Robotics:

Do Now

• Take out your note books• Sit in your assigned seats• DO NOT TOUCH THE ROBOTICS PARTS ON

DESK PLEASE!Today:• Group Recommendations• Grades• Robot Build

Group Recommendations

• What is it for- You will be working with 1 other person in the next couple of weeks to program and build robots

• Write your name at the top of the piece of paper• Write down three people in the class you would

prefer to work with• Picks are not official- I will do my best to make sure

your partnered with one of the three.Rule- If I hear you talk about who you wrote down, your request will be invalid

6 Week Grade

• Make Up Work needed to be scheduled by tomorrow (Friday)

• 4 Weeks left- What we are going to do– Activities, Projects, and Test(on what you have

learned in the last 20 weeks)

VEX Structure- Chassis Parts

• Allows us to build a frame to hold our robot• Angle and holes allow us to secure in multiple

directions, making the frame stronger

VEX Motion- Wheels

• Three sizes- Small, Medium, Large• We will be using the Medium in this build

VEX Control- VEX Cortex

• Plastic shell with ports on top, a USB port, and a Battery hole on side

• The “brain” that will store and execute the commands we tell the robot to do.

Today, do not plug anything into it (unless I instruct you to)

The Build

In this build, I want you to focus on two things:• Following directions very carefully (a lot of

specific steps that rely on each other)• Keeping the mess to a minimum

How to keep clean:• Grab the parts as you need them• When we clean up, put everything back that you

did not use

Today- Sit with your partner from yesterday in the same seats

• Tech Club• Finish Builds• Take apart other stuff

TECH CLUB- General Interest Meeting this Thursday* All are welcome (tell your friends who don’t have me)

Today

• Grab your notebooks, sit in your assigned seats

Today• Robot Build Review• Robotic Review/ Overview• Programming Basics – Steps Used To Communicate With The Robot

Tech Club- Afterschool Thursday

What is Robotics (and a Robot)?• Robotics involves the

design, construction, and operation of a robot.

• A robot is a machine that performs complicated tasks and is guided by automatic controls.

Humans Robots

Problem1)Create a Plan2) Create a Program

1) Follow The Plan2) Follow The Program

Solution

Our Roles

Jobs of Human vs. Robot

• Programmer- comes up with step-by-step plan to solve the problem, then writes the program in the computer

• Robot- Carries out the exact plan given to it.

So How Do we Create These Steps?

A robot is simply going down a list of pre-programmed behaviors.

Behavior- Any task you want your robot to perform.

- Behaviors range from simple behaviors (run a motor) to complex behaviors (solve maze)

So we are in control of the robot… so how do we get t to do things we want it to do.

• We must tell it exactly what to do, at a certain point for a certain amount of time

• Two steps to making the robot complete a task:1. Write out the behaviors, or the actions we want

the robot to do2. We then convert our behaviors to words the

robot will understand- called code (puesdocode)

Activity

2 Person Activity- 1 Person is the robot/ 1 Person is the Human (or Programmer)

Challenge: The programmer must walk the robot through the maze without touching/ going over the sides

The Constraints:• The robot will be blindfolded• You can only use “color” commands to direct the robot

Activity Procedure

• You and your group member will designate a specific command to a color:– Example: Blue= Move forward 1 step, Red= Turn left

• Write down your commands and memorize them together- the robot will need to know what each command means

• You and your partner will raise your hand, I will blindfold the robot, and you can “test” your plan

• If you step out of the boundary or on the boundary, you must get to the back of the line

• If need be, modify your commands to make them more specific or easier!

• If you have time, try both mazes!

Today

GLUE THE SHEET IN YOUR NOTEBOOK. PLEASE DO NOT TOUCH THE ROBOTS!• Activity- Everybody completes either (or both) human

maze challenges– Sit down in assigned seat when finished

• Groups for Programming• Wiring: Supplying power to the robot

Wiring Robots- VEX Cortex

• The Cortex isn’t only the “brain” of the robot, but it also supplies power to the motors and sensors you attach to it.

Sections of VEX Cortex

Digital Ports

Analog Ports

Sensor Section

Motor Ports

Battery Port

On/ Off Switch

The motors currently can not run with the VEX Cortex

• Looking at the end of the motor wire, there are only 2 “prongs”- the VEX Cortex needs three wires to run

VEX Logic- Motor Converter Wires

Sole Purpose- Convert the two- prong motor wires into compatible three- wire prongsWith this, we can plug it into the VEX Cortex

How To Use

1. Make sure the motor wire has two straight prongs

2. With metal facing metal, plug male into female

How To Plug Into Cortex (it will only fit one way)3. Rotate wire so “lip” is

facing the inside of the VEX cortex.
