The Mission

The fundamental challenge of engineering design is solving problems while meeting basic physical constraints. This year ME72 students formed teams to design, build, and operate, under manual and/or autonomous control, a team of 3 robotic vehicles that can:

Competition Tasks

• Compete and withstand the physical rigors of a robot soccer matches played within a 24-ft x 48-ft arena in the Brown Gym.
• Operate autonomously during a 20 s period at the start of each match.
• Operate under radio control for a 4-minute period and successfully navigate the field and barriers, while collecting, and shooting size-1 soccer balls into designated goals at opposing ends of the field.
• Collect and secure as many soccer balls as possible and deposit or launch them into designated goals in order to accumulate as many points as possible during a match.
• Defend their goals and attempt to prevent opponents from scoring.
• Outscore their opponent robots and be the last team standing at the end of the extended double elimination tournament.

Design Challenges

• Each team will field up to 3 robots at a time, which are operated under radio control by team members stationed along each side of the playing field.
• Matches are played with twelve (6-in diameter) soccer balls on the field at any given time and teams must earn points by depositing soccer balls into any one of 3 goals stationed at each end of the playing field.
• The playing field features a central tower with ball release mechanism, and an elevated barrier, which spans the width of the field and divides the playing field into 2 zones. A tunnel beneath the tower provides passage between the two primary field zones.
• Robots can drive the length of the field by going through the tunnel or crossing the center elevated field divider.
• At the start of each match robots will autonomously race toward a release mechanism (switch) positioned on their side of the field, which is designed to release the remaining four balls from the holding bin.
• Teams then assume radio control of their robots for a 4-minute period and attempt to score as many goals as possible from anywhere on the field.
• As balls are scored, they will be promptly removed from the goals by field attendants and placed onto a return rail. The balls reenter into play on the opposite side of the field from where they were scored.
• As robots attempt to score they must also deal with opposing robots that may be defending their goal.
