Floating Walking Robot

Posted on by

It’s no secret that we love bizarre robot locomotion, so we are naturally suckers for BALLU (YouTube link, also embedded below) the Bouyancy-Assisted Lightweight Legged Unit. The project started with a simple observation — walking robots are constrained by having to hold themselves up — and removing that constraint make success much easier. Instead of walking, BALLU almost floats and uses what little net weight it does have to push against the ground.

The legs are really just sticks that bend in the middle, with motors and cables that control the bend. Lift one leg up, and the center of …read more

You May Have a Nixie Tube Clock, but Can Yours Levitate?

Posted on by

nixie tubes, electromagnets, levitation, and microcontrollers, this project has “Hackaday” written all over it!

Time Flies: Levitating Nixie Clock comes from [Tony Adams], and uses a lot of technology we’ve seen before, but in a new and interesting way. A nixie tube clock is nothing new, but using electromagnets to levitate it above a base certainly paired with inductive coupling to transmit power using no wires make this floating nixie build a real treat.

In order to achieve this feat, [Tony] used coils to wireless transmit power from the base to the floating platform that the tubes are mounted to. …read more

It’s Not a Bridge, and Not a Tunnel. Or, Maybe it’s Both?

Posted on by

The gist of the idea is to suspend an underwater tunnel from floating pontoons. By the time you finished reading that sentence, you probably already had a list of things in your head that seem to make this a terrible idea. After all, it does seem to combine the worst aspects of both underwater tunnels and bridges. But, the idea may actually be a good one, and it’s already being seriously considered in Norway.

You see, Norwegians have a fairly serious obstacle to long distance travel: fjords. The tradition way to cross a fjord is by ferry. One simply can’t …read more
