Let's Make Robots!

Tachikoma


The other day was talking to a friend who is animageek. She was asking: "Why don't you build a Tachikoma? It looks like doable!". Man! That's way far than what I capable of "building" robots! Think about those feet can transform to a wheel! How could that been done in nowadays? Even its transformable it won't be able to carry the weight by that kind of design; furthermore, that freaking big ass is impossible to balance a bot like that. Forget it, it's animation. But night after night, it just can't get out of my mind the possibility to build that thing. Fine! I will try to challenge it it, at least do a simple version of it. So, that's how it begins....

Found micorwaveable food covers that perfect for the body shape:

The shampoo bottle that perfect for the feet:

The used parts from Tetris perfect for "bones":

Kill my old quad-leg robot for leg:

Some cheap continues servo and wheels from eBay and modify a bit:

Find some basketballs from Toys'R'us and used pipes.

Cut holes here, fill up some holes there and sand it a bit:

Steal couple milk bottle from my wife and lego parts from neibour's kids:

I can't find better shape for that fat ass. So, cereal box is my choice:

And finally.....SPIDERS!! Perfect for multi servos machine:

Give it some color:

 


 

So far so good. Now, I am an idiot in electronic and maybe later on programming as well. I might start asking stupid questions around LMR or other forums. Please help me if you see me dying for waiting answers :P

I try to make eyeball LOOKING around and I suddently realize how diffecult to make ball spin in the air and centerize it perfectly. Look at this ugly eyeball:

It looks fine like that, but when I put inside the shell, it's not centerized well and I spend so much time(2 weeks) to figure out how to put it in proper position. And I end up give it up and just hot glue it in the shell. What a shame... I still wanna poke it out and make it "looking" around.

And here is how I connect that big ass cereal box:

Here is how I make the leg and wheel:

It's getting heavier everyday by adding this and that:

Forgot to mention I use wireless camera inside the eyeball and the antenna is the one that point out from the center of its head.

This is how it looks now in AUG,29/2011:

I try my best to use image to describe how it been build so far and hope you can understand how it work in this chassis. Please point me out where I can improved or modified. In this stage now, I am working on CLAWS and still want that eyeball able to move. Feel free to tell me all mistakes and any improvement.


8 LEDs had been added to the "S" box.

The claw from LEGO had been added too. I use a mini servo to bull all 3 claw from inside of the body.

The other hand just simply adding a laser and I don't think I will add another working claw but fake still claw in laser side. It just too complecated spacing issue to put evrything in lilmited space.

Whole chassis should be done soon and hopelly move to programming stage next week.

Aboslutely Rad! Hahahaha...I'm a huge GITS freak myself....keep it going. I'd love to see your progress continue :)

Building a Tachikoma is something I've considered doing ever since I saw GITS, but it was always too much of an ambitious build for my budget.  Looking forward to seeing how this comes out!

i like the movie of ghost in the shell.nice bot!

WAOU your robot is amazing !

I like the way you build it, a very impressive structure :)

Keep the good job :)

MoX

 

Oh, this is just so fun to see. Great job so far!

this is so ...COOOL!!

i have seen ghost in the shell well the films and i am very impressed with what you have done there. if i where you id give it to your friend n take it to a cosplay they will explode 

Great build Hardmouse!

The only way to make the eye ball move properly is to use the old mouse rolling ball system. Have the eye a bit bigger than the hole, place it from inside out so it can't fall out, and build 2 perpendicular axles that spin the ball vertical and horizontal. Each axle can be rotated by a servo for eazy control. Add some ruber tube on the axles for better grip on the eye ball.

That's sounds great!! Nice idea RobotX!!

I actually measured the spacing in the dome with your idea but its running out of space. Not enough room to fit the system. I will keep work that out. Thanks man!

I have never seen such a cool collection of plastic bottles and food containers! Can't wait for the video!
