3D Printed Robotic Hand
This 3D printed robotic hand can track my hand’s movements and move its fingers in the same manner. It is a very fun and interesting project to tackle.

My third milestone was getting all the flex sensors connected to servos and then building the hand. I put the hand together and then fed the fishing line through the palm and then fingers. I got a finger hooked up to the servo, but it then got fried because it was trying to move in the other direction. I also had difficulties with getting the flex sensors to respond to the servos. To fix the servo problems I changed my 9V battery to a 6V battery and also added a 5V voltage regulator. To fix the sensor problem, I re-soldered the sensor to the wire and also heat shrunk it to keep it from moving.
My second milestone was getting a flex sensor to control a servo’s movement. This works by having the serial monitor read a voltage value from the flex sensor between 100 and 300. This value is then mapped between 0 and 180 to get a degree measure. The digital pin, which is connected to the servo, then instructs the servo to turn to that angle.
