22-23 Engineering Concepts

Robot Project

Today we learned that we are that we are starting this semester with a robot project.

Above are the requirements for the prototype.

At the end of our projects this is what we will need to do.

Above are the requirements of the final sumo bot.

Moving Servo

Today we used a reference to wire and code our first servo to rotate back and forward.

Servo Wiring

Today we learned how to create a visual representation of our circuit using TinkerCAD.

Research

I like how the motherboard isn't showing.

I like the design of the car.

I like the cable management.

Two Independent Servos

When my robot turns left or right one of the wheels move whiles the other stays still.

Battery Power Wiring

In TinkerCAD we made an accurate representation of the wiring of our Batteries.

Battery Power

I used the TinkerCad as a guide to wire my actual Batteries.

Mini Track

I used functions to code my Robot to follow a mini track.

Robot Base Built

I built a base for all my electronics to work.

Function Code

I coded a function to make my code a lot simpler.

#include <Servo.h>

Servo Left; // create servo object to control a servo

Servo Right; // create servo object to control a servo

// twelve servo objects can be created on most boards

int pos = 0; // variable to store the servo position

void setup() {

Left.attach(9); // attaches the servo on pin 9 to the servo object

Right.attach(11); // attaches the servo on pin 9 to the servo object

}

void Forward(){

Left.write(180);

Right.write(0);

}

void Backwards(){

Left.write(0);

Right.write(180);

}

void TurnLeft(){

Left.write(0);

Right.write(0);

}

void TurnRight(){

Left.write(180);

Right.write(180);

}

void Stop(){

Left.write(90);

Right.write(90);

}

void loop(){

Forward();

// tell servo to go to position in variable 'pos'

delay(4500); // waits 15ms for the servo to reach the position

TurnRight();

delay(1185);

Forward();

// tell servo to go to position in variable 'pos'

delay(7000);

TurnLeft();

// tell servo to go to position in variable 'pos'

delay(650);

Forward();

// tell servo to go to position in variable 'pos'

delay(5000);

Backwards();

delay(5000);

}

Forward Back Left Right

I made my robot move in every direction.

Two Independent Servos

My servos moved at different times.

Drawing

I drew shapes in single point perspective.

Avoid Walls

I made my robot avoid walls using a sensor. The sensor tells how far a wall is by playing a sound that we can't hear and waiting for it to return. The code uses "if" and basically says "if distance less then ten move backwards and turn left"

Blue Tooth

I connected my robot to my phone using a Bluetooth board. My phone sends a signal that my board connects to. With using an app called "dabble" I can control my robot.

Sketch

This is the Sketch that I made for my design. My plan is to make a fully functioning Mystery Machine. I want it to be painted the same colours too.

My Robot(The Mystery Machine)

Moving Robot

It works

Crowd Pleaser: Everyone loves Scooby Doo. Who could root against The Mystery Machine.

Wow Factor: It is very fast for something it's size. The crowd will be suprised after this amazing giant car flies around the Arena.

Colors: The colors on my robot are the same as in the Mystery Machine. Green and Blue!

Element and Principles of Design: Unity, Color, Shape. The Colors are obvious on this Car! Unity: The car blends together so well! Shapes: You can see all the shapes on this, from the flowers to the patterns on the sides.

Advanced: Cad: All of my Sides were built in Onshape. So were the wheels.
