Stingrays have an elegant, undulating swimming motion that can be hypnotic. [Vimal Patel] re-created this harmony with his fantastic mechanical mechanical stingray using LEGO pieces and a LEGO Technics Power Functions motor. The motor is set in a clever arrangement that drives the motion remotely, so that it and electrical elements can stay dry.
The mechanical stingray sits at the end of a sort of rigid umbilical shaft. This shaft connects the moving parts to the electrical elements, which float safely on the surface. This leaves only the stingray itself with its complex linkages free to move in the water, while everything else stays above the waterline.
We’ve seen some impressive LEGO creations before, like this race car simulator and pneumatic engine, and the mechanical action in this stingray is no exception. Interested in making your own? The part list and build directions are available online, and you can see it in action in the video embedded below.
Love it! It looks so cool swimming along.
I thought it looked like it was wounded.
Having a harpoon stuck on your back tends to have that effect ;)
Must say that this is very impressive, look and motion pattern is way better then i thought possible given the size and hat it was built with LEGO. Would love to see some better above water video, to better see the construction and motion.
I mean the video is nearly a decade old. I guess someone attempted to further improve on that idea :)
