Project Resume and Budget List

Resume 150:

This semester we are going to make an automatic “roster robot” this robot functions without any kind of control, the principal objective of this robot is fight with other roster robots and pop the balloons of the enemy.

The robot has different sensors to detect the other cars and to do different movements. One of the principal sensors that is used are the ultrasonic sensors, this sensors detect objects in a short distance, and the car has six of them. The car has 4 infrared sensors on the down part, this sensors detect the black color of the battleground, and the last is the digital camera, this camera will detect the colors of the balloons and objects.

The structure is made with aluminum and polystyrene, because we want light and resistant materials for our project, and the motion is made with two dc motors connected to a H bridge for control.

 Budget List: 

Total Cost: 2885 pesos. 

Components of the Project

Project Resume

Our project for this partial is make an automatic gallito robot, this project is great to improve many areas of the engineering specially “control theory and electronic potency”. This gallito robot will be made and design to compete in robots gallito tournaments; the principal objective of it is pop all the balloons of the other robots to win; the robots and the weapon should not been more than 30 centimeters long, width and height.  

Thinking in terms of society, we think that this project is great to awake the interest of the kids to study; maybe in some future they will study mechatronics or any engineering. This is great idea to encourage the next generation of engineers.

 The gallito robots components are six ultrasonic sensors, one digital camera, two dc motors with encoder, one servo motor, infrared sensor, arduino and a battery. Our robot need to make all the movements without user. 

Wave Power Station.

This is the process of the wave power station.

1. First the reinforced concrete capture chamber set into the excavated rock face
2. Then air is compressed and decompressed by the oscillating water column, this causes air to be forced out and then sucked back throught the turbine.
3. Finaly the wells of turbines rotate in the same direction refardless of the direction of the air flow, this generates the energy 

Project Resume

Our project consist in a semi automatic serigraphy machine.

This project is desingned to print clothes and brasalets, but reducing the normal time that have a normal serigraphy machine. we want to make a lighter, useful and transportable machine that print things faster and in easy mode.

Our machine has 2 systems, the pre-drying process and the up and down mesh buttons.

• The pre drying process was made with a hair dryer conected to a pipeline that has little holes that shoot the hot air in the brasalets or the object you print. This mecanims is controled with a turn and off button. 
• The Up and Down mesh is made with a Big DC Motor and the movements of this, are controled with the Up and Down buttons.

The system dosent has a very difficult mechanism, is very simple but it is very useful and dont have much problems to transport or to print. Me and my team think that the principal objetive is completed.

Budget Cost

Material	Description	Cost:
DC Motor	The Dc motor(Direct Current) is a motor that moves to one side, depending how you connect it. This motors are more difficult to control that the servo or step motors, but it has more torque(straight)	200 used each
Arduino	Arduino is a programmable target that has a microcontroller and other electronic components that makes you easy the control the components (sensors, motors, displays etc) of your projects.	350 each
Transistors	Transistors are an electronic components that function as amplification or as electronic switch.	25 each
Aluminum Profile	This profile of aluminum is very light, and beauty, but has a great coast	250 each meter
Aluminum Tube	This tube, are made to be modificated in the “lathe”, you can create a lot of pieces with this material using a “lathe”	260 each meter
Iron Angle	This material is cheap and heavy, but functions very good to make resistand structures	40 each meter
Servo Motor	This motors are like the Dc motors, but has an extra transition that control all the movements of them, those motors are the most famous used in robotics projects.	200 each
H Bridge	This H bridge is a electronic component that helps you to change the direction of the motors(Dc, servos and step motors).	30 each
Serigraphy mesh	Those mesh are used for printing process of serigraphy	200- 300 depending, each
Wood	The wood we use in the project is for fabricate the serigraphy mesh	50 each meter
Serigraphy paint	This paint is special made for serigraphy paint	120 liter
Endless screw	This screw is long, and at the top, it doesn’t have a “head”, those screws are used to move things to the sides	150 each meter
Step- Motor	This motors are the most exacts in control, you can move it 360 grades. This motors don’t have much torque, but are very useful in projects that needs exact movements.	200 each

Resume Second Partial

In this second stage, we made the structure and some of the electronics components of the project, including the H bridge and the mesh motor movement. Another progress that we have is the chronometer and the joint of the other mechanics parts for the structure.  

One of the principal changes that we made is the fact that we modified the structure design, previously the structure had a very complex design, because we realized that it needed so many motors and so many engine work to do a low-comfortable machine that only allowed one print per time. So, for this reason we made a more simplistic design that allows two prints per time with a more efficient mechanism and more friendly operation.

The progress is good until now, because we only have one process left to do, a process which we name “The pre- drying stage”. Later we will implement the control system which is already designed.
