🎉We can now proudly present the winners of the TAPAS Community Challenge 2018! 🎉
Congratulations to Team "Wireless Charging" (idea 56). We are really excited for all finalists and a really big thank you to all participants for your interest in this challenge!

We got over 200 submissions! 65 ideas got one or more TAPAS boards, 10 submissions were presentation-ready.
And now we have 5 finalists! YEAH 😃 The finalist's idea numbers were 40, 56, 68, 212 and 213.
What's next?
We are now preparing the next steps for you, the community. Please stay tuned!
We are working on a forum and a separate webpage. If you have any question please don't hesitate to contact us via email!

Move magnetic objects inside the human body by external magnetic fields

Modern medical procedures replace open surgery by the use of endoscopes and catheters. These are manually pushed from outside, while their flexible heads are mechanically by wires, manually operated. Small “USB endoscopes” are easily available at very low cost. Permanent magnets can be attached to such devices easily. With the TAPAS boards we want to test a coil scheme, where a magnetic field is used to align/orientate and move such small permanent magnets.

As shown in literature, a rotatable head on the endoscope with a magnetic moment can be rotated by slowly alternating external fields. If the head has a screw-like outer shape, it can be propelled ie. in a rubber tube, simulating tissue. We plan to develop a measurement and a feedback to ensure that the head is rotating with 3 axis Hall modules. This would result in a servo-motor like “driver” for endoscopes or catheters.

These tests will be done in a ~1:8 small-scale demonstrator on “hobby scale”. The device has 6 independent powered Helmholtz-coils in 3 axes. According to our calculations currents of 5 to 15A are needed for the proposed application in this scale. Powering the coils by TAPAS boards will allow concentrating on the development of feedback and intuitive steering systems with the sub-scale demonstrator.

We are a team of 3 people Dr. Asim Araz, Dr. Martin Bräuer, Klaus Hörcher and will conduct this project as a team outside our professional affiliation.

    Hey Martin,
    great idea! Our TAPAS team will contact you regarding a free TAPAS board shortly.
    PS: Please don't do harm to living objects ;-)

    Hi Martin,

    how is it going? Were the additional boards helpful?
    We are really curious about some pictures and more details about the ongoing progress.
    Here is just a friendly reminder that submission deadline for your presentation is on 24th of June. :-) We are excited to see your progress! 
    Please post the progress within your idea board submission.

    PS: We want to do a community call with you! Please use our doodle to find a date which fits best for you. :-)

    Hi Martin,

    Don't forget that the submission deadline for your presentation is on 24th of June! We are already curious to see the results of your project :-) Keep in mind that you still have time to work on the implementation of your idea after the submission!

    Please post your project visualization and all related documents within your idea board entry :-)
