Massachusetts Institute of Technology (MIT) are leaders in robotic research. One of their more recent projects is this set of self-assembling robotic cubes.
The cubes are able to communicate with one another and move using an inertial system, using an internal gyroscope.
In the video below we here how the ability of the cubes to jump was discovered quite by accident.
Normally I print with ABS plastic, but nylon is going to be a lot stronger. A piece like this may risk de-lamination between the layers, depending on the thickness of the part, the amount of infill specified, and a few other technical factors.
The nylon part seemed to be crazy tough. The walls are pretty thick, so it really should have plenty of strength to withstand a bit of hoovering. Perhaps I should (take it off the vacuum cleaner and) run over it in my car and see how it fares.
