FIRST® Robotics Competition (FRC®)
Scouting Builds Winning Alliances and Winning StrategiesA working robot, a great drive team, and thorough scouting -- all three are required to win
A working robot + a great drive team = only one third of your 3-team Alliance
Scouting accounts for fully two thirds of your Alliance
In the FIRST® Robotics Competition (FRC®), no one plays alone!
Who will you choose and why?
Who will choose you and why?
One of the most important competition aspects of FRC, scouting other teams, is too frequently overlooked. Especially, when teams are new or have few members and limited resources, but even a mediocre robot can win with great strategy built on great scouting.
- Knowing your opponents strengths/weaknesses wins matches
- Knowing your alliance partners strengths/weaknesses wins matches
- Knowing your own strengths/weaknesses wins matches
Picking partners and setting match strategy based on randomly watching matches leaves you with bad impressions of robots that made phenominal efforts when you were out getting lunch and were crippled by a field error when you happened to see one of their matches. Scouting is much more than casually watching each match to see one robot that is better than the others. While the crowds are oooing over one flamboyant play, your scouts need to be watching the other robots to find the solid performers in the bunch. One flamboyant play will stick in the minds of casual observers and make them want to pick that robot, but forget that robot's mediocre performance the rest of the day. The audience will remember a robot broke down and forever think of it as undependable even if it turns out to have been a field error. Good scouting lets you pick out that under appreciated robot that scores or defends consistantly and brings home a steady dependable match every time even when the rest of their alliance under performs and they lose the match and end up way down in the rankings. At the end of qualifiers 8 teams will be picking 16 other teams and if you only remember that the guys in the top 8 had good robots, how are you going to pick the other two robots that will account for two thirds of your strategy and scoring?
Why is Scouting so important?It's part of a plan that succeeds year after year, because it affects:
- Match-by-Match Strategy: For effective strategy your drivers need to know what to expect from alliance partners as well as opponents in any match.
- Alliance robots: Select partners that can bring home a task better than you, so together you are greater.
- Alliance strategy: Select partners that complement a general strategy you plan for the finals, e.g., score or defend.
- Marketing: Promote your own team based on your strengths. Use real data to prove what do you do better than anyone
- Future designs!: Gain from the creativity of 50 to 1500 other teams. Spearhead an engineering analysis of:
- What designs worked best,
- How they were countered,
- What strategies succeeded/failed,
- What might fit with your tools/talents/skills,
- What can you improve on,
- What should you strive for?
Face it, even if you never expect to finish in the top eight, you'd at least better understand what other teams look for in a partner. Be the partner they want, do what they can't do, be easy to work with, be strong and accomodating in strategy, perform consistantly, be dependable, don't draw penalties.
Even if you're playing for fun and don't care who wins you still need a way to choose partners, especially if your friends have already been chosen by someone else. Picking based on final standings may get you a lucky partner or a good robot that doesn't work well with yours. Every year an unprepared rookie ends up in the top eight through luck of the draw, or unexpected skill at the game. There's nothing worse than being forced to choose teams to play with and not having a remote idea of how teams (other than the top 8) have been doing. You need a plan, a list of teams to chose from, and even just knowing who's still available. There's nothing more embarrassing than trying to pick the guy or gal who's already been picked. Either scout or practice your "deer-in-the-headlights" look.
Types of Scouting
- Internet scouting (FIRST team database, team websites, Chiefdelphi, Blue Alliance)
- Robot photos
- Match video (The Blue Alliance)
- Basic data
- Preliminary capabilities
- Team history of performance and reliability
- Pit scouting (roving packs of scouters)
- Talk to pit crews (drive teams too if you can)
- Take current robot photos
- Collect data on type of drive train, power (# of motors), wheel traction material, manipulators, complex or simple design, etc.
- Visually observe robots and pits. Does a robot seem to be under repair a lot? Do they have ready to go spare parts & assemblies?
- Collect robot information sheets describing robot capabilities, past performance, special characteristics
- Talk to other scouters (robot capabilities/record)
- Match scouting (sedentary group of scouters)
- Collect results, both subjective (defense success, speed, stability, drive team skill) and objective (points scored, mechanical reliability, penalities)
- What did they do in autonomous/hybrid. Will you interfere with one another as partners? Can they disrupt you or you them as opponents?
- Drive team impressions easy/hard to work with, cooperative/uncooperative
- What strategies defeat them?
- What strategies do they defeat?
- Remote event scouting (after the fact for robots you'll compete with at upcoming events)
- Match Records
- Detailed analysis, a la, 2008 Team 1114 Championship Database
- Decide what you want to know about each robot.
- Make simple pit & match scouting sheets.
- Watch, even visit, early regionals if possible to see what other data you missed
- Ask the coach/drive team/match strategist what they want to know each match.
- Train your scouters on Practice Day or match video from early regionals.
- Assign a scouter to every robot on the field for each match of the day (one or more people).
- Collect photos of every robot to prompt your memory later.
- As data comes available brief your drive team on partners & opponents for each match.
- Debrief drive team for impressions/details after each match.
- Review your data after the first day of Qualifiers.
- Discuss pros & cons as a group with the photos to remind everyone.
- Develop preliminary “best” lists that complement your robot & anticipated strategy. May be best offensive robots and best defensive robots.
- Watch the robots on your best lists during the last qualifying matches.
- Refine and finalize your lists. Don’t forget to watch for late bloomers – robots that finally get it together after a rough beginning.
- Send your Team Captain to Alliance picks with your final lists, even if you aren’t doing the picking. Compare lists for that all important third pick overlooked diamond.
- Joint Alliance briefing/strategizing on finals matches.
Some Issues to Consider
- Scout yourself as well as others to know where your real strengths and weaknesses lie
- How will you evaluate robot performance & reliability, drive team teamwork, and strategy
- Head Scouter must be well organized
- Scouts must be trained so every report is consistent in how performance is rated.
- Keep it simple
- Your scouting should match your people resources.
- Counts and multiple choice answers are easiest to sort and analyze team performance. Essay and freeform write in answers are only good as backup material.
- Paper records vs computerized
- Paper never fails. It's easy to pull a team summary from and pass around, but is hard to sort and analyze all teams by different criteria
- Computer requires resources and data entry can be time consuming. Data can be forever lost. Convenient power outlets can be hard to come by. Very useful for displaying current robot photos.
- Save team performance, reliability, cooperation data year-to-year to build up a history for future seasons
Team 358 Scouting ProgramHere's a brief Team history of our scouting growth over our years of play.
Team 358 switched over our scouting program to be Microsoft Access based in 2005, the year of the tetra. It's not overly complex or difficult to collect data for, and it will run on any PC with standard Microsoft Office loaded.
Here is the simple system for 2005: Team 358 2005 Scouting Program
Subsequent years have been modifications and upgrades of the same basic system to add more analysis sophistication, although we strive to simplify in search of repeatable, successful results. Every year also has it's own game challenges and the data we decide to track does change.
- Set of properties we keep track of are each assigned a decision weight reflecting their importance to us
- Individual scouting reports for each robot in each match are entered and maintained
- Analysis allows us to sort teams based on any property, such as, maneuverability, points scored, defense played, penalities
