Robotic Hand

I made robotic hand made out of foam with moveable fingers using motors and Arduino. This projects purpose was to show our teachers that we have an understanding on the things we were taught and actually use these key things inot one big project that incorporates math ex. geometry, and coding as well as technologies ex coding, wiring, and electric components.

Rubber bands

Paper clips

Foam

Sanding block

Hot glue

Fishing line

Needle/Pin

Wires

Motors

Arduino

Exacta knife

Pliers

Arduino

step 1 is to create a outline and measurements of one of the group members hand and apply it to the foam and cut out the fingers and palm and forearm. Then use sandy block and shave away the corners and make the finger a cylinder shape only sanding one way the tire time and sand it to have a semi sphere on the top of the finger to symbolize a human finger. Finally use joints on the group members hand and apply that to the fingers and cut them into the sections according to the marks cut into joint sections and create angle so they are able to bend when put together.

step 2 we had to make the code to calculate the volume of the fingers and then the volume of the fingers when cut out and the materials wasted when cut out.

step 3 we had a pin and fishing line and sewed the fishing line through all the fingers and into the palm and forearm and then used cut paper clips shaped into little u shaped pins and use 5 per string and secured the line by sticking the paper clip into the foam along the forearm then on the top of the fingers we hot glued little cut pieces of rubber band so the fingers can open with the elastances after the string pulls the fingers shut.

finally last step we created a code for the Arduino Nano and the motors this code rotated the motors the amount and degrees we needed for the fingers to bend the right amount we hooked them up with wires. the motors were slightly imbedded into the foam so it doesn't move when turned on. This code has void loop and void setup i defined each finger and used that the void setup for each finger port and in the void loop i put the motion or setup name into that and it will rotate the motors the degrees its told to.
