Scribbler S3
Scribbler S3
Launch into programming and robotics basics with this beginner-friendly tutorial series and the Scribbler 3 Robot. This series has been divided into three consecutive sections (described below) to guide you linearly through the tutorials whether you're in the classroom, or DIY-learning at home. We strongly recommend you follow these tutorials in order unless you're an experienced roboticist who is familiar with both BlocklyProp and the S3 Robot

Make this track
Here are some possible troubleshooting solutions:
Remove the stop driving block. Occasionally, the sensors read a "false positive." Removing this block can help.
Eliminate the gaps by trimming the paper, or by filling these gaps using a Sharpie® or black masking tape.
Improve your program by making it more tolerant of gaps in the line or by programming it to find the line again. Such a solution would allow you to use unmodified line following tracks like page 7 from the pdf resource.
Try the first two solutions outlined above, in order.
Run tests and observe how your S3 performs on the line following track for each. How did the solutions work? Which did you prefer?
Using your code as a starting point, try a different block from the ACTIONS > MOTORS category for the left and right functions. Can you make the S3 move more smoothly? What did you do?
Your Turn
Add Obstacle Sensor Blocks (Obstacle Sensor)
