Voice controlled robot car

The wiring scheme on page 119 is different from the wiring scheme on page 123.

I tried both of them. At last, I have the motors turning but I had to use the 3 battery pack to give enough power to make it move a little. It looks like one engine is somewhat weaker than the other so it moves in a circle.

Could you provide the aia of the apk. I am a App Inventor user and would like to make a Dutch version. A lot of the time Google doesn't understand the backward command.

Actually, it is the same wiring scheme on both pages. The car will run perfectly if you use AAA batteries with a triple battery pack. It is a flex project for application on the phone. You can find the Dutch version on Google Play Store.

This is red, black, black, and red.

This is black, red, black, red.

In the photo, you use a double battery pack. This could be confusing to users.
