Welcome! I am Vincent Groenhuis and assistant professor at the group of Robotics and Mechatronics, University of Twente. I completed my BSc in Computer Science (with 2nd propedeuse in Applied Physics), my MSc in Embedded Systems and my PhD in medical robotics, all cum laude and at University of Twente.
My research primarily focuses on MRI-guided breast biopsy (Sunram/Mamri projects) which we actuate by our novel 3D printed pneumatic stepper motors.
I also give four courses. In 2025-2026: Q1: Modeling & Control (module M5A Smart Technology, for 2nd year CreaTe). Q2: Model-based Control for Robotics (module CPS, for Computer Science). Q3: Introduction to Physical Systems (module M3, for 1st year CreaTe). Q4: Embedded Systems Laboratory (MSc course ESYS).
I also supervise individual students for their BSc, MSc, individual and/or internship projects. Contact me if you are interested in doing a (medical) robotics or pneumatic (stepper) motor-related project with me.

My research focuses on medical robotics and stepper motor technology. Technological advances could improve diagnosis and treatment of e.g. cancer in the breast of bladder, while innovative pneumatic and electric stepper motors offer new ways of actuating various applications.
Sunram is an MRI-guided robotic system for breast biopsy. Being operated by pneumatic stepper motors it is safe to use inside an MRI scanner. The fifth generation is Sunram 5 (video), while new prototypes are being developed regularly.
The Next-gen in-vivo project focuses on bladder cancer diagnostics using a robotically-steered instrument with an optical coherence tomography sensor in its tip. In this project I primarily focus on the imaging side
Multi-axis electric stepper motors offer an innovative way of actuating multiple degrees of freedom using a singular stator which drives multiple rotors simultaneously (video), while sensorless absolute encoder motor technology offer a novel way of measuring the absolute position and torque in stepper motors.
Several pneumatic stepper motor designs are open source. See https://www.vincentgroenhuis.nl/wp/home/2019/10/11/stepper-motor-overview/ for an overview of the different variants of which many are directly downloadable. Contact me (v.groenhuis@utwente.nl) for the non-published designs, and any other questions.

Research profiles
2025-2026:
Q1: Modeling & Control (module M5A Smart Technology, for 2nd year CreaTe)
Q2: Model-based Control for Robotics (module CPS, for Computer Science)
Q3: Introduction to Physical Systems (module M3, for 1st year CreaTe)

I also regularly supervise BSc/MSc/internship/project students. Mostly individually, but small groups are also possible.
Some available BSc/MSc assignments are listed on https://www.ram.eemcs.utwente.nl/education/assignments, but you can also propose an interesting idea (robotics, imaging or stepper motor related) yourself and contact me to discuss the possibilities.
