The Ada hand struggles to grip objects.
To find a way to make the fingers great at gripping objects, while maintaining an integrated and aesthetically pleasing design.
1. The solution must enable the Ada hand to grip objects without them dropping or slipping.
- See problem section
- The Ada hand is a lightweight and affordable robotic hand, these are key characteristics that a solution musn't impact
- To enable quick and easy manufacture and easy editing.
- Fingertips get the most wear and should therefore be replacable without replacing the whole hand.
- Since the original Ada hand is released under the this license, any derivatives must be distributed under the same license.
Design a set of mouldable Silicone fingertips. There are fingertip grips available which give the hand an excellent grip, however these are ugly to look at and come off the fingers easily. Due to their super soft gel-like surface they collect dirt easily. Mouldable fingertips could be custom designed to fit onto the end of the fingers and to be the right shore hardness and shape to grip effectively. All of the fingertips could be exactly the same, making it easy to order them in large bulk for manufacture and making them easily replaceable if they wear out. Users could use the colour of the silicone fingertips as a further design choice.
1. The fingertips should be a standard shape and size for all fingers.
2. They should connect easily to the fingers with no nuts, bolts or adhesives.
3. They should not slip off easily.
4. They should be very grippy and spongy, capable of gripping a vast variety of objects.
5. They should be easy to clean.
1. Use a home silicone moulding kit to prototype solutions.
2. Use a 3D printer to make the moulds.
3. Rapidly prototype moulds with sugru.
