Call For Project
The self propelled rope
How might we make a rope that can pull itself through water?
If you pull a length of rope through water, you will notice that i makes resistance. A rope with minimum resistance, or one that even pulls itself, would be helpful in many rescue situations, at many scales.
This is an initial call. Shallow research has not given indication that the envisioned technology exists. Any level of work furthering the field would be appreciated, e.g.:
- Research into existing projects, technology and products
- Ideation about possible solutions
- Research and development of technologies that would make the ida possible
Pulling any length of rope through water at almost any scale presents the problem of resistance, e.g.:
- A rescuer swimming to help out with a rope â€“ wether held in a hand, clenched between the teeth, or tied to the body â€“ will notice that it is much harder than swimming unhindered
- Pulling a long rope with a small tender to a boat in shallow water in need of a tow can be demanding. If the rope is long enough and the tender boat small enough, it may even cause a capsize
- Retracting a long tow line without a without a winch can be very hard work. Better save your breath for actual rescue work!
The field is wide open.
- If power is needed, it could be supplied externally, but better yet would be self generated power, e.g. through wave motion.
- The forward motion could be generated on the surface of the rope, or maybe through a snaking motion.
- If self propulsion ends up being too tall an order, a rope with minimized resistans might also be a valuable outcome

Who is behind the project?
The self propelled rope is a project call from the Innovation office at Swedish Sea Rescue Society, SSRS. The SSRS is a non-profit organization that performs 70% of sea rescues in Sweden thanks to some 2000 volunteers . Our constitution says that â€” aside fromÂ perform sea rescue operationsÂ â€”Â we are to further the interest in sea rescue matters, and to propose ways to improve sea rescue.
The person proposing this project is me, Fredrik Falkman. Iâ€™m a trained industrial designer working for the SSRS with development projects and general innovation. Beside my work at the SSRS, I run a design consultancy:Â Fredrik Falkman Design AB, FFD.
