Buggy Task 6:

This is a simple task that runs the buggy forward for 2 seconds and then runs it in reverse.

One of the most important features of the Intellecta system is the worksheets that assist in planning the solution. The worksheets hide the details inside and encourage the designer to plan the system in a top-down approach.

The strategy is simple - just place two worksheets on the workbook and make them run for two seconds. The time is set in the property of the worksheet that is set to be “independent” This means that the sheet runs and then starts the next one.

The start input comes on the input stub on the left of the sheet.

The functions of the icons are:

Forward - this icon generates a fixed output that is selected in the icon property.

Rvse-  generates a fixed reverse value.

How to open up the insides of the worksheet

The insides of the worksheet are accessed through the Window menu. Select this and the menu will show the names of the worksheets that are on the workbook.

To Select a worksheet:

Click on the name. The contents will be shown. Use the Tile, Cascade or Arrange Icons to show all the worksheets in a staggered view.

Inside the Forward worksheet

Place the icons inside the worksheet to follow the same Task as in Task 5. Motor 1 and Motor 2 are controlled by two Set-point icons that generate a fixed on and reverse value.

Notice that the Light icons are labelled as Light> and Light<.

It is always a good idea to document the strategy with as many labels as possible. It makes debugging and finding problems much easier.

Inside the Reverse worksheet

Place the icons inside the worksheet to follow the same Task as in Task 5. Motor 1 and Motor 2 are controlled by two Set-point icons that generate a fixed on and reverse value.

Notice that the Light icons are labelled as Light> and Light<.

Notice that the order of the Set-point reverse and Set-point Fwd icons are reversed from the previous example.
