EV3 robots are approaching end-of-life and will not be sold after June 2021. We encourage you to purchase Spike prime robots as we transition.
This competition will involve two robots in a circular ring, with the goal being to push your opponent out of the ring or otherwise disabling them within the time limit. While pushing your opponent out of the ring is the most common way to win a round, disabling your opponent (flipping, lifting, etc.) is strongly encouraged.
Teams for a tournament will consist of 1 or 2 students. A student may only be on one team. Each team will use one robot and robots cannot be shared between teams.
Eligibility for the State STLP SumoBots Competition is not determined by the SumoBot winners from FCPS STEM Fair. Each school in FCPS may register up to 1 team per school for the State STLP SumoBots Competition regardless of their school's performance during FCPS Spark Fair.
The event will take place on a 4’ diameter smooth plywood ring, painted black, with a 2” wide white border to help the robots determine the edge of the ring. The ring will be raised 1 ½” above the floor (3- 2x4 blocks) to help determine when a robot has “fallen off” (generally determined by the robot touching the ground outside the ring).
Robots are to be constructed of 100% LEGO brand parts - this does not limit the robot to only LEGO parts shipped with the kit.
Lego Spike, EV3, and NXT robots are allowed to compete with the possibility they will compete against each other.
No glue, melting or modification of LEGO brand parts is allowed.
Only sensors that are supplied with LEGO NXT or EV3 sets can be used. Any combination of sensors can be used - not limited to the number shipped with the original kit.
Only one (1) Intelligent brick and up to three (3) motors are allowed.
Robots are to be completely autonomous after the bout is started (no human input).
Robots must fit within a 12" x 12" square. There is no height limit. EXCEPTION: Robot may expand beyond its 12" x 12" size once the bout begins.
Robot must not exceed 2.2 lbs.
Robots cannot be modified after inspection.
The front of the robot is determined by the placement of the sticker (inspection).
No piece of the robot should be designed to deliberately become detached (causing debris in the arena).
Programming: The first block of the program must be a five second wait block. This five second wait block gives all students time to move back away from the board.
Robots must move during the match.
Robots will begin with their rear wheels on the starting lines.
If there is entanglement during two bouts with no scoring, then at the judge's discretion a different starting position may be used for the third bout. Example: starting front to front or the same direction.
Stalemates: In the case of repeated stalemates, the referee will determine a winner based on his/her judgment, favoring the robot taking the most offensive actions. It is advisable to have alternate programs to run to avoid repeated stalemates.
Each school is allowed to enter 1 team which consists of 1 or 2 students.
A student may only be on one team.
Each team will use one robot and robots cannot be shared between teams.
