My daughter has just assembled the EdCrane and programmed her Edison robot with the sample program. https://www.edscratchapp.com/?share=5DMQ3XDw

She used the barcodes to set up four arrow buttons on our remote control.

Up arrow = remote button 1

Down arrow = remote button 2

Right arrow = remote button 3

Left arrow = remote button 4

After getting everything set up, two of the buttons work as expected, and two do not.

Up arrow: spins right motor forwards, but also left motor backwards

Down arrow: spins right motor backwards

Right arrow: spins left motor backwards, but also right motor backwards

Left arrow: spins left motor forwards

We've tried the default program. We've tried adding some blocks to stop the other motor. We can't get the motors to behave independently of each other.

Any suggestions on how we can debug this?

Hi Jonathan,

Below I have attached a program that I wrote which I have just tested and can confirm it works correctly.

There are a few differences in the code that we have produced. The structure that you had in your program looked correct to me, I have just brought it all back to the main line instead of having it in the event. I also clear the remote code data every time the Edison receives a new message.

Thank you, Isaac. I still can't figure out why the original version didn't work for us, but your code does resolve our issue.

Heads up

The Australian Federal Parliament has passed a law that extends goods and services tax (GST) to low value imports of physical goods imported by consumers from 1 July 2018.

This means that all customers purchasing Edison robots and accessories with an Australian shipping address must now pay GST. The GST will be automatically added to your purchase and show as a line item on your invoice.

We've detected that you are in Australia, so we wanted to let you know that we have changed your settings to view our Australian site, which displays GST inclusive pricing.

OK got it!    Take me to the GLOBAL SITE instead
