About me

I am particularly interested in soft robotics and manipulation, as well as human-robot collaboration and interaction.

MSc Project

Non-destructive mass estimation of Iceberg Lettuce

This project aims to develop a non-destructive mass estimation method for iceberg lettuce based on parameter estimation using the dynamic response of the plant to an input signal. Currently, in industry, the mass of an iceberg lettuce is measured destructively. A non-destructive method for mass estimation would enable measurements to be taken throughout a plant’s life to track growth.

PhD Project

Autonomous monitoring and control of crop growth as a feedback system

The project will model and control the growth of crops in an agricultural setting. The goal is to enable growers to maximise their harvest, by taking advantage of distributed sensing to optimise the use of fertilisers and of automation for crop management. The impact of the project will be the first direct application of feedback control to plant growth in an agricultural field.

Will will work through four work packages. The student will develop: (i) lettuce growth modelling as an open dynamical system, (ii) feedback control algorithms for crop optimization, (iii) distributed sensing technologies, (iv) automation for growth control. The student will take advantage of the facilities of the Department of Engineering of the University of Cambridge (Control prototyping lab, Agripods within the Observatory for Human-Machine Collaboration) and of the industry partner G’s growers (expertise, extensive databases, sensing technologies, automation).

Will’s PhD project is being carried out in collaboration with G’s Growers, with primary supervision by Dr Fulvio Forni.
