Doing scientific research is one thing, publishing and communicating the results is also very important. My scientific publications are listed here and we also created many video compilations in the different projects that I am involved in. Below is a more or less complete overview of the research videos (co-)created by me, my students and/or direct colleagues, during my research at Robotics and Mechatronics, University of Twente.
The embedded videos are now primarily hosted on YuJa. Some videos are also on my Vimeo channel (ad-free). My research group has a YouTube channel and I also have a YouTube channel myself.
Many compilations have music and/or voice-over. Most of these were composed/spoken by Tim de Man.
2025
Mamri robot compilation
Compilation: Mitchel Doets
Recording: Mitchel Doets, Vincent Groenhuis
Special thanks to: Wyger Brink
Additional MSc committee members: Kenan Niu, Stefano Stramigioli, Momen Abayazid
Hoop gear pneumatic stepper motors
Presented at ERF2025 in Stuttgart
2024
ICRA40 video: Controlling an MR Safe Robot Arm with Six Pneumatic Stepper Motors using Eight Tubes
Motorized needle tool for ultrasound-guided breast biopsy
Developed by Benjamin Meijerink for his MSc thesis.
2022
Pneumatic Turing Machine: Main compilation
Can you 3D print a Turing-complete computer which runs on pressurized air? Yes! Although the number of states and bits is somewhat limited in this prototype.
First demonstrated at European Robotic Forum 2022, Rotterdam, The Netherlands.
The 4/2-way valve component can be downloaded at Printables. More components will be published later upon request.
Pneumatic Turing Machine: Busy Beaver
Demonstrates 2-state and 3-state Busy Beaver. These are special programs for a binary Turing machine which gives the maximum possible output given the number of available states.

2021
Robot-Guided Translation of a Preoperative 3d Planning During Open-Vault Reconstruction of Craniosynostosis
Project by Anouck Pilon, Eva Koot, Rémi van der Woude, Lisanne Venix. Supervised by Vincent Groenhuis et al.
Multidisciplinair project (MDO), as part of BSc Technical Medicine.
2020
Control and design of 3D printed biopsy robot using mobile application
BSc project Mart Bluiminck, supervised by Vincent Groenhuis et al.
MURAB technical video
This video shows several steps in the workflow such as path planning, ultrasound scanning, 3D ultrasound reconstruction, biopsy planning, needle insertion and sample validation. Deformations of soft tissue are taken into account.
2019
Miniaturization of MR Safe Pneumatic Stepper Motors
Presented at IROS 2019, Macau
MURAB workflow video as demonstrated at Hamlyn Surgical Robot Challenge 2019. We also demonstrated the physical robot and clinical workflow in London.
Universal Auto-Rewind Spool Holder
Although a hobby project, a combination of this device and Sisyphus spool holder are currently used at RaM for feeding one of our multi-material 3D printers.
Pneumatic Screwdriver
A hobby project using pneumatic stepper motor technology developed at RaM.
Thingiverse link for 3D files and assembly instructions
CatchBot: A Versatile MR Safe Robotic Platform for Image-Guided Endovascular Interventions
Research primarily conducted by Mohamed E.M.K. Abdelaziz. The robot uses practically the same pneumatic stepper motors as in the Sunram 4.
2018
Pneumatic Bourke Engine
This is actually a hobby project, using pneumatic stepper motor technology developed at RaM.
3D printable parts can be downloaded here.
Pneumatic Gripper
A hobby project, again using pneumatic stepper motor technology developed at RaM.
3D printable parts can be downloaded here.
Sunram 5: An MR Safe Robotic System for Breast Biopsy.
Improvements over Sunram 4 include dual-speed motors, a biopsy gun, an emergency needle ejection feature and a curved rack for better angulation of the needle towards the breast.
Dual-speed MR Safe Pneumatic Stepper Motors
Presented at Robotics: Science and Systems (RSS) in Pittsburgh, United States
2017
Sunram 4: An MR Safe Robotic System for Breast Biopsy.
This won the “Best Video” award at Hamlyn Surgical Robot Challenge, London. Over 130 articles (in 16 languages) about this robot appeared online.
The robot has a serial kinematic chain, as opposed to a parallel kinematic chain in the previous iteration.
Visualization of breast phantom and lesions with Hololens
BSc project by Leon Klute, supervised by Vincent Groenhuis.
The needle is tracked using either a stereo camera or an NDI electromagnetic tracker (from 0:31), and visualized in the scene together with the phantom and lesion(s) using augmented reality.
2016
Sunram 3: An MR Safe Robotic System for Breast Biopsy
This robot won the “Best Design” award at Hamlyn Surgical Robot Challenge, London.
Main improvements over Sunram 2 are better motors and overall design, and somewhat larger workspace.
High-Performance Pneumatic Stepper Motors
Two linear and three rotational stepper motors are demonstrated, all 3D printed and quite powerful for its size.
Controlling the Sunram 2: An MR Safe Robotic System for Breast Biopsy
MSc project by Mohamed E.M.K. Abdelaziz, supervised by Vincent Groenhuis et al.
2015
Sunram 2: An MR Safe Robotic System for Breast Biopsy
Sunram 1: first iteration of MR safe robotic system for breast biopsy
2014
Powered Exoskeleton
Internship project at University of Canterbury, Christchurch, New Zealand
