Today we are recording the final video for the testing which we couldn't do before because the batteries were not available. I will then post all the videos we have for the testing.

What is happening today
Today is the final day to autonomously test our robot otherwise that is it for the standard
Tuesday 28/08/2012
Today I am doing research for the new project 90681. I have to use electronic or control technology to create an outcome that can be used in everyday life. I planned to go with something electronic but I would also like something that I can use to interact with a computer. I was thinking of a circuit that would send me an email if for example someone was entering my room(by having the electronic circuit on the door but also connected to my router/computer and that would then sent me the email)
I will have to do research to see if this project would be realistic and useful to me.
Final robot evaluation 90613
At the start of this standard we hadn’t completely designed the brief. We basically knew that we had to design a robot using VEX and we had to make it autonomous. This meant that we could do some research on autonomy and VEX. I personally was quite interisted in the autonomy side of things so I did more of my research on that.
Once we came up with the breif, to autonomously find and pick up a 1Kg weight, we could start on the design of our robots. The programme that we were going to use was Maya. However this programme proved to be an issue because it was far to complicated and it was extremely laggy on the computers that we are using. We decided to use Google scetchup instead because Google scetchup is a much simpler programme to use and it is less laggy. This was good for me because I already knew the basics of how to use it. Once we decided to use scetchup I had to work out how I was going to design my robot so that it could pick up the weight. I looked through the VEX parts and after seeing the part with the slider I decided that I would make a forklift styled robot.
My robot design was quite simple. I designed a good frame with the forklift on the front. I designed the wheels so that they were attatched with chain. This meant that the wheels could have lots of control and I only needed two motors. It wasn’t till later on that I decided the robot might tip over when it tried to pick up the weight. This problem was easily solved by simply putting a counter weight on the back of the robot.
I think the most important key factors are functionality and knowledge and skills. To design my robot I had to use my knowledge and skills and learn knew knowledge and skills. I learnt new knowledge and skills by learning to use the CAM machine. Knowing how to use the CAM machine means that if we need any parts made we can do easily and accurately. I also did research into autonomy and google scetchup to help design the robot. Functionality is important because the main purpose of the robot is to be able to pick up the weight. This was the main basis for my robot design as my design is a simple yet effective way to pick up the weight.

today we were going to do some work on finishing up 3.1 assessment but we were stopped by an school fire alarm (the second one this week) which turned out to be false then we had to wait for ten or so minutes for our reliever to get the key to open the room.
also terry isn't here today so he can't help us with anything. but i have managed to work on some of the posts that i have written and expand on them which i need to do allot

Today Ian and Jared are working on paperwork for their previous standard whcich I don't need to do because I am assessed in another class so I will work on fixing some of the robots's problem, like the range finder or the motors that come loose each time we do a test.

This video shows the VEX claw in action. With my design i wanted to use the claw. this relates back to the brief because the brief states that the robot that we make will have to autonomously pick up a weight.

This video is my way of researching VEX robotics. in this video it shows the VEX claw in action. This relates back to the brief because the brief states that the robot must be able to pick up the weight. one of the ways that i wanted to pick it up was with the claw.
