Stewart Platform Wields Magic Fingers To Massage Your Scalp

[ad_1]

Notice Hackaday editors: We on the crafting crew hereby formally request spending budget allocation for putting in a Stewart system head massager on the chair of just about every workstation in the top secret underground writer’s bunker. We think the positive aspects that will accrue thanks to lessened strain on your own will much more than justify the modest upfront charges. Thank you for your consideration.

Alright, maybe that request is likely nowhere, but having been on the obtaining finish of these surprisingly enjoyable springy scalp stimulators, we can see where [David McDaid] was likely with this task. As he evidently states up front, this is a ridiculously around-engineered way to get your scratchies on, but there’s quite minimal not to adore about it. Stewart platforms, which can position a surface with six degrees of liberty and range in dimensions from very simple ball balancers to full-blown motion simulators, are interesting equipment, and we simply cannot think of a much better way to discover about them than by setting up a single.

Like all Stewart platforms, [David]’s is mechanically simple but kinematically sophisticated, and he normally takes terrific pains to determine out all the math and make clear it in an approachable type. The gadget is mounted with the finish-effector pointed down, allowing for the supposed massagee to insert their noggin into the enterprise finish and acquire the therapeutic massage sample of their choice. Hunting at the GIFs underneath, it’s easy to see why [David] favors the additional complexity of a Stewart, which can make fascinating styles like “The Calmer” doable. They are all intriguing, though the much less claimed about “The Neck Breaker” the superior, we’d say.

Hats off (lol) to [David] for this unnecessary advanced but entertaining build.
