1. Introduction to programming consistent results
Beyond the basics
Introduction to programming consistent results

3. Things to consider when building your robot
What missions to go for
Complexity of the robot
Time Constraints
Consistent Starting position
Navigation and Alignment needs

4. How the sensors work
Ultrasonic Sensor- good for stopping at a distance and wall following
Color Sensor - Good for stopping on a line and line following
Touch Sensor - Good for stopping at a wall or object
Gyroscopic Sensor - Extremely sensitive when resetting, good for turning and angle following

5. Programming Considerations
Stopping the motors versus using a sensor to stop at a point
Straight motor driving versus measured “following” driving using sensors - three different ways with three different sensors
Using motor rotations to move versus using the gyroscopic sensor

6. Programming examples
Wait blocks for stopping at a point

7. This is a basic black/white line follow
This is a basic black/white line follow. We are not following the line, we are following the edge of the line. This may not work exactly for you as displayed. Your motors may not be in these ports and they may be reversed or upside down.
Also remember the color sensor is very sensitive to ambient light.

8. Things to remember:
Always check your ports, especially if you have unexpected results.
Reset your sensors before you use them to measure.
The distance you travel is dictated by the size of your wheels.
Don’t be afraid to experiment, your team will learn by failing.
There are many different ways to solve challenges, don’t get stuck using just one way. If it not working, start over with a different approach.
Read the Coach’s manual and check for game updates regularly.

9. Conclusion
There is more than one right answer, in fact there are infinite possibilities, so don’t get stuck
Keep lots of notes and pictures
Balanced team
Read the Coaches manual, the challenge, the rubrics and the core values
