-  Send radio number in `1` when pressing button A. 
- Send radio number in `2` when pressing button B.
- Send radio number in `3` when pressing button A+B.

- Drag "show icon" brick into the `On start` brick and set the "radio set group" to `1`. Items must be the same with the remote control for the correct match.
- Drag three "if" bricks into the `on radio received` brick and judge if the received number is `1`,  `2` or `3`.
- When the received number is `1`, turn left.
- When the received number is `2`, turn right.
- When the received number is `3`, go straight.
