This mechanical bull was created as a weekend hobby. The creation process was simple and did not last more than two hours. The materials I already had at home. For those who wish to make an equal, will be a good opportunity to recycle materials and learn how to use the joystick shield with Arduino. Hope you enjoy.

I used a can of soda as a model for the doll bull riding. After that, I drew on the cardboard, cut out the template and glued using hot glue.

Step 3: Joining the servomotors

The servo motors are fixed on each other as shown, using a piece of cardboard to position them correctly and hot glue.

Joining small pieces of cardboard with a hole in the center, was made a bracket to hold the mount in servants.

Step 5: Joining the Servants and the mount

I used a bolt, a nut and washer to secure the mount in servants, according to the figure.
Also used a piece to make the linking of movement between the servo arm and mount. This part should be a little slack for not hang with the movements.

Step 6: Fixing on a base

The base was made ​​with a simple cardboard cutout. I made the design of servo arm that controls the base, cut out and pasted it on cardboard with hot glue.
I used a part of the soda can as a handle to hold the puppets up on it.

Oops! My mistake! I thought I had put a figure showing the connections. I connected the joystick shield as follows:

Wires-----------Sensor Shield----------Joystick Shield
black wire------------ G--------------------- (gate)
red wire -------------- V--------------------- (5vots)
gray wire ------------ A0-------------------- (X axis)
orange wire --------- A1-------------------- (Y axis)

As soon as I can, I get a better picture.
This is great! I hope to build something similar for my "Froggy World" amusement park--of course I'll credit you for the concept.
I like the fact that you used cardboard--it's a great material for models and prototypes; and actually holds up fairly well.

Thank you! I love using cardboard because it is easy and inexpensive. Your playground is getting very good too. I'm watching. I am proud to know that you're gonna build a toy with the concept that I created. Then show us.
