Visit 4 to Jana

The previous attachment system did work but the result was too wide. Jana couldn't ride trough the door. So we tought about another solution. We came to a system where the machine is suspended from the armrest.
We do this by attatchin a alluminium loop on top of the machine and because a part of the machine is under the armrest we gain a few centimeters.

In the final prototype we'd like to attatch a screw at the top so Jana can fixate the machine.

To detach the machine Jana first has to loosen the screw and then by lowering her wheelchair on the same system that was used in the previous test.

We also tested if she was able to drive through a door.

We also tested the latest version of the machine itself. Jana aswell as her dog were happy with the result.

We tested the attachment system with a rough prototype that presents the size. The system defenitly works, we will only need to attach the final device on the right height to go under and over it with the wheelchair. 

The bolts in the prototype are not the right size yet, that's why the prototype is hanging so loose, hat problem will be solved in the final product.

-          We tested the prototype with the wheel-system at Jana’s place. Jana was happy to see our prototype, especially the DIY-solutions (PVC, wood rests…) were seen as a strong point of the product. The shooter still only shoots for 10 metres, she said it would be cool if it shoots further, but like it is now, it shoots already further, higher and in the right direction then when she throws the ball with her throwing stick.

Because her new wheelchair won’t arrive for 2-3 months, we couldn’t really measure or test the perfect spot to attach the tennis ball shooter. In the following posts, you can read some aspects we learned during our visit.

Feedback from Jana

Contact with Jana learned us:

• Good System
• Don't use the battery of the wheelchair
• Enough power left to drive? 
• Garanty of the wheelchair falls away
• Can the ball go further? In the following movie it goes further with the same system:
