2017 High School NEOREP Competition - Penguin Bot Race
The theme of the 2017 NEOREP High School competition was "Penguin Bot Race". Teams had to design a robot that would navigate a Le Mans-style course, following a line through some hairpin turns as well as travelling through a maze on the table. Both games were scored by travelling through as quickly as possible. Additionally, teams had to create a technical journal, documenting the process of creating the robot solution, write a research section on the science and math involved in car races, and make a five-minute presentation to a panel of judges.

The MK III was specifically designed for top performance at the 2017 NEOREP competition. It utilizes two large EV3 servo motors and five Lego-brand sensors (three color, one gyro, and one ultrasonic). The chassis design is loosely based off of the Lego driving base model, which places the motors side by side and under the EV3 brick. The robot has a “hood” that lifts and gives access to the gyro and light sensors. The light sensors are arranged so that the black line lies between the two outermost ones. They are programmed to measure the reflected light intensity, only seeing black and white. The middle sensor is programmed to register the red circle at the end of the course and stop the robot. The gyro sensor is tucked between the motors for two reasons: 1) it doesn’t need a direct line of site to measure anything like distance or color, and 2) it maximizes the use of what would otherwise be wasted space under the robot. Between Game 2 and 3, the robot has to “go through the pits” for a slight modification; the color sensor that is plugged into port 1 is unplugged and replaced with the gyro sensor. The use of the Lego Technic Ball Caster Wheels (Lego part # 992185) allow for the robot to be bi-directional. The robot travels with the red hood facing forward for Game 2 and for Game 3 forward travel goes with the ultrasonic sensor with the Viking helmet facing forward. This bi-directional approach to designing our robot not only makes our team stand out amongst the crowd, but essentially combines two separate robots into a single chassis design.

2016 High School NEOREP Competition - Rube Goldberg Design
This year's competition was different from what we've seen before. NEOREP 2016 incorporated more of the science, engineering, and math in STEM by building a Rube Goldberg Device. Our robot would drive up and over a ramp located in one corner of a 4'x8' sheet of plywood. As it passed the fulcrum, the robot would drive over a light switch turning on a light on the opposite corner of the table. Our job was to turn off the light using a minimum of 4 energy transfers.

The robot rolls over the light switch and turns on the light. After turning on the light, it drives forward and (A) pushes the 1st class lever that is hooked up to the linkage system and raises the platform holding the tennis ball up. The ball rolls down the inclined plane and strikes the end of another 1st class lever (B), which pulls out the trap door (C), releasing the ball bearings down the spiral tubing (D). The ball bearings collect in the cup (E), and once filled moves the stopper in front of the magnetic levitation train. The maglev train travels down the inclined plane and passes in front of the ultrasonic sensor (G) which activates the scissor lift (H), raising the platform with the tennis ball up, which then rolls down the last inclined plane, hits the switch, and turns off the light. A video of our competition can be found here.
2017 Middle School NEOREP Competition - Penguin Bot Race
The theme of the 2017 NEOREP Middle School competition was "Penguin Bot Race". Teams had to design a robot that would travel two laps around a NASCAR-styled oval track as well as navigate a Le Mans-style course, following a line through some hairpin turns. Both games were scored by travelling through as quickly as possible. Additionally, teams had to create a technical journal, documenting the process of creating the robot solution, write a research section on the science and math involved in car races, and make a five-minute presentation to a panel of judges.

ALPHA-1 was specifically designed for top performance at the 2017 NEOREP competition. It utilizes two large EV3 servo motors and four Lego-brand color sensors. The chassis design is loosely based off of the Lego driving base model, which places the motors side by side and under the EV3 brick. The light sensors are arranged so that the black lines from Games 1&2 lie between the front sensors. They are programmed to measure the reflected light intensity, which will determine if the robot is on black or white. There is also another sensor in the middle of the robot behind the front three, which is utilized to find the red circle at the end of Game 2 and stop the robot. It’s positioned between the two drive motors. On the front of our robot is a windscreen shield, which is designed to push air up and over the car and the rear wheels are Lego Technic Ball Caster Wheels (Lego part # 992185), allowing the robot to make intricate turns with ease.

The robot rolls over the light switch and turns on the light. After turning on the light, it drives forward and (A) activates the ultrasonic sensor which (B) rotates the two motors pulling the strings and releasing marbles (C) down the inclined planes. The marbles go through the plinko board (D) and collect in a cup attached to a 1st class lever (E) which sends a ball down (F) the three inclined planes. The ball hits a door (G) which activates an ultrasonic sensor causing the motors to raise the RoboVikes flags (H), tripping another ultrasonic sensor that pulls (I) the ramp holding up the running race car (J) which drives forward and hits the button, turning off the light. A video of our competition can be found here.
