  1. FIRST Team 4188 Concept Design Review Columbus Robotics Alliance January 8, 2014

  2. Problem Statement • Played by two competing Alliances of three robots each on a flat 25’ x 54’ foot field, straddled by a truss suspended 5’2” above the floor. On each end of the field is a high and low goal. • Each alliance’s objective is to move a 2’ exercise ball from one end of the field to the other, using as many robots as possible, to score the ball as many times as possible in available goals in the 2 min. 30 sec. time frame. • Design Parameters: the robot can be no more than 120 lbs, with extensions-- 20” max— deployed from the base footprint (112” maximum total perimeter), no taller than 5’, except for defensive robots with restricted mobility • Points are awarded for: • Throwing the ball over the 6’2” upper limit of the truss (10 pts), catching the ball afterwards (10 pts) • Scoring the ball in the high goal—opening 6’11” to 10’ above ground—(10 pts) or the low goal—cube elevated 7” (1 pt) • Passing, or giving “Assists”, from one robot and zone to another (10 pts per assist) • Driving forward in the autonomous period (5 pts) • Bonus: scoring in a ‘hot’ goal=2x pts, scoring a goal during autonomous (+5 pts) • This year’s game, “Aerial Assist”, prompt video: http://www.youtube.com/watch?v=oxp4dkMQ1Vo

  3. Low Goal: in order to score, the ball must be propelled by the robot into the cube, and cannot touch the robot and goal at the same time The four high/low goals available per alliance . Yellow LED lights lining the margins of each goal indicate if the goal is ‘hot’ The truss, located in the middle of the field 2’ diameter ball For assist points to be counted, an alliance robot MUST score a goal (high or low) at the end of field.

  4. Derived Requirements: at 3 weeks • Drive: drivetrain optimized for speed, maneuverability, and control. Side-to-side motion ability preferred. • Possession: The robot will be able to control the ball and quickly (14 ft/s) deliver it to another point on the field.

  5. Derived Requirements: Final Design • Catch: capture airborne balls from wide range and direct to propulsion /tossing mechanism. Extensions used for this purpose must not exceed lengths of 20” from 112” max perimeter robot footprint • Retrieve: rapidly (within 2-3 seconds) and efficiently possess balls on the ground, with minimal chance of unintentional loss. Internal storage capacity preferred. • Toss/Propel: Accurately and powerfully propel ball to low goal and other alliance members. Precision, accuracy, and speed optimized. • Defense: Optional capacity to prevent opponent from scoring • Wiring: route/manage all circuits, wires, and pneumatic tubing • Appearance: vision lights, sponsor panels, decorations • Protection: attach legal bumpers • Integration: ensure all systems and subsystems operate together
