Engineering Concepts

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

Above are the requirements for the prototype.

At the end of our project we are going to build a sumo battle bot.

Above are the requirements for the sumo battle bot.

Moving Servo

With the help of a reference we coded our first servo to move.

Servo wiring

We used TinkerCad to show a representation of our servo wiring.

Two Independent Servos

Today we learned how to wire and code two independent servos.

Research

I like the top protective layer.

I like how the wires are ordered.

I like the red color.

Battery Power Wiring

Today we learned how to wire the battery pack through TinkerCAD.

Battery Power

We used what we learned on TinkerCAD to wire battery packs to the breadboard to make our wheels independent from the computer.

Robot Base Built

We built a robot base capable of supporting our robot's movement.

For-Back-Left-Right

Today we coded our robots to move in the 4 fundamental directions.

Function Code

Today we learned how to shorten our code using functions.

Mini Track

Today we coded our robots to traverse a mini track.

Learning Technical Sketching

Draw horizontal line
Draw vanishing point
Draw fronts of forms
Draw diagonals to the vanishing point
Draw the backs of forms
Erase construction lines
Shade forms

OnShape and Physical wheels

We designed our wheels with precise measurements on OnShape, then laser cut them and attached them to our hobby motors.

IMG-1681.MOV

Hobby motor moving.

We coded our first hobby motor to move.

IMG-1682.MOV

Two hobby motors moving

We coded a second hobby motor to move.

IMG_1800.MOV

Ultrasonic sensor working

We coded an ultrasonic sensor that shows its distance from objects on a serial monitor.

IMG_1807.MOV

Robot avoids walls

We coded our robot and ultrasonic sensor to sense the distance from objects to avoid them.

IMG_1627.mov

Bluetooth connected

We connected a Bluetooth board to input commands from our phones to control our servo robot. We used a LED to show the connection to the phone.

IMG_2146.MOV

Robot base built(2)

We built a robot base capable of supporting our new robot's movement.

Final Robot

Robot Idea Development

My plan for making my robot is to design Perry the platypus. I plan on making the body more of a box shape. I will cut holes in the bottom of the design for the wheels to fit. I also plan on making Perry's signature hat and allow it to be removeable.

Kitty Condo or Dog Kennel Calendar

We are tasked with creating a kitty condo or dog house. We have six weeks to do this and a more detailed calendar above.

Project Constraints and Stamps

The constraints for this project are listed above.

Shared Research Slides

Research

We researched modern homes and dog kennels to use as ideas.

4 Sketches

We brainstormed four sketch ideas for our dog house.

Scaling Practice

Today in class we practiced drawing a dog house and scaling dimensions.

Detailed sketch

We were tasked with creating a detailed drawing we would use to plan our builds.

Onshape 1

We created our pieces in Onshape to create a cut-list for the laser cutter.

Prototype 1

We laser cut our pieces and created our first prototype/rough draft.

Onshape 2

We refined our desgin and made sure the pieces fit together for our final prototype.

Prototype 2

We laser cut our pieces from our final Onshape design and put them together.

Imaging practice 1

We created images on our Adafruit Feather using Mu. I chose to create a thundercloud.

Google Colaboratory

Final Machine Learning Model

Our goal was to create a model that could recognize each student with pictures. The data in this model was created by hundreds of pictures of each student. The model turns the pictures into matrices and creates patterns used to differentiate each student. My model was able to do this with 95% accuracy.
