Spartan Fleet
Named team builds across past and current V5RC seasons. Each robot has its own page with build logs, decisions, port maps, and engineering notebook references. The fleet's naming convention follows two predator families: long-necked waders (Heron, Crane, Stork, Skimmer) and arc-strike birds (Osprey), with raptors (Kite, Owl, Falcon) for the speed-and-precision builds.
🔒 Private — for Team 2822
Team 2822A's competition build. Front roller intake for pins lying down; rear swing-arm with polycarb tube for pin/cup loader handoffs; flex-wheel toggle. Inspired by 355Z's Simple Bot Override 2-bar architecture — optimized for fast scoring through mechanical simplicity.
Team 2822C's competition build. Tall rear tower built from three vertical C-channels split into two bays: right bay holds a four-bar lift with V5 claw (2×11W inline); left bay holds a flex-wheel toggle (1×11W). Battery and brain on left for COG balance. Bill-and-pouch metaphor: V5 claw is the bill, alignment cavity at chassis front is the pouch. Descends from the Osprey chain-bar baseline but converged on four-bar.
Team 2822D's competition build (V1.5 four-bar with center tower). The unique spin: a 5.5W gear mechanism rotates the V5 claw independent of the lift, letting the team flip pins on their hex faces, invert upside-down cups, and order pin-on-cup combos deliberately during transit. Toggle architecture: two flex wheels mounted on the chassis rear face, spaced 14″ apart; both contact the same 26″ toggle bar simultaneously when the robot backs into the perimeter wall, giving 2-point grip for higher rotation reliability per engagement. 88W exactly at cap with 10 motors. The orientation-and-flip specialist of the fleet; sister-bot to Pelican and Osprey in the V1.5 family.
Team 2822E's competition build (V1.5 chain-bar variant). Single chain bar on a 13″ center tower sweeps 180° between two chassis cavities — back-cavity at the loader, front-cavity over the goal. Static-sprocket geometry holds manipulator level through the arc. Pneumatic pincer or polycarb tube on the chain bar tip (team chooses). Dual-side mirrored toggle (2 × 5.5W) for any-side wall engagement without chassis reorientation. 77W total — 11W spare. The committed-cycle, mechanically-simple sister to Pelican's four-bar lift.
Team 2822F's competition build (V1.0 baseline). Structurally the closest-to-baseline V1.0 build — recommended drivetrain with cavity, four-bar lift, V5 claw on the mounting template, flex-wheel toggle. The architectural divergence is in power transmission: the two 11W lift motors drive a shared output shaft that powers both the four-bar arm (geared 5:1 for torque) AND the flex-wheel toggle (stepped up 1:2.67 for speed) via different sprocket ratios on the same shaft. One motor pair, two purpose-built outputs. 71.5W total — 16.5W spare, the largest headroom in the active fleet. The kite metaphor lives in the power transmission: one anatomy, multiple performance regimes. Joins Osprey and Falcon in the raptor lane.
Team 2822O's competition build (V1.0 baseline via Spoonbill). Inherits Spoonbill's chassis, four-bar lift, and dual rear flex-wheel toggle. The architectural divergence is the manipulator: four flex wheels in two opposing pairs on a pneumatically-pivoting body that snaps between horizontal (for field pickup) and vertical (for loader catch) orientations. Active rolling intake instead of a passive grip — the wheels handle both compression-grip and intake direction. Where Spoonbill rotates the element after grip (claw rotation gearbox), Owl reorients the manipulator before grip (pneumatic pivot). The fifth manipulator type in the fleet alongside V5 claw, pneumatic pincer, polycarb tube A, and polycarb tube B. Joins Falcon, Osprey, and Kite in the raptor lane.
Compound mechanism concept — four-bar lift carrying a chain bar end-effector for both gross lift and reach extension. Named for the long-necked silhouette and the strike-from-stillness behavior. Most horizontal reach in the fleet but capped by SG2 expansion limit.
Six-bar lift concept. Single drive motor delivers nearly twice the vertical sweep of a four-bar at the same arm length, with the manipulator preserved level via the parallelogram constraint. Highest single-mechanism vertical reach in the fleet. Construction-crane double meaning lands the engineering reference instantly.
Double-reverse four-bar concept. Two four-bar stages chain-coupled for synchronized opposite rotation, doubling the vertical travel while folding flat at rest. The fleet's only architecture that combines high reach with sub-6″ stowed height — clears SG12 endgame limit without a separate fold sequence.
Articulating-arm concept. Shoulder + elbow + wrist + claw deliver any-angle reach within a 17″ semicircular workspace from the shoulder pivot. Fastest cycle time in the fleet via the dive-and-strike motion of a falcon on prey. The fleet's lone raptor; balances the wader-bird trio.
