We have decided to go with design number 3

Design 1

Pros:

• It has the ability to acquire the can within the claws because it will be surrounded at all 4 sides by the claws.
• The simple structure allows it to be easily constructed.

Cons:

• The movement of the claws will be slow due to much bending at the “joints”.
• The thickness of the claws may not be enough to acquire the can if it topples

Design 2

Pros:

• It has the ability to acquire the can within the claws.

Cons:

• The car may shift to the side when moving towards the can, so the claws may not be able to open wide enough to catch the can.
• The claws may not be strong enough.

Design 3 (selected concept)

Pros:

• The stationary claw ensures that the can is secured within the claws because the can will be pushed against it and will not fall.
• The movement of the claws will be fast because only one claw needs to move.
• The simple structure allows it to be easily constructed.
• It will be easy to program because only one claw is moving left to open and right to secure the can within.

Cons:

• The car may shift to the side when moving towards the can, so the claws may not be able to open wide enough to catch the can.

Design 4

Pros:

• The claws will be strong enough so the can will not topple.

Cons:

• As the claws need to slide left and right, it may not be as easy to construct.

Design 5

Pros:

• The 3 claws will ensure that the can is caught within them.

Cons:

• The can may drop easily from the claws.
• The height of the claws may not fit within the height limit given.
