As you’ll see in the video after the break, this is quite the ranged weapon. While hasn’t run the thing quite that high, it does plenty of damage in the neighborhood of 40-80 PSI.

Propelling those darts at around 50 MPH is a 3,000 PSI air tank connected to an Arduino Pro Mini that controls the trigger and the air valves. We especially love the DIY darts that came up with, which are made from a PVC tube inside a section of pool noodle, topped off with a 3D printed piece for that distinctive orange cap. The whole thing weighs over 200 pounds and takes at least two people to move it around. The main body is made from wood, and there are a ton of 3D-printed details that make it look fantastically accurate. We have to wonder if it is technically bigger than the six-shooter, because they seem to be roughly the same scale, except that chose a much bigger model to start from. (Video, embedded below.) The Guinness people haven’t shown up yet to award, but at 12.5 feet, this baby is over twice as long as the current record holder, which belongs to former NASA mechanical engineer Mark Rober and his now-puny six-foot six-shooter.

Well, here it is: a shoe-in for the new world’s largest NERF gun. We recently saw another 6-DOF actuator design, using flexures, yet another ball-balancing hack, but if you want an actually useful Stewart platform application, checkout this pool-playing robot!Ĭontinue reading “An Interesting Circular Stewart Platform” → Posted in Misc Hacks Tagged 6-DOF, arduino pro mini, h-bridge, Stewart platform, tb6612

Obviously, the sketch running on the Arduino will give the thing a fixed motion, but add in an additional data link over that central slip-ring setup (or maybe a wireless link), and it will be much more useful.
Dice game farkle driver#
Control is courtesy of an Arduino Pro Mini, which drives the motors using a handful of Pololu TB6612 (PDF) dual H-bridge driver modules. One interesting deviation from the usual Stewart platform arrangement is the use of a central slip-ring connector to provide power, allowing the whole assembly to rotate continuously, in addition to the usual six degrees of freedom the mechanism allows. This circular arrangement is so simple that we can’t believe we haven’t come across it before. With the addition of the usual six linkages, twelve ball joints, and a few brackets, a complete platform is realised. The common end of each arm rides on the central shaft, each with its own bearing. This is a very neat mechanism comprised of six geared motors on the end of arms, engaging with a large internal gear.

Anyway, here’s an interesting implementation from the the curiously named YouTube channel (no, we can’t find the designer’s actual name) with a series of videos from a few years ago, showing the construction and operation of such a beast. Stewart platforms are pretty neat, and not seen in the wild all that often, perhaps because there aren’t a vast number of hacker-friendly applications that need quite this many degrees of freedom within such a restricted movement range.
