The Claw

The Claw is the main pixel pickup and deposit system.

Rotates to place pixels in front of the robot; no longer a need for the claw to rotate around the robot;
Uses sponges for maximum pixel gripping strength;
Uses goBILDA speed Servo motors.

Previous versions

Claw v1.0

Used SG90 servo motors to hold the pixels in place, which were not strong and could easily break.

The Butterfly Intake

This was the first intake system we designed this season and the 5th version of it was used in V1. It was a horizontal intake mechanism driven by a goBilda 312 RPM motor via mitter gears. The system was great at picking up pixels, but horrible at transferring them, since they could not be propelled upwards after leaving the system. Lesson learned: a vertical intake is better.

Double Decker Intake

This was a vertical intake system designed for V2. It had 3 rollers, all of which were connected by belts. Because it did not have a bottom roller, the pixels were prone to jamming inside the system.

The Tripple Gripper

This was an alternative system dismissed after being used in V1. It was applied to pinch pixels from the inside by 3 grabbers actuated by a mechanism shown on the left. It had a few problems, like needing precise alignment, difficulty depositing 2 pixels at the same time and just being too complex.
