Breast cancer detection through palpation requires skill in identifying subtle tissue abnormalities. Current training methods rely on physical models or live patients, limiting accessibility. A mid-air haptic device provides realistic, repeatable training in a virtual environment, simulating the feel of breast tissue for palpation. However, precise modelling and control of electromagnetic forces remain challenges that this project will address.
The intern will contribute to the development and validation of a midair haptic system tailored for simulating breast cancer palpation.
The main objectives include:
- Model Calibration: Design and implement calibration procedures to ensure accuracy in force and torque rendering, accounting for model uncertainties and field responses.
- Real-Time Closed-Loop Current Control: Design and tune a closed-loop current controller for precise electromagnetic coil actuation.
- Experimental Validation: Experimentally validate and characterise the electromagnetic fields, forces, and torques generated by the haptic device to ensure performance accuracy and reliability.
