CAD Dimensioning arm

I made a parametric CAD assembly of the arm with a rough representation of the head and seat (top view)

and changed the numbers up till they made for a good end result.

Movie of the moving model

First three pictures are the opening of the arm:

Arm + treksysteem + rekkers (keert terug)

Expected:

>Good

Works just fine both ways return verry fast

>Bad

due to dead moments the multiple elastics had to be used.

Unexpected:

>Good

draw weight has increased but not tremendously still verry doable.

>Bad

returns maybe a bit to fast for comfort

Arm + treksysteem (zonder terug te keren) (movie with 31)

 Miniature version of the final product (spuug maquette)
>Arm can extend
>Arm can not return without enabling the release
>Minimal force required

Expected:

>Good

Works just fine one way return system is not jet implemented

>Bad

Unexpected:

>Good

Way less resistance then expected (and will be even further reduced with proper production techniques and materials.

>Bad

gear gets damaged due to prototype material choices.

not car friendly (release broke)

Blokage Systeem

Linear blockage system when you pull r to l there is no resistance but when you pull l to r you can't move.

This is changed when you reach the end of the system then you can return to the original position.

Expected:

>Good

Works just fine one way.

>Bad

not really the needed solution

Unexpected:

>Good

>Bad

knots in the rope made returning impossible and with smaller nots the rope slid through the drop.
