Hydraulic robot made of cardboard and scotch duct tape. by Nelson_Yepez

用卡纸胶带做成的液压机械臂

译者按：印度和中国的确是神奇的国度，一个能化腐朽为神奇，另一个能化神奇为腐朽……在发散创新思维上，我们得加油啊！

I always wanted to do this project but in all the guides i always found that you need some kind of wood cutting skills and/or tools. So … I decided to make a simple hydraulic robot with cardboard, reinforce and hold by duct tape that anyone can do.
一直以来我很想做这个作品，但在所有教程当中，我发现玩家们需要木工技巧或工具才能完成。于是……我决定做一个简单的液压机械臂，只用卡纸，辅以胶带纸固定，那么男女老少都有能力去做。

Duct tape not only is strong but also looks pretty cool; it gives the robot a cool metal like look and it holds everything together really good.
胶带纸不光坚韧，同时看起来也很酷。它使得机械臂有一种冷金属感，同时它把所有东西固定得很牢。

Step 1: What you are going to need!

步骤1：你需要的东西

FOR THE BODY OF THE ROBOT:
- Cardboard box (the harder the better, I used a pizza box but you can used any type because we are going to reinforced with the duct tape)
- Scotch Duct tape (I like the silver because the metal like look)
- 3 machine screws 3 inches in size with nuts
- 2 machine screws 1 ¼ inches in size with nuts
- A flat and square piece is wood ideally 12 inches by 12 inches for the base to attach the robot
机械臂身所需材料：
- 卡纸盒子（越硬越好，我用的是个比萨盒，你用什么类型都行，因为我们会去用胶带纸固定它）
- 透明胶带纸（我喜欢银色那种，看起来像是金属）
- 3枚3英寸螺丝及螺母
- 2枚1.25英寸螺丝及螺母
- 一块平整的正方形木板，最好是12英寸乘以12英寸，用来作为机械臂的底盘。

FOR THE HYDRAULIC SYSTEM:
- 8 syringes (you can get them at any pharmacy without prescription just say you need the type that is use for cough medicine, you can’t put a needle on those. I got mines at CVS and Walgreens for free)
- 6 feet of clear tubing ¼ “x .170” (got mine at home depot for $3)
- Water
液压系统的材料：
- 8管注射器（无需医生处方，在各大药房有售。跟工作人员说是用来吸咳药水那种的就行，反正也装不上针头。我在CVS和Walgreens免费就能得到。）（译者注：在中国，还是直接淘宝吧。只是，印度的医保不是一般的好，针筒都能免费拿到。）
- 6英尺长透明软管，0.25英寸外径，0.17英寸内径。（我在日用品店里花3美金买到）
- 水

TOOLS:
- Scissor
- Ruler
- Pen
- Drill
工具：
- 剪刀
- 尺子
- 笔
- 钻子

Step 2: Draw the template

步骤2：画模板

Now draw the template on the cardboard, these are the measures that I used but you can change them to make a smaller or bigger robot.
现在在卡纸上画出模板。这里说的是我画的尺寸，但你能改变它们的尺寸，做成小一些或大一些的机械臂。

From the template cut out:
2 x A piece
2 X B piece
2 x C piece
2 x D piece
1 x E piece
如图所示，模板的分配如下：
A部分2个，B部分2个，C部分2个，D部分2个，E部分1个。

These are the main parts of the body and the rest of the parts are going to be made as you go because they depend on the thickness of your cardboard and how many layers of duct tape you use. Because I used thick pizza box I only needed one layer.
这些是机身的主要部分，而其他部分在之后继续制作的时候再制作，它们取决于你使用的卡纸厚度及使用了多少层胶带纸。我用的是比萨盒子，所以我只需一层胶带纸。

Step 3: Reinforce you parts

步骤3：加固零件

Now that you have all you parts cut out you have to reinforce them. First cover one side of a piece with duct tape and the cut the extra tape, the cover the other side and cut the extra tape.
Repeat this for all the parts, if your cardboard is not strong enough repeat this step putting more layers of tape until you are satisfied with your result.
剪下所有零件后，就开始加固它们吧。首先将一面用胶带纸覆盖，剪去多余的胶带纸，接着把另一面也盖上并剪去多余的胶带纸。所有零件都如法炮制。如果你的卡纸不够坚韧，那就重复这步骤，盖多几层胶带纸，直到你对结果满意为止。

Step 4: Start building

步骤4：开始组装

Now the best part, when you see that your robot starts taking shape.
进入最精彩的部分，你能看到机械臂开始成形。

The next piece you have to make is a cube that is going to hold together the bottom of the 2 “A” pieces
下一步要做的是，做一个立方块，用来把2片A的底部集在一块。

For my robot I used a cube that is 3 inches wide by 1 inch sides (cube= 4 sides)
以我的机械臂为例，我用的立方块是3英寸宽乘以1英寸高。（这里的立方块只有4个边）

After you cut and fold the cube reinforce it with tape.
在裁剪下来，折成方块后，用胶带纸加固之。

Step 5: Continue building

步骤5：继续组装

The reinforce cube needs to be attached to the bottom of the “A” piece (the bottom is the longer part 3”)
加固用方块需要安装到A片的底部。（底部是指3英寸长边）

First attach it to one piece and then the other.
Put your piece in the floor to make sure the cube is level before taping.
首先，将一片先安装起来再安装另一片。把片片放在地板上安装，确保在用胶带捆绑前方块是水平的。

The technique i use for taping i call it L taping, look at the picture so you can understand better.
我将我捆扎的技巧称为L字捆扎法，看图你就能很好理解了。

Next attach the "A+CUBE+A" piece to the 6" circle base using L taping (use as much tape as you think is necessary to get a strong hold )
下一步就是将“A+方块+A”结构和直径6英寸的圆形地做以L字捆扎法捆在一块。（只要你觉得需要，尽量用多点胶带纸来强化结构。）

Step 6: Make your next cube and holder for the first syringe

步骤6：为第一个注射器做方块和固定座

Hold your two “B” pieces on the inside of the “A+CUBE+A” piece and measure the space between them, that is how wide your cube needs to be.
Now make your cube with your new size following step 4
( in my case my new cube is 2 1/2" wide)
keep the 1 inch measure for the sides of the cube.
在“A+方块+A”结构内固定两块B片，并量出它们之间的空间大小，作为你要做的方块的尺寸大小。接着按照步骤4所说那样做一个新尺寸大小的方块。（以我的为例，尺寸是2.5英寸宽）保留1英寸空间，预留给方块的厚度。

After making your cube attach it to the “B” piece leaving 1 inch space from the end.
在做好方块后，将它和B片固定在一起，在末端保留1英寸空间。

Next depending on the thickness of your cardboard make 2 or more squares as wide as your first cube (in my case 3 inches) by 1 inch long and tape them together , this will be taped to the middle of the “A+CUBE+A” piece to hold the syringe.
接着就取决于你使用的卡纸厚度了，做多2块或更多像第一个方块大小（我的话就是3英寸）的正方形，长度是1英寸。将它们捆在一起，再和“A+方块+A”结构中央固定在一起，用来固定注射器。

Place the square vertical and give it just a little of an angle.
将正方形垂直放置，并稍微将它倾斜一个角度。

Step 7: Build next part and next cube

步骤7：制作下一部分和方块

Repeat the beginning of step 6 but with the "C" pieces. Hold you “C” pieces on the inside of the of the “B+CUBE+B” piece and measure the space between them, that is how wide your cube needs to be (in my case 2 inches wide) by 1 inch long for the sides.
重复步骤6的做法加工C片。将C片和“B+方块+B”结构内部固定在一起，量出它们之间的空隙，作为又一个方块的宽度大小（我的话就是2英寸宽），而每边长度1英寸。
Reinforce the cube and the attach it to the corner of the "C" pieces.
加固方块，将它和C片的边角固定在一起。

Step 8: Make the holder for the claw and the claw

步骤8：为机械爪做固定座，及制作机械爪

Now you have to make the holder for the claw that goes between the “C+CUBE+C” piece.
The holder is a “rectangular cube” that is 4 inches long and the sides are 2 inches by ½ inch.
现在你需要去做机械爪固定座，它位于“C+方块+C”结构中间。固定座是个长方体，长4英寸，底边是2英寸乘以0.5英寸。

follow the same steps in step 4 and the attach to the front of the "C+CUBE+C" piece flush with the front.
遵照步骤4那样，将其与“C+方块+C”结构平齐地固定在一块。

Now make the claw, the "D" piece. depending on the thickness of your cardboard you need to put as many layers of cardboard and tape as you want until you get a strong claw (in my case 2 layers of cardboard and one of tape)
然后做机械爪，就是D片。由你使用的卡纸厚度所制约，你需要用多层胶带纸进行加固，直到有一个坚固的爪子形成。（我的话，就用了两层卡纸和一层胶带纸）

Make hole in both parts of the claw large enough for your 1 1/4" screw
在两块零件上钻洞，给1.25英寸螺丝钉通过。

Now make a hole in the front corner of the claw holder in the "C+CUBE+C" piece
接着在机械爪固定座前角落处，“C+方块+C”结构那里也钻个洞。

Put you screws and attach the claw parts.
用螺丝固定机械爪零件。

At this point you should be half way there, hold the parts on their place and drill you have to drill in the joints of the robot across the inside of the cubes and place you screws.
你应该完成了一半了。固定零件在它们的位置上，钻机械臂在方块内连接节点所需要的孔，并上好螺丝。

Step 9: Attach to base and make hydraulic system 1st syringe

步骤9：安上底盘，用第一管注射器做液压系统

Now attach the robot to the base.
现在将机械臂安装到底盘上。

Drill in the middle of the cube at the bottom of the "A+CUBE+A" piece and on the wood for the base and put your 3" screw.
在“A+方块+A”结构底部，方块的中央钻个洞，在木板上也是，用来给3英寸螺丝通过。

Now to start with the Hydraulic system.
然后开始做液压系统。

Attach you first syringe to you holder on the "A+CUBE+A" piece (just like the picture)
将第一管注射器和固定座固定到“A+方块+A”结构上。（如图所示）

Now cut two pieces as wide as your second cube by 1/2 inch tape them together and attach this to the 1 inch space you left in the "B+CUBE+B" piece (just like the picture)
接着切下两个像第二个方块的宽度乘以0.5英寸长度大小的方块，将它们捆在一块，将这安装到“B+方块+B”结构中预留的1英寸空间。（如图所示）

then put a pin in that new piece and tape around it then tight a piece of rope to the pin and from there to the syringe tight and cut, make sure the arm is down and the syringe is all the way out to get the right length of your rope (refer to picture for better understanding)
然后在新的结构上放置一枚图钉，用胶带捆一圈，并绑上绳子在图钉上，长度为注射器量程，然后剪掉多余绳子。这样就能保证机械臂弯曲时，注射器能运动的长度就是绳子的长度。（看图比较好理解）

Step 10: Second syringe

步骤10：第二管注射器

For the second syringe you need to make a holder in the top part of the "C+CUBE+C" piece.
在对第二管注射器加工时，你要在“C+方块+C”结构顶部做一个固定座。

Use the same procedure as step 9, make sure the arm is down and the syringe out to get the right length for the rope.
和步骤9的处理流程一样，确保机械臂弯曲时，注射器的量程就是绳子的正确长度。

This is completely adjustable depending on how high or how low you want your arm to move, play around with the length of the rope to find out what works best for your robot
这完全是可调的，取决于你希望机械臂能抬多高或多低。调整绳索长度，找到你的机械臂最理想的工作状况。

Step 11: Syringe for the claw

步骤11：操作机械爪的注射器

The syringe for the claw is going to be directly attached to the claw with duct tape, make sure the duct tape is not too tight so the claw can move freely.
机械爪用的注射器直接用胶带纸固定在机械爪上就行，只要别太紧，让机械爪能灵活运动就好。

Step 12: Syringe to turn the arm

步骤12：用注射器转动机械臂

At the base of the robot attach a pin and the a syringe about 3 inches from the pin
在机械臂底盘上安一枚图钉，在离图钉3英寸远处放上一管注射器。

Attach a wire from the pin to the syringe when the syringe moves makes the arm rotate left or right.
将图钉和注射器之间用线连接，这样只要注射器有动作，机械臂就会左右转动。

Now tape to the wood base 3 syringes next to each other, each of these are to be connected to the syringes in the arm.
接着将3管注射器并排粘到木头底盘上，每一管都用软管连到机械臂上的注射器。

Step 13: Run the tubing to all syringes

步骤13：用软管操作所有注射器

Run the tubing to all the syringes and the fill with water and enjoy.
在软管内装满水，按下注射器和软管，享受成果吧。
