Introduction: Inchie

Picture of Inchie

An amusing, three-legged robot named 'Inchie'. Feel free to copy or change him. I don't care if you 'republish' him. Please be patient with the movie. It takes a while to load after you click on it.

Step 1: Step 1

Picture of Step 1

Make three. These are the legs.

Step 2: Step 2

Picture of Step 2

Make the... well, I don't know what it's called. If you don't have this type of engine(yes, you need an engine for this to work) I'm sure you can figure out a way to put a different one on it.

Step 3: Step 3

Picture of Step 3

Put it all together. Attach the red connecter thingies on the thing whose name is unknown to the blue rods on the legs. Turn left for best results.(Due to the way the motor isn't balanced. You can stand it up the way I have it, or you can lay it down so the K'NEX logo on the motor faces up. It works both ways.

Hi! i made this wonderful machine but it seems my motor is unable to lift the legs and the motor is the exact same motor as yours! Please HELP!!!!!!!!!

robotmaster (author)Tmbo179322008-09-17

I dun know, all I can think of would be to try changing the batteries

Tmbo17932 (author)robotmaster2008-09-19

is by any chance the purple motor stronger or faster than what ive got wich is a grey motor?

robotmaster (author)Tmbo179322008-10-12

Oh, you have the gray motor. try my other design. The gray motor is fast, but gutless, it has no strength. the purple motor is slower, and stronger. Just click on my picture, and you can see the other model.

Tmbo17932 (author)robotmaster2008-11-07

ok. i have now got a green motor is that as strong as purple motor?

mettaurlover (author)2008-09-16

i'm gonna extend the leg turners, and use shock absorbers in the legs.

kennyboy 2 (author)2008-09-03

this is kenny boy 2 saying this is a awsome design and i have one simaler to it and i have a knex dragger that grags its self all over and i am posting them soon!!!!

very clever - simple yet effective

The Jamalam (author)2008-05-30

I built this and added a siren XD It was hilarious!

Braeburn (author)2008-05-26

oh i see how it works! Very cool! (voted)

Thanks, I've got a few other robots, do you think I should post them too?

Bartboy (author)robotmaster2008-05-15

yes , and i would just like to say it pi***s me of when people ask if they should post, just do it!

robotmaster (author)Bartboy2008-05-16

watch the language for Pete's sake

Bartboy (author)robotmaster2008-05-16

Hey! I censored it! pplus its not a swear!


Riku reborn (author)2008-05-16

HI!!!!!! I finally signed up. Cool 'bot!

robotmaster (author)Riku reborn2008-05-16

Hi Spence, love the pic.

Itsgoofytime (author)2008-05-12

You could really fix this up. You could include how many parts needed and much more through pictures.

knexguy (author)Itsgoofytime2008-05-14

Do you mean 'thorough'?

robotmaster (author)knexguy2008-05-15

I don't follow

knexguy (author)robotmaster2008-05-15

He put 'much more through' and I was asking if he meant thorough. You can tell if someone is replying to someone other than you because their comment is staggered.

robotmaster (author)Itsgoofytime2008-05-13

Well, actually, I thought that since it was a simple design it wouldn't really matter, but then again I might do just that, thanks!

I_am_Canadian (author)2008-05-13

I like it! Im not toadally sure it would qualify for the robot contest, but, well, you have my vote!

I didn't think so either, but it doesn't hurt to try, right?

Bartboy (author)robotmaster2008-05-15

If you think so...

Thats true....

ojochris (author)robotmaster2008-05-13

Hell yea!

popomaster (author)2008-05-12

u could make a tiny version =] it would rotate faster and have a little more toque as the thing gets lighter and so does the weight of the arms. that would be so cool *having an army of "inchies" more like centimeteries for the tiny ones

robotmaster (author)popomaster2008-05-13

If you want to make it smaller, it's actually quite simple, just a 'down-grading' of a few pieces. My motor doesn't really show a big difference in how fast it moves due to weight on it. If it get too loaded down it stops and 'clicks'. It either rotates or it doesn't. As for making it smaller, I've always been doing some work on it to try to improve it, I just chose to put the original one on here. This is only my first Instructable.

CameronSS (author)2008-05-12

A K'Nex device that I actually like! Well done! A video would be nice...any chance?

PKM (author)CameronSS2008-05-13

Ditto... K'nex is good for something, it seems. I agree, a video would be desirable, and maybe more thoughts on how you could extend or modify the design? I'd be tempted to call the unnamed bit a crankshaft.

robotmaster (author)PKM2008-05-13

Crankshaft it is! I don't completely understand what you mean by modify it, but I'll try to answer. I actually made one with two legs instead of three, but that's another instructable(archie). It doesn't necessarily walk, but rather wobbles. I'm still working on one that actually stands on one foot at a time. Otherwise you could put simplified guns on it, just as long as you keep it balanced.

robotmaster (author)CameronSS2008-05-13

Actually, I borrowed my sister's camera to take picures. She's been nice. I might be getting a digital camera for my birthday, so, to answer your question, yes, there is a chance
