It's the Claw.
As the title suggests, today has been focused around the claw for the robot.
The programmers were still working on the code for the claw. They were "Frankensteining" code: taking one bit of code (that wasn't identified) and transforming it into the code for the claw. Such as working on the codes for the motors for the carriage.
They also were coding for the autonomous mode, and working on a script. The script would allow people who don't know how to code in Java to program the robot from the driver's station.
The mechs attached the second elevator, and were working on adjustments for the tote lift. Which was interesting progress, but not the most interesting. They were also working on the prototype for the claw itself to pick up the recycling cans.
Everyone else? ...They were working on hats. A noble pursuit.
