There are many components required to make a bionic finger. The bionic finger I made required: a flexSensor, a battery pack, a mini-servo, a nano-board, a 3D printed finger, joints for the 3D printed finger, a wooden board, fishermans wire, and a glove
The flexSensor. This, when attached to your finger, records the angles it's bent at (due to the callibration) and sends the measurements to the miniServo.
The battery pack. This allows us to power the finger without it needing to be connected to another power source, such as the computer. This makes the bionic finger easier to move around and carry.
A mini-servo. This moves in correlation with the angles produced from the flexSensor.
A nano board. This is wear all the code is kept, allowing the seperate parts to know what to do.
A 3D printed finger. This the finger we use. It's seperated into 3 seperate parts with slots for the joints.
The joints. The joints are made out of plastic, allowing the finger to bend.
The wooden board. This is used to hold all the parts together.
Fishermans wire. The wire is connected to the mini-servo and threaded through the bionic finger. When the mini-servo turns, it pulls at the wire which lifts up the finger.
The glove The flexSensor is attached to the glove, which you put your hand inside. When you bend your finger, the bionic finger bend too!
