2018 Greater Boston District Event Newsletter
Our team with our second blue banner
We competed at the Greater Boston District event in Revere, MA, on the 7th and 8th of April. It was held at Revere High School. After 12 qualification matches, we finished with a record of 9-3, seeded #4 out of 42 teams and finished winning the event and the Industrial Design Award. We qualified for the New England District Championship and are competing this week to qualify for the FIRST World Championship in Detroit.

SCOUTING

Pit and robot scouting went really well at this competition and we were able to gather some really useful information for alliance selections. Scouting data led us to success by providing us with intel about each robot and allowed us to sort them into a list of robots that we wanted to partner with for the elimination matches. As the 4th seeded team we had to have our pick list ready.

NEW FEATURES

At this competition, we changed our climber. The climber was unique compared to others as it had two long hooks at a slight angle and proved to be enough to latch onto the bar and climb. It worked smoothly and consistently.

We also added a new feature to our robot to help us hold on to the power cubes without dropping them. The shelf is a bent piece of polycarb that attaches to our intake with a hinge. This was an amazing and game changing addition to CATWOMAN because the robot did not drop cubes when we were trying to lift the cubes up.

COMPETITION MATCHES

During qualifications, a robot fell on us during a climb, bending one of our drivetrain's frame rails, leading to a frantic attempt to find a way to repair the rail before our next match. We ended up snapping the rail with a metal bar and had to use gussets and a support bar to brace and hold together the new “joint”.

In autonomous mode, our robot is programmed to detect the colors of the scale and the switch so our robot picks the correct autonomous mode. For instance, if the switch is blue on the right and we are on the blue alliance our robot will drive and align itself to put two cubes on the blue switch.


During alliance selection for eliminations, we were picked by the #1 seed Team 125. Together we utilized scouting data to select our 3rd alliance partner Team 4311 the Swampscott Currents. Throughout the playoffs, autonomous modes worked very well and were able to control both the switch and scale at the start of the match, gaining us some very valuable points. For most matches, the strategy was to have 125 control the scale while 4311 to control our switch and fill the vault. We controlled the opponent’s switch and played defense.

AWARDS

Our team presented our Chairman’s Award submission for the third time. Even though we did not win, we felt this was our strongest presentation yet. We had some tough competition this year, and we look forward to working harder to create a stronger submission next year.

We won the Industrial Design Award. The judges said:

“This team’s robot represented a synthesis of clean design and efficient operation. The cube manipulator had its drive system cleverly concealed in its structure. The robot was the only one with a gear shifter in the elevator which provided an appropriate balance of speed and torque for lifting cubes and climbing the scale. The team’s attention to the machining and assembly processes throughout the prototyping phases resulted in a simple, yet deliberate design of a reliable and easily serviceable robot. Two cubes or eight, the robot could do it all.”
