While the Ada hand is capable of gripping a pen, it can't grip the pen firmly enough to write easily.
To find a way to enable the Ada hand to firmly grasp pens of varying sizes so that it can be used to write.
1. The solution must not impact on the normal operation of the hand
- It must help with grasping pens but not prevent it grasping other objects
- As a minor improvement, the solution shouldn't change the manufacturing processes
- Since the original Ada hand is released under the this license, any derivatives must be distributed under the same license.
To design a "notch" or "hole" inbetween the thumb and index finger which a pen could be fed through or could rest on and/or be pinched by. This could provide enough stability to maintain a good grip on the back of the pen while the pinch grip held the pen nearer the tip.
1. Design a small "Notch" feature to secure a pen between the thumb and index finger
2. It should be 3D printable
3. It shouldn't get in the way of any finger movement or grip patterns
4. It should guide the pen to the pinch point of the thumb and index finger where it would be held
5. It should be capable of holding pens of varying diameters, from handwriting pens to whiteboard markers
1. Leverage the flexible property of the Ninjaflex to create a pinching effect on the pen shaft.
2. Prototype by printing a partial hand (just finger and thumb) to save time.
3. Work from the Ada design files in Blender.
