Hi everybody! BBTeam presents the solidworks parts, assembly and the arduino code, which is going to run the stuff around!:) Enjoy!!

This is the primary component of the Archimedes' drill. The screw design traps water as it rotates and carries it upwards towards the top.

Part 1. Archimede's drill

This part serves a sheath or case for the screw. It traps the water as it is carried upwards to prevent it from spilling out.

Part 2. Case for the drill

This part is designed to hold the DC motor in place as it rotates the screw.

Part 3. Case for a DC Motor

This shows a cross section of the assembly made from the screw and screw casing. When rotating this will ideally be facing upwards at approximately a 30 degree angle.

Assembly (Archimede's Drill)

	#include <Servo.h> // includes the servo library
	Servo servo1; // assigns servo variable
	int buttonpin = 2; // assigns button to pin 2 on the redboard
	int press1; // creates a variable to count button presses
	int potPin = A0; // assigns potentiometer to pin 0
	int motorPin = 9; // assigns DC motor to pin 9
	int potValue = 0; // creates a variable to track potentiometer value
	int motorValue = 0; // creates a variable to track DC motor value
	void setup() {
	Serial.begin(9600);
	servo1.attach(10); // assigns servo motor to pin 10
	pinMode(buttonpin, INPUT); // assigns pushbutton as an input
	digitalWrite(2, HIGH); // sets button state to high when not pressed
	}
	void loop() {
	press1 = digitalRead(buttonpin); // determines if button is being pushed
	if (press1 == LOW){ // if button is pressed tells the servo to rotate to 179 degrees, wait one second return to 10 degrees, then wait another second
	servo1.write(179);
	delay(1000);
	servo1.write(10);
	delay(1000);
	}
	potValue = analogRead(potPin); // reads the position of the potentiometer
	motorValue = map(potValue, 0, 1023, 0, 255); // maps the speed of the DC motor to the position of the potentiometer
	analogWrite(motorPin, motorValue); // assigns the mapped postion of the potentiometer to DC motor as its speed
	Serial.print("potentiometer = " );
	Serial.print(potValue); // prints to potentiometer position to the screen
	Serial.print("\t motor = ");
	Serial.println(motorValue); // prints the DC motor speed to the screen
	delay(2);
	}

Arduino code

The code allows the drill to be controlled. The drill speed is governed by the potentiometer, while the servo motor is controlled by the pushbutton. The code may be edited later to incorporate an LCD screen and possibly try to automate the servo function with a timing code.

For this meeting Brendan, Mike, Iasha, and Eric were all in attendance during the meetings this week. In total we spent about two and a half hours
