2. Teachers and BEST
A major obstacles in the recruitment of teams for BEST competition is making teachers comfortable with the technology involved.
The consumable materials involved in the six-week timeframe are major hindrances in this.
Substituting Pitsco’s Tetrix equipment ( for the BEST consumable kit lets teachers create and program their own robot in the space of a single day.

4. Students and BEST
Pitsco’s Tetrix equipment can be used with students as well as teachers.
Students unfamiliar with BEST can become quite familiar in a relatively short period of time.
Students already familiar with BEST can explore new possibilities.
A week-long summer camp is ideally suited to this.

6. Tetrix Equipment chassis elements gears wheels axles servo pivots
arm elements
motor mounts
screws, nuts, etc.

7. Programming Tutorial Begin with simple program (e.g., “Hello, world!”)
Add arcade control of wheel motors
Add reading of digital input
Add conditional action based on digital input
Add servo control
Connect bumper switches (“Roomba”-style autonomous behavior)

9. Extending BEST’s Impact
Teachers can also be introduced to the use of sensors non-standard for BEST.
White/black detection (line following)
Distance sensor (obstacle detection)
Audio sensor (hearing)
Encourage teachers to encourage students to parlay BEST experience into a science fair project.
