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 during my research at Robotics and Mechatronics, University of Twente.
The motor is driven by four cylinders using only five pneumatic lines in total. Each of the six output shafts have a positioning accuracy of 2 steps. This is a consequence of the design with shared cylinders.
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.
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.
Miniaturization of MR Safe Pneumatic Stepper Motors
Many pneumatic stepper motors, rotary engines and other pneumatic devices were developed during our research. Several were published in research papers and/or 3-D model websites. This page lists nearly all of them, alongside with the most important properties and a link to the downloadable model (if available). If a motor design is not yet downloadable then you can send me a request for it.
Certain motors have extensive printing and assembly instructions and/or a video compilation. If you are interested in 3-D printing one of these motors then there should be plenty of information and designs to start with.
At the moment I subdivided the motors into five categories: linear, rotational, curved, rotary engine and dual. The motor name consists of a character (or two in case of dual-speed) plus a number and sometimes a postfix.
First character(s): T=linear, R=rotational, C=curved, D=dual. The following number indicates the major dimension (length or diameter) of the motor, in mm. The “B” postfix indicates a redesign of an existing model.
In theory it is possible to scale any design along (some combination of) its axes. This should work with some experimentation.
If you need help with a motor then you can post a comment on the associated Thingiverse or MyMiniFactory webpage, and I will look into it. You can also contact me directly at email@example.com. If you designed something cool based on these designs then I am always happy to see it!
