ROBOTICS Jason Bell Brad Carlson

 EV3 is the third platform Lego ® has created for robotics  Platform 2: NXT can still be used but is no longer supported by Lego, however it can still be programmed using the EV3 Mindstorms software  Two parts to all robotics; Construction (what do you want your robot to do) and Programming (how will your robot do it?)

Robotics promotes and/or supports  Mathematics - angles - problem solving -algebra -chance and data  Science - simple machines - force and motion  Digital Technologies – Creative thinking

 Whilst allowing students to create a robot is fun, engaging and interesting, you will get a multitude of designs that may or may not meet the intended purpose. When starting out use a simple design for all students/groups, the activity will have more purpose and run a lot smoother.  For this reason today we are using the basic design you have prebuilt to allow more hands- on time

1.Open LEGO Mindstorms 2. Click the “+” icon to open a project tab 3. Rename your program

Working in the program is simply click, drag and drop. Programming is icon based. Icons are located at the bottom of the program window. Each icon will change once it has been placed to give a number of variables associated with the that icon eg. power, volume, distance. You can collapse or expand the “Document your work” dialogue box by clicking on the Mindstorms logo next to the pencil.

 Connect the robot to the computer via USB cable  Click this button  Wait for confirmation beep  Disconnect cable and run program

Click and drag a “Large Motor” icon to the programming pallet, placing it next to the “Play” building piece. The icon will change to look like the one below. The functions for the motor are all shown on the icon with drop down menus. Output port A/B/C/D Motor power level Motor variable Brake/coast Motor on for…

Use Trial and Error make your robot turn 180 o Does wheel rotation equal robot rotation?

Program your robot to 1. Travel forwards 5 rotations 2. Travel backwards 3 rotations 3. Complete a sharp right-hand turn 4. Complete a slow left-hand turn 5. Travel forward 3 seconds and then backwards for 2 seconds 6. Turn exactly 90 o

Pick a sound file to play File name is displayed in upper right corner

Infrared Touch Light Ultrasonic Gyroscope Compass

Unlimited (default) Time Sensor

“Wait for Time” Allows the robot/program to complete one task before moving to the next or by defining a delayed start time for an action.

Challenge: Program your robot to greet someone as they walk past

On the floor are a cup-ple (please laugh). Your robot must complete a figure 8 around the cups.
