We’ve observed that [Carl Bugeja] likes versatile PCBs. His most recent exploit is to make PCB-based mostly springs that mix with some magnets to make minor units that soar. We aren’t confident what sensible use these could possibly have, but they are undeniably novel and you can see them — um — jumping all around, in the video, below.
[Carl] did several experiments with the spring building and layout. You can see many of the iterations in the video clip, not all of which labored out effectively. A PCB coil in the base gets magnetized when current flows and this repels or attracts the magnets at the other conclusion of the spring. What can you do with a PCB spring? We aren’t absolutely sure. It’s possible this is how your following microrobot could climb stairs?
Introducing stiffeners manufactured springs also stiff for the electromagnet to appeal to. We questioned if a various coil style at the base might be a lot more powerful. For that subject, you might not have to use a flat PCB coil in that posture if you had been truly wanting to optimize the jumping actions.
Usually, when we are examining in with [Carl] he is producing PCB-dependent motors. Or, from time to time, he’s generating PCB heaters for reflow soldering. We have noticed jumping robots, prior to, of study course. we will say the magnets seem to be fewer intense than making use of compressed air.
