Step 2¶
- Drag the “set left wheel speed and right wheel speed” into the
On start
brick.
Step 3¶
- Set a
Sonar
variable to save the detectedCm
value in theForever
brick. - If the detected value is between

and10
, the car stops moving. - If the detected value is below
5
, the car reverses because of the short distance with the hands. - If not any, the car moves forward to catch up with the hands because of the far distance with the hands and then stay still .
