For the 5th year birthday of my grandson Benjamin, I decided to make an articulated green robot out of scrap.
First step is to gather a lot of plastic caps, bottles, and small plastic parts.
I was inspired by some pinterest pins, but I didn't tried to reproduce them. It is like a collage, you have to be open to what the parts in front of you propose... The starting point was a big plastic surprise egg from Eastern. At the end it is green robot proudly standing on its legs.
Benjamin adopted it!
I also published this instructable in french on my blog, you can visit it, you will find some more ideas.
Step 1: The Legs
To make the legs, I used :
- hemispherical parts to make the attachment to the body
- golf balls to make the knee hinges
- rubber dampers from a turntable record player
- green aluminium tubes cut in pieces (I don't remember from where)
A rubber band is going through all the parts and is secured with a plastic bead. The first rubber band I used was too weak, and I had to reassemble everything with a rubber band which is used in clothes.
To tension it enough, I attached the rubber bands from each leg together.
Step 2: The Head
The head is made of plastic caps, a cable connector, attached together with a screw going through all the parts, and a nut in the body.
Step 3: The Arms
For the arms I used again the hemisherical parts to a make the shoulder attachment
The arm itself is a piece of an alumium beer bottle, you will recognize the brand.
Then a plastic cap and finally a small part to make the hand.
I did the same than for the legs: I attached the two rubber bands from right and left arm together.
Step 4: Secure the Upper and Lower Parts of the Body
It is very easy to assemble the robot with body (the egg) being in 2 parts.
The drawback is that is not so firmly attached together.
To secure it I made the rubber band from the arms going through the bottom (there is a slot) and attached two beads together.
At the end this robot is male and female, what do you think?
Step 5: It's Done, Enjoy Making Some Gym...
With the rubber bands and the balls, the arms and leg can take various positions.
The 2 parts of the body can turn independently 360°
The head also can turn 360 °.
It is a very flexible robot which can stand on its feet.
