2023 GAME STRATEGY
FIRST Robotics Competition
Team #1799 Wired-Up!
Charged Up
We have been developing and using a process for choosing a game strategy. The following document records our process of making our strategy for this year. Starting with the game rules and scoring chart we developed a list of specific robot behaviors and ranked them by importance and difficulty. From there we brainstormed several possible types of robots we are likely to see in this year’s competition. Then we imagined the best combinations of these robot types and analyzed how many points we predicted each alliance could score. From this analysis we drew several conclusions. With that as a starting point, the team discussed what we wanted our robot to do. The team listed out what we wanted our robot to do during each phase of a match. Identifying how many points we can score by ourselves and how many points we think our alliance is likely to score. From the behavior we defined what we need our robot to do. That became the beginning of our designing of the robot.

What Types Of Robots are Possible
Snailmail: delivers Cone and Cube across the field
Express Mail: High/Low gear deliver CC across the field
Tank Mail: High Traction/armored/carries CC within Perimeter
Bulldozer: pushes Cone/Cube into floor nodes
Forklift: picks up and places cone/cube on level 1 and 2 nodes
Loader: picks up and place cone/cube on level 1, 2, and 3 nodes
Layup: Throws CC to level 2
Longshot: Throws CC to level 2 and 3
Simple: pick up and drop CC, drive, auto, floor node
Blockade: defensive robot - slows down delivery of CC
Possible Alliance Combinations
Assume one robot does charge station during auto = 12 pts. 3 robots charge at end = 30pts
Option 1: 1Snailmail8, 2Bulldozer5, 2Loader6 = 24
Auto: 9+4+4+3+3+3+12 = 38 pts Teleop: 7*3+7*2= 35pts End = 30pts Total = 103
Option 2: 1Tankmail10, 2Loader5, 2Loader5 = 25
Auto: 9+6+6+6+6+3+12 = 48 pts Teleop: 4*5+9*3+6*2= 59 pts End = 30pts Total = 137
Option 3 : 3Longshot8, 3Layup8, 1Forklift4 = 27
Auto: 9+6+6+6+4+4+4+4+12 = 55 pts Teleop: 6*5+5*3+9*2= 63 pts End = 30pts Total = 148
Option 4: 2ExpressMail12, 1Forklift4, 3Longshot8 = 30 = 27
Auto: 9+6+6+6+4+4+3+3+12 = 53 pts Teleop: 6*5+7*3+7*2= 65 pts End = 30pts Total = 148
Option 5: 1TankMail10, 3Longshot8, 3Longshot8 = 33 = 27
Auto: 9+6+6+6+6+6+6+3+12 = 60 pts Teleop:3*5+9*3+8*2= 58 pts End = 30pts Total = 148
Conclusions: Only alliances that can place Cones in row 2 or 3 will get Sustainability. 1 RP
One really good robot might be able to get Sustainability by themself.
2 good delivery and 1 good placing robot is as good as 3 good robots.
Delivery is the most dangerous job. Placing Cones is the hardest job.
Only alliances with 1 robot that can Engage and 1 that can Dock or 3 that can Dock will get Activation. 1 RP
A robot that can Engage autonomously is most valuable to an alliance.
Strategy as of: 1/11/23
Tank Mail
We should make a sturdy little robot that has the power and traction to balance on the Charge Station. We will recieve cones from the SubStation and pick-up cubes from the floor. We will place all game piece in bottom row of the Grid. We will be durable to survive the chaos of mid-field as we transport game pieces or play defense when allied with top ranked teams.
Auto: Place cube move out of community and
- go pick up cube, place cube (Mobility3,Grid3,Grid3)
or
- ballance on Charge Station (Mobility3,Grid3,Charge12)
Teleop: Retrieve CC from SubStation, drive to Community, Place CC in botton row of Grid. (Grid2,Grid2,Grid2,Grid2,Grid2,Grid2)
End Game: Narrow to drive up and leave plenty of space for 2 more robot (Charge10)
With an optimized autonomous program and well practiced drivers we will be scoring enough points to show the top ranked teams we would make a great second pick for their alliance.
With no assistance from Alliance: 18 + (8*2)16 + 15 + 10 = 59 pts
With assistance: 9 + deliver 10 (9*5 + 1*3) + 20 + 10 = 87 points
Activation - 1 RP Sustainability - 1 RP
Robot Requirements based on Strategy:
Balance on the Charger autonomously
Receive CC from Single Feed Station - Dump in Community
Make it easy to pick up a cube on the floor while driving towards it.
Move the cube inside of our perimeter frame when transporting.
Make the robot narrow so it takes up less space on the Charger.
Can Drive Fast. Can make precise movements/turns
