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.

Step 1: Materials:
– Pieces of cardboard
– An empty soft drink
– Two servomotors
– A Arduino Uno
– A Joystic Shield
– Arms for the servants
– Three screws
– nuts and a washers
– Hot glue, scissors, knife, etc. …[/box]
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.
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.
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.
