Engineering Applications Project Brief (1).pdfProject Brief
Today I got my project brief, which described what our next project is going to be. We are going to create a robotic arm in class!
Research
Design #1
Design #1
This is a cardboard hand that uses pressure instead of actuators. While this difference means it can't be automated, the claw and arm design could be incorporated into my design.
Design #2
Design #2
This is a 3D model of a four fingered hand, I like the design and the points at which the fingers hinge.

Prototype
This is my gripper design, I used ideas from my research and used four fingers for more gripping power. The process took me a few days and required more power than my computer could provide, but I am proud of how it came out.
Gripper code
Gripper code
#include <Servo.h>
Servo Right;
Servo Left;
Servo Up;
Servo Down;
int pos = 0;
void setup() {
Right.attach(2);
Left.attach(6);
Up.attach(11);
Down.attach(9);
}
void loop() {
Right.write(120);
Left.write(140);
Up.write(130);
Down.write(60);
delay(1000);
Right.write(70);
Left.write(180);
Up.write(180);
Down.write(120);
// tell servo to go to position in variable 'pos'
delay(1000);
}

Base
After installing a motor on some wood, I coded it to move from 0 to 180. This should give my arm a wide range of motion.
Base code
Base code
#include <Servo.h>
Servo Base;
int pos = 0;
void setup() {
Base.attach(4);
}
void loop() {
Base.write(180);
delay(5000);
Base.write(0);
// tell servo to go to position in variable 'pos'
delay(1000);
}
