Design

• The T shaped stick is used to lock on the wall so that we can pull it back on the springs to push it out.

• The brakes are used to stop the wall from moving to far forward and braking the whole thing.

• The stick is used to turn the t shaped stick to fit in the whole and the string is used to pull back the wall.
• The wall will be made of metal and

Final Idea

We chose the ARMTS for our idea because:

It has the most practical use in the real world as it can be used with small scale tests and used as a miniture testing version.

The wall climbing car had the most disadvantages.

We already have most of the hardware and software needed for the ARMTS making it the most doable.

Hardware and Software

•Armts

Hardware:Springs, Motor, Mindstorm, Sand, Water, Plastic box, string

Software: NXT (program),

•Wall robot (car) 

Hardware: Drop popz (used as suction pads for climbing), Mind storms

Software: NXT (program)

Advantages and Disadvantages

•Armts

Advantage: Helps scientist study tsunamis and defence in smaller scale

Disadvantage: Wastes water with test attempts

•Wall robot (car)

Advantage: Can be used as a toy for financial marketing towards younger audiences.

Disadvantage: It may fall and break because of the power of the gravity, If the battery runs out on the wall the car will be stuck.

Tech fair thoughts

We have 2 ideas:

A Robotic mini Tsunami Simulator (Armts for short)

I think this is a good idea as it has a practical use as it can be used to test scaled down versions of tsunamis and scientists could test different defenses to protect people against them.

A wall driving car:

I think this isn't a good idea as it has no practical use other than being a children's toy.
