Its a hexapod robot, its only a few millimeters high and its made almost entirely from paper !

Each of the mechanized insect's legs are fully articulated and it has the capacity to move at speeds of up to 240 steps per minute.
Once built this robot can move sideways much like a crab and the legs have a synchronized walking pattern thanks to the mechanism which I will explain in the instructable.
 Also, this little creature is so small you can store it in a match box or even at the bottom of your pocket and although it is pretty fiddly to make  once you get the hang of making them you can make yourself a swarm of miniature, paper robots!
 Furthermore,because this robot is made only from paper and salvaged electronic components your robot army can cost you virtually nothing !

(If you like this instructable I would be really grateful for your votes in the epilog V contest because I spent days cutting these individual pieces with scissors and I would really love to use a laser cutter  to make some more projects like this one and ones with more exciting materials such as plastics. Also with less time cutting I can start to focus on the electronics side of things and design some mini robots which can do things such as pick up objects and perform more complex tasks)

WARNING:
this project is very reliant on the correct dimensions and precisely cut components because it is so small and if there is even a slight error in the measurements the robot is liable to jam and stop working. I have reduced this problem for you by providing a template for the pieces however, take care when cutting. Also I used a pair of regularly shaped gears which I found ,when I tried to test, to be susceptible to jamming and so I will also detail how to make this robot using a worm drive which, according to my walking experiments, will mean far smoother mechanized walking.

Materials:
-paper clip
-4 sheets of A4 paper/ 2 sheets of A4 card
-small motor (can be taken from old RC helicopters or bought from here :http://www.active-robots.com/motors-wheels/small-geared-motors)
-Use two LR44 button batteries if you want your robot to be self contained. If you want to hold a 9V battery while the robot runs along the ground this gives a much faster speed but doesn't look so great.
-small worm gear to fit the diameter of your small motor and an 8mm diameter gear with 18 teeth
-40 small pins
- superglue
-mini switch

what size do I need to print the template onto? should it be A4 size, or half of an A4 sheet?

please add a video
I might design my own after trying out the design displayed here. It will help me understand how the process works.

How does it move? Can you demonstrate if it moves at all with a video?
ledXcrafter10 months ago
Where is da video? Would be great to see it move around!

I built one of these and I think I screwed up the axle. When I turn the axle the plates move back and forth until they tear away from the base. Any advice on making the axle? I made sure all pieces were cut accurately and all holes in the right spot.
I believe this is the case, although the raised sections were only slightly higher that the diagram, I think it was enough to impede the turning of the axle.
I'm just not sure how to bend the paper clip to the exact proportions.

This is so cool. One of the best instructables I have ever seen, and it gives me some great ideas.

Do you have any other similar creations (paper robots) that you could share?

The template is not very precise... I ended up making my own based on your template...

Your template would have worked, it was just that the curves on the center plates weren't uniform and the holes didn't look like they were in exactly the same spot. It looks like you drew it on the computer, so I understand why they weren't perfect.

Great job! I am in the process of building this. I would love to see a video and an example pic of the worm drive.

Great design, just wondering does this robot walk sideways or forward? because by the look of the steps I get an image of the robot walking sideways XD but anyways its a good and simple design!

I do not have much to do this sunday night so i got some parts out of my office and build it. it is a very amazing structure. Great job!

Very cool! Looks like you had a lot of fun doing this project. Thin sheets of Styrene would make it stronger and more durable. You can buy them at hobby shops and craft supply shops. But I love that you made this mini-robot out of paper. I'm impressed!

Amazing!! It will be awesome if you insert a video of this creature in action.

Thanks! Videos are a powerful tool when you want to promote a robot :-)

this looks great, i'm going to stick the template onto some plasticard (sheet polystyrene) to make some sturdier little ones, could also let me downsize your design even more if i can find a small enough motor...

Thanks for sharing

I have an old broken rc helicopter and had been wondering what I could do with it. I'll have to build a couple of these! Great instructable!

I was hoping to see a video of it in action.

Very cool idea though and nice construction!

Can we see it in action Please?
