Aerial Assist

2014 FIRST Game

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.

Simbot Evolution

Simbot Evolution Robot

Drivetrain

  • Riveted aluminum sheet metal chassis​
  • Six wheel drive utilizing 4" x 1” VEXpro traction wheels
  • Powered by four CIM motors; power transmission via custom two speed transmission, utilizing VEXpro ball shifter components and roller chain drive​
  • Approximate top speeds of 5.7 ft/s (in low gear) and 13 ft/s (in high gear)
  • Drop down VEXpro 4" omni wheels to assist with getting out of t-bone pins
  • Wheelie blocks to move tipping point fulcrum out and closer to the ground, making the robot more difficult to tip

Shooter

  • 2 pairs of 4” x 1" VEXpro traction wheels with 3/16” fabric backed urethane riveted to the circumference
  • Each pair driven by two RS-550 motors through a custom gearbox with a 4:1 reduction and VEXpro belt/pulley power transfer
  • Theoretical free speed linear velocity of 88 ft/s
  • Two 3/4” bore, 8” stroke cylinders accelerate the ball into the shooter wheels
  • Each cylinder has a designated high flow solenoid and working pressure accumulator to maximize actuation speed
  • Surgical tubing retracts cylinders to reduce air flow restriction

Intake

  • 2” dia PVC tube covered in paint-on urethane with wooden plugs, driven by nylon hex shaft
  • Powered by shooter gearbox with a 30:18 VEXpro belt/pulley reduction
  • Theoretical free speed linear velocity of 25 ft/s

Claw

  • Driven by VEXpro BAG more through 50:1 VersaPlanetary gearbox
  • 12 DP sheet metal gear attached to claw for additional 7:1 speed reduction
  • 24 DP 3D printed gear attached to claw frame for potentiometer feedback
  • A pocket is designed into the claw sheet metal to maximize the height in the robot’s starting configuration, maximizing the release height of the ball
  • Two sheet metal tusks are used to help center the ball, along with adhesive backed foam and teflon
  • Two plastic tubes prevent accidental contact between the ball and shooter wheels

Control

  • ​Multiple pre-set claw angles and shooter wheel speeds for various shooting positions around the field
  • Claw angle controlled by PID controller with position dependent power limiting to optimize pickup and position holding
  • Bang-bang controlled shooter wheel RPM for rapid spin-up and accurate shooter velocity
  • Hot goal detection during auto, utilizing on-board camera
  • Encoder and gyro based feedback for reliable autonomous driving and positioning

The Indiana Robotics Invitational (IRI) is an off-season Robotics Competition event, hosted in Indianapolis. It began in 2000 with 21 teams, and is now one of the premier events in the world. In 2011, 114 teams applied to compete at IRI, while only 66 teams were invited and accepted. We would like to invite all teams who wish to compete, but we simply cannot. The mission of IRI is to host an enjoyable, high quality, and well-organized Robotics Competition event, bringing together top competitive and strong character teams from across the community. The IRI is a family-friendly event that is open for all of the public to attend. Competitors are invited to attend after filling out an application to compete. Teams are invited after being evaluated on numerous qualities. These qualities include past seasons; performance and impact at IRI, current season performance at Regionals and the Championships, and other extra-ordinary team aspects which will enhance the IRI event. Since 2008, some teams applying to compete at IRI were not invited. This is simply due to the demand of teams wishing to attend compared with the limited size and time needed to run IRI. We invite these teams to attend as spectators and encourage them to still enjoy the event. Thank you to all of the teams who make IRI an outstanding event. More

Greater Toronto East Regional

-

Team 1114 and Simbot Evolution began their 2014 season at the Greater Toronto East Regional in Oshawa, Ontario. We began the qualification matches strong, earning a score 420 points in our first match of the year. With a record of 8-0 by the end of friday, we were constantly battling for first seed against Team 3683, in some instances, prompting the third tiebreaker to determine which team was on top.

Collecting two more victories on Saturday morning, we became the number one seed, and created a powerful alliance with teams 3683 and 4718. After a victorious... More
