orbit shape memory alloy deployment mechanism.
