Summary

Summary

The purpose of this integrated project is the designment, construction and control of a mobile robot. In later time, mobile robots were determinated by users; for example, the “rooster of Estrasburgo” was a clock with the shape of a rooster that has the function of being autonomous. Since this robot, there were developed through time more robots with more complex characteristics.

In this case, the robot will be an autonomous implementation because it is composed by sensors, electronic components and a fuzzy logic of control that produced a more efficient movement in a combat situation, all these determinated actions are thought to complete certain conditions which are base on electronic analysis, kind of materials that composed the robot, control theory applied to the function of the mobile robot having as reason the optimal performance so the robot could move inside a determinated surface with other robots that will have the same objective, to burst the enemy balloon and be the winner if its balloons continue inflated at the end.

It is thought that this robot could be used to help disabled people, to serve as an analyst in case of a natural disaster and to give an special vision to the user.

Report

The autonomous movil robot for a game of “gallitos” has its importance in the application of acquired knowledges to design and construct a prototype which be able of identifying and attacking a target in an autonomous way. It is interesting because in its construction there will be use elements and techniques of fuzzy logic, a logic that classify a value/magnitude after a comparison between two measures, which is more effective than clasic logic (true/false, tall/small, large/short, etc).

The implementation of a system to burst balloons is challenging because it is needed a device that could detect the target at certain distance and quickly. Because of that, it has been considered the use of a camera and ultrasonic sensors.

Other problem is the correct calculation of forces, measures of vehicle and conditions in which the prototype will work. In this way, there have been calculated some values as the torque and speed of the vehicle according the specifications of the motors and the measures of the wheels. Chasis of the vehicle is based on the good operation and ubication of the sensors and the rotation of the wheels.

However, it seems that the principal problem is the addition of an effective alimentation system which could supply the energy or the driving force for a correct operation of prototype. Even is thought the used of batteries; there will be considered the used of a complementary energy system or devices.

Wave energy systems

Wave Energy Systems

Ocean waves are created by surface winds. The most powerful and consistend waves are created by strong prevailing winds in high latitudes. 

Wave energy is rapidly emerging as one of the best means of harnessing energy from the ocean.

•  Wave Roller

As the wave roller panel moves and absorbs the energy from ocena waves, 

How can the energy of sea waves be converted in to electrical power?

The hydraulic piston pumps attached to the panel pumps the hydraulic fluids inside a closed hydraulic circuit. The high-pressure fluid are fed into a hydraulic motor that drives and electrici generator. The electrical output from this renewable wave energy power plant is then connected to the electrical drid via a subsea cable.

summary PI

The prototype have an up and down mesh system, two print bases to put the bracer or plain objects, which allows the user to print two objects at the same time. Also, it has a pre-drying system.

All the system is controlled by the Arduino microcontroller which reads the input signals of the buttons with a read loop function, and evaluating the current state of the mesh in every moment. The buttons control the mesh movements and the on/off pre-drying activation, the display with the timer measures the pre-drying time and it only cunt when the mesh is up and the dryer is activate.

Whit finally point the prototype works fine use all the devices and the object was printed by the machin, getting a lot efficiency  because it can print two sheets of 7 bracer per base, which means 14 prints per time. This project help us to learn compromise and the team work.
