FIRST Tech Challenge is a student-centered program that focuses on giving students a unique and stimulating experience. Each year, teams engage in a new Game where they design, build, test, and program autonomous and driver operated robots that must perform a series of tasks. They also cultivate life skills such as: • Planning, brainstorming, and creative problem-solving. • Research and technical skills. • Collaboration and teamwork. • Appreciating differences and respecting the ideas and contributions of others. To learn more about FIRST Tech Challenge and other FIRST® Programs, visit www.firstinspires.org. FIRST Tech Challenge is MORE THAN ROBOTSSM! While competing, students develop personal and professional skills they will be able to rely on throughout their life. FIRST® Tech Challenge PushBot v4a Build Guide| 7 Gracious Professionalism® - “Doing your best work while treating others with respect and kindness - It’s what makes FIRST, first.” FIRST Tech Challenge Core Values FIRST asks everyone who takes part in FIRST Tech Challenge to uphold the following values: • We display Gracious Professionalism® with everyone we engage with and in everything we do. • We act with integrity. • We have fun. • We are a welcoming community of students, mentors, and volunteers. • What we learn is more important than what we win. • We respect each other and celebrate our diversity. • Students and adults work together to find solutions to challenges. • We honor the spirit of friendly competition. • We behave with courtesy and compassion for others always. • We act as ambassadors for FIRST and FIRST Tech Challenge. • We inspire others to adopt these values. Gracious Professionalism® FIRST uses this term to describe our programs’ intent and is shared with all young people engaging in FIRST programs. At FIRST, team members help other team members, but they also help other teams. Gracious Professionalism® is not clearly defined for a reason. It has different meanings to everyone. Some possible meanings of Gracious Professionalism include: • Gracious attitudes and behaviors are win-win. • Gracious folks respect others and let that respect show in their actions. • Gracious Professionals make valued contributions in a way that is pleasing to others and to themselves. In FIRST, Gracious Professionalism teaches teams and student participants: • Learn to be strong competitors, but also treat one another with respect and kindness in the process. • Avoid leaving anyone feeling as if they are excluded or unappreciated. • Knowledge, pride and empathy should be comfortably and genuinely blended. In the end, Gracious Professionalism® is part of everyday life. When professionals use their knowledge in a graciously and individuals act with integrity and sensitivity, everyone wins, and society benefits. Watch Dr. Woodie Flowers explain Gracious Professionalism in this short video. The PushBot Guide There are three versions of the Push Bot. PBv1 (created in 2014) used the NXT and Samantha units for control and communication. PBv2 (created in 2015) was introduced cell phones to replace the NXT Mindstorm and Samantha units. Modern Robotics modules were introduced to replace the HiTechnic controllers. PBv3 (created in 2016) used the same electronics as PBv2, but had a lower center of gravity. PBv4 is being created in 2017 to introduce the Rev Robotics Expansion uploads/Management/ pushbot-build-guide-vertical.pdf
