tenth week

We are in the last week before Christmas and we are a bit revolutionized and wanting to finish much of the challenge because when we return we only have 8 days to finish the challenge. The great advantage of this new challenge is that we do not have an individual exam, but the disadvantage is that we have more things to work in different sections, such as the model, the screen, the robot etc. We have made a breakthrough with part of the challenge because we are working more organized with the passage of each new challenge. We have not yet started the robot since it is missing a battery that has to arrive. The most difficult part of this project is the wiring of the model because we had to remove everything and reassemble it. We have started to do the programming after that we can finish the screen since the PLCs are communicated with the screen. The organization is the most important, for this, we use the gantt where we have what we have to do and thanks to this, we are guiding and controlling the days. This week we will finish the English presentations that are being very fun and entertaining.

Nineth week

          We just finished with the third challenge and now we start the new one, but before this we make the presentation of each group and each challenge so while we make the works we learn a bit more. This consist on making a connection between PLC´s. They are two differents model so thats why we need two PLC´s. On one hand, we´ve to say that we are having some difficulties like there is no motor of the tape and the arm has a sucker, but this doesn´t work because the team before had broken. On the other hand, we going to explain you the functioning of the two models.

          In the firts model, We´ve to programm a cylinder that push a piece and when this happens the arm has to go to take the piece with the sucker that doesn´t work. After this, the arm has to carry out the piece from the cylinder to the tape, but the tape is on the second PLC so now we pass to the other model. Ones the process of the first model has finished the programation makes a comunication to the second PLC. This one, has to pass from a color detector and if it is pink, black or silver each one has their own ramp. While the pieces are passing we have a detector whick counts how many pieces are in the ramps and all this has to be count by a counter on the programm.

          All we are explainig now it has to be reflect on a screen. This screen is a Siemens KTP700 Basic. Here in the right you can see what type of screen we are talking about. Well, this is all from this past week, see you next week with more information and thanks like always for being here with us learning and reading new things.
