to mark as completed Robotic paper hand
In this project is showed a robotic paper hand with finger moved by flexinol. The following picture show the hand:
Picture 1: Robotic hand
Flexinol is a particular material. In few words, flexinol is a trade name for shape memory alloy actuator wires. When current pass in circuit connected to finger of the hand,
the flexinol is heated and so the finger moved itself.
The following picture show flexinol material.
Picture 2: Flexinol
An electronic control board is connected to the hand. Each finger of the hand via resistor is connected a single transistor (with led). When led is on, current pass in the circuit and relative finger moved itself because the heat warms and contracts flexinol.
Picture 3: Connection
In the following picture is showed a particular of flexinol and fingers of the hand.
Picture 4: Flexinol fingers
This is the final result:
