Game Discription

Aerial Assist is played by two com­pet­ing Al­liances of three ro­bots each on a flat 25’ x 54’ foot field, strad­dled by a truss sus­pended just over five feet above the floor. The ob­jec­tive is to score as many balls in goals as pos­si­ble dur­ing a two (2)-minute and 30-sec­ond match. The more Al­liances score their ball in their goals, and the more they work to­gether to do it, the more points their Al­liance re­ceives.

Official Game Rules

AER­IAL AS­SIST is played by two com­pet­ing Al­liances of three Ro­bots each on a flat 25’ x 54’ foot field, strad­dled by a light­ing truss sus­pended just over five feet above the floor. The ob­jec­tive is to score as many balls in goals as pos­si­ble dur­ing a 2 minute and 30 sec­ond match. The more Al­liances score their ball in their goals, and the more they work to­gether to do it, the more points their al­liance re­ceives.

The match be­gins with one 10-sec­ond Au­tonomous Pe­riod in which ro­bots op­er­ate in­de­pen­dently of dri­ver. Each ro­bot may be­gin with a ball and at­tempt to score it in a goal. Al­liances earn bonus points for scor­ing balls in this mode and for any of their ro­bots that move in to their zones. Ad­di­tion­ally, each high/low pair of goals will be des­ig­nated “hot” for five sec­onds, but the or­der of which side is first is ran­dom­ized. For each ball scored in a “hot” goal, the Al­liance earns ad­di­tional bonus points.

For the rest of the match, dri­vers re­motely con­trol ro­bots from be­hind a pro­tec­tive wall.  Once all balls in au­tonomous are scored, only one ball is re-en­tered in to play, and the Al­liances must cy­cle a sin­gle ball as many times as pos­si­ble for the re­main­der of the match. With the sin­gle ball, they try to max­i­mize their points earned by throw­ing balls over the truss, catch­ing balls launched over the truss, and scor­ing in the high and low goals on the far side of the field.

Al­liances re­ceive large bonuses for “as­sists,” which are earned for each ro­bot that has pos­ses­sion of the ball in a zone as the ball moves down the field. Points are awarded for each ac­tion per the table be­low/to the right

Our Robot

General Robot

Our ro­bot, Hermes, is well rounded, both of­fen­sively and de­fen­sively, with a catcher, shooter, and blocker. The ro­bot’s catcher can ex­pand to give us 40 inches of more space. The drive sys­tem al­lows both high torque and high speed. We de­signed our shooter as a cat­a­pult.

  • Height 59.5 in
  • Width 27.5 in
  • Length 28 inches
  • Light­weight cus­tom on-board com­pres­sor al­lows us to store twice the on­board pres­sure as pre-match com­pres­sion sys­tems
  • Versa frame and alu­minum item con­struc­tion

Drive

  • Tank drive
  • West coast set up
  • 6 4-inch wheels with co­ef­fi­cient of fric­tion of 1.2
  • Cen­ter wheels dropped 1/16 inch to al­low for eas­ier turn­ing
  • Two speed gear­box with a gear ra­tio of 5.60:1 in high gear and 16.36:1 in low gear giv­ing ap­prox­i­mate speeds of 15.0 ft/s and 5.5 ft/s
  • Uti­lizes four CIM mo­tors each with 337 watts of power

Pickup

  • Roller ac­tu­ated to twenty inches out­side of frame with two, five inch stroke, pneu­matic cylin­ders do­nated by SMC

Catcher

  • PVC frame ac­tu­ated by two eight inch stroke pneu­matic cylin­ders
  • Catch­ers ac­tu­ate out 18 inches be­yond frame to al­low for max­i­mum catch­ing area and ac­tu­ate in­side the frame to avoid ac­ci­den­tally catch­ing an op­po­nent’s ball

Programming

  • ‘Cul­ver Drive’ sys­tem uses an­gle of turn­ing stick to pro­vide a more in­tu­itive in­ter­face to dri­vers.
  • Hot goal de­tec­tion abil­ity al­lows the ro­bot to make 10 point au­tonomous shots with very high ac­cu­racy
  • Au­tonomous pro­vides for both se­quen­tial “ac­tions” and long term back­ground tasks.
  • De­tects which goal is hot
  • Dri­ves for­ward, and shoots
  • Dri­ver sta­tion in­ter­face al­lows us to pro­vide the dri­vers with real-time in­for­ma­tion on the ro­bot sub­sys­tems, in­clud­ing the sta­tus of the on­board com­pres­sor.
