Crabfu is at it again! Answered

Picture of
Crabfu has made another uniquely special kind of robot.

Based on the mechanism that controls the angle of the blades of an RC helicopter, it's called SwashBot.

I'll let Crabfu explain it properly:

Is the video sped up? I am working on a similar design to yours, yet my servos are not that responsive..

(It's not my design, it's Crabfu's)

I don't think it's sped up, maybe you'd better contact Crabfu to ask (PM him, or add a comment to his YouTube video).

Oh ya, You should really sell these. Like, reeaallly. I want one You could start selling kits in the Instructables marketplace with just servos and maybe the gyro included.

Lol thanks! I need to learn how to make plastic molds etc.... I'd love to get more detail into this swash crab thing... shape lock is awesome stuff, but hard to get exact shape and detail that I wanted. If I can figure out this plastic nonsense, kits should be pretty simple. There are only 3 servos, and you just need battery, receiver, helicopter transmitter, and led lights. There are no gyros in these swashbots :) -Crabfu

The best way might be to simply make up some silicone molds and shapes and try it yourself...

Oh yeah - crabfu indeed! :-D

Great job - v2 didn't quite capture the cuteness of v1, but I think this one has just as much attitude as its little brother. The shapelock looks excellent!

OK SwashBot2 is now officially finished :) I went back to inchworm movements, as it was falling way too much, and not reliable enough when not using the body as support. Turning still works on the tips of the feet only, but walking in all directions are now back to placing the body down. Also improved the leg hinge joints and a few things here and there :)

Using two commas together switches on (or off) the subscript function. A power sign (shift 6 on my keyboard) controls superscript.

Two apostrophes make italics, three makes bold, and five...

On a new line == This is a headline ==

Like this


Pairs of tilds (? the squiggly thing, shift #) makes strike through

Might as well add the original link to Crabfu's Swashbot...

(... and if you're wondering "crabfu - where have I heard that name before", he's the one who came up with the R/C Steam Turbine Tank. Many more variants on the Steamworks part of his website...)

I really love what you make, Crabfu, keep up the good work! Do you need a really complex transmitter to make this work? I've recently bought a futaba 6 EXAS do you think it will work for this robot ? Good Job!

Select as Best AnswerUndo Best Answer

user
crabfu (author)lordofthedonuts2008-04-26

I don't think that futaba will work.... it needs to be a helicopter transmitter, eccpm. Also, since this thing is not taking off ground, you should make sure that the radio is legal for land use. I think only the 2.4ghz are land legal and are heli compatable. I quickly looked into your futaba tx and I think it's only made for a fix wing. -Crabfu

Thanks for all of the comments and pushing it for the robot contest.... I'm not sure if I will have the time to make an instructables for it right now. Besides... I live near robogames, and I already have a robophilo, perhaps the prizes should go to someone more deserving :) -Crabfu
