Pictures of the final prototype

Work in progress: the final prototype

We lasered for the third time. This time we are happy with the results.

We connect the several plates together with the snap connections. We do this for the two halves.

We place the wheels in the part with the holes.

We attach the battery to the aluminum frame.

Then we put the second half on top of the first one.

These two will be fixed together with straps.

PROTOTYPE #27

We cut a little more of the tube, because it wasn't enough.

CONCLUSION:

Expected positive feedback: The ball launches in a nice curve.

Unexpected positive feedback: /

Expected negative feedback: /

Unexpected negative feedback: /

Makeabilityscore : 4

PROTOTYPE #26

We change the position of the tube, and we though that the ball lost power because the ball hits inside of the tube, so we took a piece of the ramp away so it wouldn't be in the tube as long.

CONCLUSION:

Expected positive feedback: The ball is launched in a nice curve

Unexpected positive feedback: /

Expected negative feedback: The impulse is not enough because the battery was getting low

Unexpected negative feedback: /

Makeabilityscore : 4

PROTOTYPE #25

We thought maybe we could use some tube as a ramp.

CONCLUSION:

Expected positive feedback: The ball shoots out in a high curve.

Unexpected positive feedback: /

Expected negative feedback: /

Unexpected negative feedback: The tube doesn't fit and shoots out with the power of the ball.

Makeabilityscore : 4

PROTOTYPE #24

The important point in this prototype is the ball's exit. First, we don't use any aid.

CONCLUSION:

Expected positive feedback: The ball launches

Unexpected positive feedback: /

Expected negative feedback: /

Unexpected negative feedback: The ball shoots out towards the ground and doesn't fly far
