9. Getting the Cart to Turn

Getting the Cart to Turn! Go Full Screen to see in greater detail?

So far we now know how to:

1. Get the Cart to Move forwards.
2. Stop the Cart and get it to move backwards.
3. Attach a Lamp and get it to Flash.

Now we have to think about getting the Cart to Turn.

Turning the Cart

This is achieved by:

1. Switching ONE motor OFF for a period of time.
2. Then Switching the Motor ON again to stop turning. (we would switch motor A Off to turn Left and motor C to turn right)

Watch the movie to see how this all comes together.

The movie shows the cart going forwards for two seconds and then turned left for 1 second before continuing forward for 2 seconds.

What you have to do!

1. Plan your program by completing Task 14 in your Robolab Progress Extension Grids
2. Start the Robolab Software - if it isn't already open..
3. Create the program and transfer it to the cart.
• If you run out of space you can carry your icons down onto another line.
4. Once the program is working correctly Tick Off Task 9 in the main Robolab Progress Grids.
