Integrated Project Report

The gallito robot is a project that pretend have a big impact in our mecatronics knowledge, we think that also we can have an impact in the MDG's (millenium development goals. Whit the idea to use in the class, whith the unmanned prototype we can save a lot of lifes. We only need to implement the mecanism to differents ideas in things like hospitals, army, firefighters, etc. So our Project is an robot gallito, we  based our Project in the idea to build a war tank, basically we use the Caterpillar to move the Project and Steel plate to all the body of the prototype. To the control we use 2 diferents types of sensors (the ultrasonic and the infrared sensor). To detect the enemies and to detect when the robot is going out of the area that is allowed into the game to dont lose for a violation of the rules.

Wave energy systems

WAVEROLLER

How it works?

Is a plate anchored on the sea bottom by its lower part. The back and forth movement of surge moves the plate, The kinetic energy transfer to this plate is collected by a piston pump.

Waveroller is a device that converts ocean waves to energy and electricity.

First the panel moves and absorbs the energy from ocean waves the hydraulic piston pumps that are attached to the panel pump the hydraulic fluids inside a closed hydraulic circuit.

Then, the high-pressure fluids are fed into a hydraulic motor that drives a generator.

Finally the electrical energy is transported to the energy powerplant.

Resume

On this third parcial our team finish our semi-automatic serigraph machine in a timely manner,
our project have two valves and two pistons, this valves controls the movement of the pistons, and have a dc motor that with a help a inductive sensor stops in the differents processes like a pre drying that consists in a nozzle and a fan, when the inductive sensor detect the fan activate and dry the t shirt. Finally our proyect worked in excellents terms.

The most difficult processes in the proyect was the mechanic part because this part was the most time-consuming but thanks to the enthusiasm of colleagues all the the problems were completed in a timely manner having time to do more test of the prototype, obtaining a final successful test, ready to show it to the public.

Progress

The progress since the third week of February until the second week of April. The team focused on the development of the mechanism of his silkscreen automation system distributing the jobs  between each of the members of the team.

We building the structure of the base of prototype, and assemble the motor with the chain, other members designed, elaborated and welded the components in the pcb.

After did the pcb we connect all devices in the board and test the correct operation, the first test there a were few errors and we proceeded to repair.

The we test again the pcb obtaining a positive result. All test were recorded to have evidence.

 When test the motor we saw that the speed was to fast for the prototype because use 12 volts, we decide use 5 volts in the motor to rotate the base and saw that was better.

The prototype have a 85% of progress, we finish in the third week of may.

In conclusion the progress of project was a good result for the work of all  team members.

Appearence

Chichen Itzá

This building is on the Yucatan peninsula in México, looks like a castle, its triangular at the base, but a the top is shaped like a cubic. In the end of the stairs is shaped like a snake head, and looks like a wedding cake.

GLOSSARY

SILKSCREEN	Screen printing is a printing system in a given object. Where paint is used.
FRAME	The frame is a piece of wood or metal used to strain or stretch the mesh, using staples to tighten it around the frame.
MESH	The mesh is very fine and resistant synthetic fabric stretched and attached to the frame allows passage silkscreen painting.
EMULSION	The emulsion obtained is a liquid of two chemicals, sericrom and dichromate, which are used for printing on fabric.
Squeegee	The squeegee is a tool used to expand the ink on the screen for printing.
silkscreen inks	It is a special ink for printing on the net. Depending on the type of material do you want to print, depend on the use of appropriate ink.
Octopus silkscreen	Is a rotating mechanical element which can be placed several meshes. Its purpose is to have the largest number of meshes for mass production of the items you want to print out.
Piston	It is a mechanical device whose function is to provide a force to move or perform other device. The force causing the actuator comes from a gas pressure (typically air). Currently there are basically two types of linear and rotary actuators.
DC Motor	It is a machine that converts electrical energy into mechanical, causing a rotary motion, by the action of the magnetic field.
Bearing	It is a mechanical device that reduces friction between a shaft and the parts connected to it through rolling, which serves as support and facilitates displacement.
Pressure regultor.	The pressure regulators are flow control devices designed to maintain a constant pressure. This must be able to maintain pressure, unaffected by changes in process operating conditions for which they work.
Pneumatic solenoid. DS18B20 temperature sensor.	A solenoid valve is an electromechanical valve, designed to control the passage of a fluid conduit or pipe. Temperature sensors are devices which transform temperature changes into changes in electrical signals that are processed by electrical or electronic equipment.
Inductive proximity sensor.	These sensors incorporate an electromagnetic coil which is used to detect the presence of a metallic object driver. This type of sensor ignores non-metallic objects.
Relays.	It is an electromechanical device. Functions as a controlled by an electric circuit in which, by means of a coil and a magnet, a set of one or more contacts for opening or closing other independent circuits switch is actuated.
Protoboard.	The protoboard is a tool used for testing circuits and knowing if they work.
Resistances.	It’s a device that cause an opposition to the electrons that flow in a circuit.
Gear.	The gear is used in a mechanism for transmitting the power from one component to another. The form of a gear like a toothed wheel.
Transistor.	It’s a little semiconductor device used as an electronic switch that works with an electric pulse.
Arduino.	It’s a free hardware platform, based in a plaque with a microcontroller, designed to facilitate the use of electronic in multidisciplinary proyects.
Screwdriver.	Instrument used to loosen and adjust crews.
Crews.	A piece of cylindrical metal with a spiral around him. Its used to fasten two pieces of something
Bakelite.	It is a tool made of copper in which we can print circuits and use them by removing the useless copper with a ferric acid.
Ferric acid.	It’s a chemical liquid used as a bakelite cleaner that only leaves the marked lines and “Eat” the rest of the copper in the bakelite.
Multimeter.	This device is used to measure electrical properties, like voltage, current and resistance principally.

processes

how do they make potato chips?

first of all the potatoes are poured on a conveyor belt

firstly the potatoes are washed 

secondly the potatoes are peeled amd  washed again

thirdtly the potatoes are rised and poured to cut by big blades

next the potatoes are fried whith hot oil.

after thar the potatoes are dried to added salt

finally the potatoes are packed in plastic bag and transported to sell
