The position of the screws is amended

CONCLUSION:

Expected positif feedback: It went a little bit further.

Unexpected positif feedback: The noise of motor is nice for the dog

Unexpected negatif feedback: /

Makeability score: 2

PROTOTYPE #15

- Visit 2 to Jana- We have added two screw to prevent that the wheels don't expel again.

Aspect 5: Noise

-          The sound of the prototype was good for the dog, when he heard it, he became excited and he knew that a ball was coming, so it’s not too loud.

Aspect 4: Attachments

-          She found it a good idea to work with the T-gutter on the side of the Permobil to attach the shooter. But then, it should be detachable, because the wheelchair may never be bigger on the sides to be able to pass through doors.

-          She would look for someone with a Permobil wheelchair and look where she would put and attach the product.
Our next meeting will normally be with another person with a permobil too. 

Aspect 3: Launching tube

-          Because Jana has difficulties to put her arm high and far backwards, the launching tube may not be that high. It’s a point we should explore around. 

Aspect 2: weight of the prototype

-          Jana is able to carry the prototype, but she won’t be able to pick it up or do big movements with it.
The prototype is now made of wood, so by a different material choice, the product will weigh much less. Now, we also use two motors, by reducing it to one that’s connected with both wheels, we also take a big weight of the product.

Aspect 1: Weight of the battery

The weight of the battery was very good, it’s easy for her to pick it up or disconnect it to reload the battery.
