Prototype 41

EXPLANATION //

Improving prototype 35.
We bought stronger magnets and attached several magnets on the leash.
They are fixed on a wooden piece and stick out.
The other part, attached to the wooden arm on the wheelchair, contains a magnet too.
But this one is fixed at a distance in a whole in the wood.
In this way it is more difficult to perform shear force on the magnet connection.

visit hachiko 17/04

testing of prototype 33:
using the box we designed, in combination with a little rubber ball or a golf-ball in stead of the tennis ball (clicker training)

1. we see a problem: when the dog approaches the box from the wrong direction, the ball isn't fixed well.
2. problem: the red rope turns and twists around the leash: the dog can't detach himself anymore
3. jump up to attach his collar+leash 
4.insert the head of the dog in the loop: the rope stays open well!
