Who We Are


Team 20 conists of Bryan Yong and Yuriy Brun. We are juniors at MIT in course 6-3.

The Contest


This year's contest consisted of an unleveled field with two goals and 14 balls, 7 of each of two colors. The object of the game was to push balls into the goals (holes in the table). The first ball to go into a hole is worth 1 point, the second 2, and so on. For more information on the contest, click here.

Our Strategy


Team 20's strategy is a clear winner. Our robot is built small and powerful. It can start at one end of the table and drive across the entire table in under 3 seconds. The robot's strategy is to turn towards the nearest gutter, score the 1 ball closest to us and then turn parallel to the gutter and fly to the other side of the table, blocking the second scoring hole. The entire strategy can be executed in under 6 seconds, keeping the chances that the other team has enough time to score 1 ball before we block the goals very low (scoring 2 balls in that time is practically impossible).

The Robot


The robot uses tank stearing. It have two driven wheels and two coasting wheels. The friction of the driven wheels is increased by the rubber treads. There are 2 motors driving each of the two wheels using a gear box with a reduction ratio of 25:1. With that set up, the robot has tremendous power to accelerate to its maximum speed quickly.
The robot uses 4 light sensors, all hidden below its soft lego belly. One is used to recognize the start light and three more to orient the robot at the beginning of each match. Three red LEDs are used to help the robot recognize its surroundings.

The Battle's Aftermath


Unfortunatelly, our robot did not win a match because one of the motors, mounted by hot glue, came loose in competition. Our record is 0-2, but are spirits are still high.
