Program

The program...


The start.
This part makes it so that if it cant see anything then it will spin till it sees something or if it spins around too many times it stops (to stop unlimited spinning).
If it can see something then it will go full speed ahead.
It does this so when it cant see the enemy it will find it quickly and when it can see the enemy it attacks it.



This part controlls the light sensor. If it sees the white line it will reverse and turn till it sees something then it will go full speed ahead. It does this so that it wont leave the ring because if it does i will lose.

The only problem I had was that if it saw something outside the ring it would just charge right out of the ring because the light sensor didnt see the line properly, I fixed this by recalibrated the light sensor.

Programming

Idea's - processes:

- Must wait 5 seconds because that is the rules
{
- - Needs to have light sensor as first priority while light says ok
{
- - - Turn until it see's something
{
- - - - Motors go when something is seen
- - - - go back to turning
}
}
- - - else
{
- - - - Motors reverse
- - - - go back to turning
}
}

Final Design

Last Day before the compitition.



Features Of Final Design:
It has a low centre of gravity because that way it cant be tipped over easily.

It has a ramp at the front. After expirimenting with different designs I found that a ramp at the front was better than a wall because it is effective at causing the opposition to lose traction by lifting them off the ground and it is easier to make than a lift which would also be effective if you were able to get it to work properly.

The Ultrasonic senser allows it to determine the position of other robots so it can attack. It is positioned high so that it can see good and it also has some protection from being hit as opposed to being low where it is vulnerable to attack.

Motors at the back because it gives it a good drive and power as which is better because pushing from the back give room up the front.

Light sensor so it can see the edge of the ring and stop because if it leaves that ring it will lose. This is positioned up front to get instantaneous reaction and stop it leaving the ring.

Rear bumper incase of rear attack and also a defense against flipping.

Testing

I tested my robot and i have encountered a problem, the stabilizers at the back are to big and cause tha wheels to lose traction. I plan to fix this by making the stabilizers smaller thus allowing te wheels to touch te ground. This allows for greater traction.

Design Number 2

After my failed helicopter attemp i desided that it was best to keep it simple so i designed another robot that would hopefully dominate the compitition.

As you can see it has a wedge at the front that will go under the other robots and cause them to loose traction. It also has two wheels either side so it will have more traction and it will turn better than if it had four seperate wheels like a car. This setup is quite good because it can turn on the spot.

AWESOME-O

Helicopter Robot

For my robot I thought I would try to build a helicopter because I though that by flying I would have a slight advantage over the opposition. From the start morgan and elliot told me that it wouldnt work but I remained optimistic. After wasting quite a bit of time doing this I realised that they were probably right and that this wasnt going to work. I think the reason it didint work has something to do with the gravitational pull of the earth and also the earths atmospheric pressure.

First Post

Hello
Here is my first post. At the moment I am just experimenting with ideas on my robot, I will try to put some pictures on soon.
