GEAR 3rd Year Junior Lessons - 2021

Third year Juniors will work on programming an Edison robot. This page contains a list of lessons you should complete in the Edison Activity Book

How Do I Program the Robot?

We will start learning to program Edison by using the EdScratch programming environment. EdScratch works in your web browser. In your web browser enter this address to load EdScratch: or use this link. We suggest that you bookmark this webpage in your browser because you will need to use it every time you write a program for the robot.

My Edison Robot is not working - what should I do?

For trouble shooting assistance with Edison robot, see this page:

If your robot was working but now has stopped working, its batteries may need to be recharged. We would be happy to provide you with a set of fresh batteries if you drop the robot at the La Favre front door. Just let us know when you plan to come. We will change the batteries while you wait.

You can also charge the batteries yourself if you have a charger designed to charge nickel metal hydride (Ni-MH) batteries. Please insure your charger is designed to charge Ni-HM batteries. Alternatively, you can use four AAA batteries bought at the store, but only if they are of the ALKALINE type. Changing the batteries can be a bit tricky. Slip a fingernail underneath one of the tabs on the battery cover at the back of the robot to open the battery compartment. Remove the batteries. Insert the fresh batteries, as seen in the photo below. THE BATTERIES MUST BE INSERTED IN THE PROPER PATTERN IN ORDER TO AVOID IRREPARABLE DAMAGE TO THE ROBOT ELECTRONICS. After all four batteries are inserted part way into the compartment, then push them all the way in and replace the door

Online lessons from Edison Robot company

The lessons you will complete are in a book available online at this link:     We suggest that you download a copy of this book to your computer. Below is a list of the lessons you should complete.

IMPORTANT! Some of the pages in the book should be printed and these are listed. The pages to print are the worksheets, where you answer questions. When you complete the worksheets for a lesson, take a photo of the pages (or scan them) and send them to Mr. La Favre. He will check your work.

Lessons that require additonal equipment

Up to this point you have not been assigned exercises that require more than one robot or extra equipment. Now that you have learned most of the programming for the robot, you can go back and do the exercises that require additional equipment. GEAR has a limited number of Edison robots. If we have an extra one available, you can check out a second robot. GEAR also has some EdCreate kits and you may check out one. Many of the exercises listed below also require a TV remote control. If you don't have a TV remote control, you can borrow one from GEAR.

Pages 17-18   U1-1.2c Change it up: TV remote control barcodes, print p 17 and activity sheet U1-3 (page 34)
The exercises that utilize the EdCreate kit require that you control the robot by TV remote control. This exercise teaches you how to program Edison to receive coded information from your TV remote. Don't worry, this will not make any changes to your TV remote. It will still work properly in controlling your TV.

Page 20   U1-1.2e Challenge up: Build and control the EdTank, print p 20
requires two robots and EdCreate kit and remote

Page 21   U1-1.2f Challenge up: Build and control the EdRoboClaw, print p 21

Page 144   U4-1.4a Challenge up: Build a pulley, print p 144.
If you do not have an EdCreate kit or Lego parts, just imagine that one of the Edison robot wheels is a pulley. Just make one of the Edison robot wheels behave like a pulley as suggested in this activity.

Pages 165-167   U4-2.5 Let's explore messaging with Edison, print p 166.
This exercise requires two edison robots. However, you do not need to work with a partner.

Do you want to learn a new programming language?

When you have completed the lessons using EdScratch, you might want to go on and learn another way to program Edison. Edison can be programmed with EdPy, which is based on the popular programming language named Python. When you start learning Python, you begin a journey that will allow you to do advanced programming.

GEAR advisors have not selected a series of EdPy lessons for you at this time. Nevertheless, you can check out EdPy at this web site:
