What Is FIRST Tech Challenge?
Get the big picture of FTC: what teams do during a season, how a match is played, and how events, alliances and awards work.
In this lesson you will
- Describe the goals of FIRST Tech Challenge and what a team does during a season.
- Explain the periods of a match and how alliances are formed.
- Outline how qualification matches, rankings, alliance selection and playoffs fit together.
- Recognise that awards reward engineering, documentation and outreach, not only match results.
Lesson
FIRST Tech Challenge (FTC) is a robotics program run by FIRST for students roughly 12 to 18 years old. Each season FIRST releases a new game, and teams design, build and program a robot to play it. The robot matters, but FTC is really about learning to work like engineers: solving open problems, testing ideas, writing down what you learn and helping others along the way.
What a team actually does
- Design and build a robot using kit parts (for example from REV or goBILDA) and parts you make yourselves.
- Program the robot in Blocks, OnBot Java or Android Studio using the FTC SDK.
- Document the engineering process in an engineering portfolio that judges read.
- Reach out to the community, for example by running demos or helping new teams.
- Compete at events against and alongside other teams.
The season at a glance
- 1Game revealFIRST publishes the new game and the Competition Manual. Teams read the rules carefully before designing anything.
- 2Design, build and testTeams brainstorm strategies, prototype mechanisms, build the robot and practise driving.
- 3CompeteTeams attend events, play matches, talk to judges and learn from other teams.
- 4AdvanceStrong performance or awards at an event can earn a place at a higher-level event, such as a regional or national championship.
How a match works
Matches are played 2 vs 2: two teams form the red alliance and two form the blue alliance. The field is 12 ft x 12 ft, made of 24-inch foam tiles, with a wall around the edge. Your alliance partner works with you for that match only; in the next match you may be playing against them. That is why communication and respect between teams are so important.
| Period | Typical length | What happens |
|---|---|---|
| Autonomous | 30 seconds | The robot runs a pre-written program with no driver input. |
| Transition | 8 seconds | Drivers pick up their gamepads and get ready. |
| Driver-Controlled (TeleOp) | 2 minutes | Drivers control the robot with gamepads through the Driver Station. |
| Endgame | Final portion of TeleOp | Special tasks are often worth extra points near the end of the match. |
Events, rankings and alliances
At a typical event every team plays several qualification matches with randomly assigned partners. Results are used to rank the teams. The top-ranked teams then become alliance captains and choose partners during alliance selection, and those alliances play in the playoffs. The exact format depends on the event type, so read the event section of the manual before your first competition.
Awards: more than winning matches
Judges give awards that recognise things like robot design, innovation, programming, outreach, teamwork and the quality of the engineering portfolio. Teams usually have a short interview with the judges where students explain their work. A team that never wins a match can still earn an important award by showing great engineering and Gracious Professionalism. Award names and criteria are published each season in the Competition Manual.
Key terms
- Alliance
- A group of two teams, red or blue, that work together during a match.
- Autonomous
- The first 30 seconds of a match, when the robot runs a pre-written program without driver input.
- Driver-Controlled (TeleOp)
- The two-minute period when drivers control the robot with gamepads.
- Competition Manual
- The official FIRST document that contains the rules for the current season.
- Engineering portfolio
- A short document that summarises the team's engineering process, robot and outreach for the judges.
