Robotics assessment - practical and evaluation

While you are doing the practical you need to keep a record of successes, failures, problems, reasons for problems/failures, and how you solved, or could solve, them.

Remember you are not writing a new post, just continuing with the previous one!

You should already have on your Robotics assessment post the first planning write-up from the planning lesson. 

At the end of this lesson your Robotics assessment post should have the following things on it:

1.  A photo of the course.

2.  A correctly shared diagram of your programming flow chart (remember extra marks are available for using decision diamonds and/or sub routines).

3.  A description of your successes and failures in the practical, how well your team worked together and any problems with the teamwork (no names, please!).

4.  A description of how you could improve your success by improving the programming to compensate for any robot inaccuracies, robot problems, how the team worked, etc.

5.  If I was able to video your group's robot, you will need to make a copy of the video to your Google drive, shared it and add a link to that video as well.

The greater the detail - the greater the marks!!  Impress me!

Once this is all done to the best standard to you can, publish!

Robotics Assessment - Planning

Here are some hints for what you need to do to plan for your assessment for the Robotics unit.

Here is a photo of the course/arena that you have to program your Wall-E to go round.


The rulers are in the photo to act as a guide to how far apart some of the walls are and how far your Wall-E will have to travel.  Each wheel rotation is approximately 15cm so you can see from the photo where there are whole 30cm rulers and some half rulers showing.  This is a rough guide to the number of wheel rotations you'll need to program.

You'll be using the ultra-sonic sensor on your Wall-E (which is his eyes) and you must make sure the cable from his eyes goes into port 4 on the control box.

Think carefully about the programming and whether you need to include a loop (repetition or subroutine) to help make your program run smoothly.  You want him to go round the course without you having to press any buttons!

You need to write the following on your Blog post:
1.  A description of the task 
2.  A copy of the photo of the course
3.  Draw a flowchart showing your program for this course.
4.  A link to your flowchart.

You are going to write up just one Blog post for this whole assessment! 

This means you have to Save at the end of each lesson - 
DO NOT PUBLISH YET!!!

Robotics lesson 2 - Selection

Selection lesson notes

For your Post for this lesson you need to:

1.  Explain what Selection means and give an example of how it can be useful (I used logging on to the network as my example)

2.  In Google Draw - draw your flow chart for the lesson's challenge (move forward 1 rotation if not touching anything, turn around if touching something).

3.  When this is finished, share (Anyone with the link) and copy/paste the link to your Blog post (don't forget to highlight the link text and click on the blue Link button).

4.  Say whether you managed to get your Wall-E to follow the program and work correctly.  Any problems?  Say what they were and how you overcame them.  Can you link this selection task to another lesson or other work we've done before? (jam sandwich!)  if so, say how it links up (Level 6!) 

5.  Find your group's photo of your Mindstorm program and copy/paste it to your blog post.

5.  When all this is done - Publish your post!
