Goal: Robot able to pick up and shoot power cells in the inner goal, fit under the trench, and do a chin-up on the generator switch at the end of the match.
Competitive Advantage: Ability to lift a short partner/buddy robot off the ground after climbing ourselves.
Significant Challenges: Fitting a three-stage climber able to reach the 63″ switch under the trench height of 28″.
Inspiration: Over-the-bumper intake similar to our 2016 robot. The telescoping climber was also inspired by Skittles (although that robot never officially climbed during a match).
Configuration: Low profile, power cells enter and leave on the same side of the robot, adjustable hood angle for multiple shooting locations.
Result: 17 power cells scored in a single match, high percentage of inner port shots. Triple climbed with partners in three matches.
Goal: Create a multi-purpose robot capable of scoring both game pieces and climbing to the highest level during the endgame.
Competitive Advantage: “Beak” senses presence of hatch and automatically opens to hold the game piece in place. Internal elevator lifts the robot inches to get onto the platform.
Significant Challenges: Extending our intake beyond the bumper left it vulnerable to damaging contact. We made our intake arms out of resilient polycarbonate.
Inspiration: Had an intake similar to 2014’s Chuck. Level 3 climber was inspired by elevators on 2018’s competitive robots.
Configuration: Double-ended; Cargo intake on one side of the robot and hatch mechanism on the opposite. Climber integrated into structure of robot.
Result: Level 3 climb occurred in all but three of our matches. 12 game pieces scored during tele-op in our best match.
Goal: Create a robust robot that is laser-focused on scoring floor-level cubes – from the portal to the opponent’s switch, from the pyramid to the exchange.
Competitive Advantage: Quickly secures both switches so our alliance partners can concentrate on scale scoring.
Significant Challenges: Packaging multiple systems into smallest footprint that fits below the height of the portal, managing matches where our partners cannot score on the scale.
Inspiration: Tiny robots from SteamWorks that could complete one task more quickly than their multi-function counterparts.
Configuration: Conveyor pivots upwards from drive base to allow gripper to place cubes from the floor into the switch.
Result: Scored thirteen total cubes in one match (combined switch and exchange).
Goal: Create a multi-purpose robot capable of scoring gears, scoring in the high efficiency boiler and climbing onto the airship.
Competitive Advantage: Adaptable to different styles of play – from cycling gears to popping in a few fuel to break a tie.
Significant Challenges: Packing all systems into the volume restrictions including five systems just for fuel (pick up, elevator, sorter, indexer, and shooter).
Inspiration: 2012 robot Shifty’s elevator for collecting and raising fuel.
Configuration: Hopper pivots upwards from drive base to allow full access to electronics.
Result: Climbed successfully in more than 90% of matches, scored a side goal and ten fuel in the same autonomous.
Goal: Create a low bar capable, multi-defense defeating, high goal shooting robot capable of scoring 21 solo points per match.
Competitive advantage: Fast cycler able to traverse four classes of defenses to secure breach points, and contributes boulders to weaken tower.
Significant challenges: Fitting all mechanisms under low bar height, camera vision system to identify high goal targets, drive train able to traverse all defenses.
Inspiration: Wide intake from 2014 robot Chuck.
Configuration: Scorpion-themed rear intake with forward shooting system with height under 14.5″.
Result: Solo breach defences, or contribute six boulders to tower points equivalent to 80 points.
Goal: Create a “HP-fed stacker” class robot capable of stacking and scoring three totes in 60 seconds.
Competitive advantage: Optimizes use of the game’s most restrictive resource (human player chute) by allowing almost constant introduction of totes through chute door, creating a buffer stack of totes on opposite side of wall.
Significant challenges: Fit three robots into transportation configuration, unobtrusive tether, how does a stationary robot contribute during autonomous?
Inspiration: Material handling industry up-stackers.
Configuration: Three-part tethered robot to take advantage of relaxation of robot size constraint.
Result: By the end of season to be able to score two capped (recycling container and litter noodle) six-stacks plus eight individual totes for a total of 100 points per match.
Goal: Create a highly accurate “finisher” class shooter capable of scoring one exercise ball in autonomous and three cycles in tele-op, total solo capability of 42 points per match.
Competitive advantage: Prioritized drive base, then ball acquisition, and then launcher. Identified non-defend-able sweet spot on the field for low risk, highly repeatable shooting.
Significant challenges: Finding a sufficient power source for catapult (multiple passes of spearfish gun tubing), premature wear of catapult shifting mechanism.
Inspiration: 2011 FRC robots (advantages of catapult vs. wheeled shooter).
Configuration: 6WD drop center wide configuration, intake opposite release.
Result: 28 for 28 two-ball auto at Champs, solo capability of 75 points.
Goal: Create a nimble “sniper” class frisbee shooter capable of scoring nine discs and low hanging, capable of scoring three discs in mid-goal per match.
Competitive advantage: Prioritized drive base, then disc acquisition, and then shooter. Calibration jig allowed tuning of high goal shot prior to matches.
Significant challenges: Packaging of wheeled shooter within frame perimeter.
Inspiration: FLL (use of field elements to localize/orient robot).
Configuration: 6WD, low enough to pass below pyramid bottom rung.
Result: Repeatable three-disc autonomous, highly accurate four or five cycle tele-op, fast low bar hang, solo capability of 88 points per match.
Goal: Create a solid “support” class robot capable of acquiring foam basketballs for partner or own use.
Competitive advantage: Prioritized drive base, then ball acquisition, then bridge manipulator, and then shooter.
Significant challenges: Rookie learning curve, mongoose bridge actuator susceptible to damage, temptation to replace passer with shooter in last days of build resulted in raised centre of gravity and inconsistent gameplay.
Inspiration: Robots on www.thebluealliance.com, experience of our macMentors.
Configuration: 6WD skid steer KoP drive base in wide configuration to maximize ball acquisition and minimize bridge balancing footprint.
Result: Shooter capable of scoring low goal (occasionally). Feature list:
