2014 – The Mammoth

The Mammoth was designed to play Aerial Assist, FIRST’s game for the 2014 FRC competition. Check out our teaser video above.

THE MAMMOTH 2014

DRIVE TRAIN

  • 28” square base with 6 AndyMark 6” high-grip wheels
  • Two 3-CIM toughboxes (powered by 2 CIMS per side)
  • 10.5 ft/s single-speed transmission

INTAKE MECHANISM

  • Pneumatic-actuated with gravity driven lift (for easy low-goal scoring)
  • VexPro high grip wheels for instant contact and traction
  • Intakes ball directly into awaiting tusks
  • Wheels positioned to support ideal curvature of the ball

BALL ELEVATOR AKA “THE TUSKS”

  • Designed to conform to the ball (for catching from the truss and HP)
  • Mounted on custom clockwork axle which enables shooting both forward and backward
  • Pneumatic-actuated, disk brake system designed to stop tusks at ideal shooting height (for greatest range)
  • Mounted on same pivot point as swing arm for consistent ball launching from various distances
  • Maintains ball control under lateral force

WEIGHTED SWINGING ARM MECHANISM

  • Fully-actuated arm allows for close-range truss shot and “super shot”(shooting the ball in excess of 30 ft.)
  • Fixed-angle shot with variable exit velocity, enables shooting range from 5-15 feet away
  • Can also shoot (backward) into the high goal anywhere from 1-3 feet away
  • Supports “light kick” for low goal shots and gentle passing
  • Mounted on same pivot point as the tusks to create fully-integrated system for consistent shooting

PROGRAMMING & CONTROL SYSTEM

  • Uses camera and custom dashboard to recognize target and regulate exit velocity for optimized shot to target
  • Backswing angle measured using encoder, height of the tusks measured using linear potentiometer
  • All image processing/calculations performed on driver station with final targeting data returned directly to robot

AWARDS

  • Xerox Creativity Award at Mid-Atlantic Robotics FRC Region Championship
  • Engineering Excellence Award at MAR FIRST Robotics Bridgewater-Raritan District Competition
