DIY Cardboard Dancing Robot
Intro: DIY Cardboard Dancing Robot
Hey guys, I'm Angelo, a form 4 student studying at HK, today I'm gonna show you to make a cardboard dancing robot based on some parts on the OTTO robot and its arduino program. So what are you waiting for? Let's start building!
STEP 1: Here's What You Need
1- arduino nano board x1
2- arduino shield board x1
3- cardboard box x1
4- servo x4
5- servo arm x4
6- otto leg x2
7- otto torso x1
8- otto foot L x1
9- otto foot R x1
10- a bunch of screws
STEP 2: The Foot
Well a dancing robot has gotta have feet, but it ain't gonna grow by themselves. So i used the feet from the otto 3d file. I attached the foot file from the robot here. And here's what you're gonna do after you 3d print the parts:
1- grab a foot and put the servo in with the gears facing the hole like the second picture
2- then put a servo arm into the slot and connect to the servo
3- use your screwdriver to screw the parts shut
4- and do the same for the other leg, but remember the direction, the side with the servo arm is the back, and the other side is the front.
STEP 3: Torso
Now its time for the torso, i attached the files you need, and here are the steps:
1- attach a servo into the body via hole in the bottom (see picture 2)
2- add screws on both sides of servos (as seen in picture 3)
3- put a servo arm into the slot of the leg, and connect the leg with the torso
4- add a screw to the servo arm
5-do the same for the other leg
STEP 4: Body Assembly
This step is relatively simple:
1- thread the cable through the slot of the inner leg and through the slot underneath the belly of the otto robot, then snap the leg in place
2- do the same to the other leg
STEP 5: Circuits
This build has four servos, so its easy to connect:
1- connect the nano board to the shield board, make sure the plugs face the same direction
2- follow the circuitry on picture 5
STEP 6: Programming
I used mbot to programme the robot with a simple move, the moves are already in the mbot app, but you can still do slight tweaks in the code to change speed and movement range.
STEP 7: To Give "life" to the Robot
Just ready a 9 volt battery and a suitable plug for the jack
STEP 8: The Body
I cut a trapezium from cardboard with a upper length of 7cm, lower length of 10.5cm and height of 10.5cm, and folded it into a trapezoid. After that i folded paper springs with 2cm width paper strips, and decorated the robot with foam balls.
STEP 9: Ready to Go!
Put the body onto the torso and plug the robot, and its ready to go!!!
Have fun while i try to get some sleep!!! Yawn...

I'm trying to learn this stuff (electronics, arduino, robotics etc.) and I think this could make a good educational project for me.
