Version 2 – FTC Decode Development - CENTERSTAGE

V2 Concept

V2 Concept

In the second version of the robot (V2), the main focus was on precisely arranging the balls...
In the first version, we faced issues with ball instability...
Embracing balls and preventing random movement
Organizing ball arrangement before launch
Improving ball transfer path inside the robot
Ensuring consistent and repeated shooter feeding
The goal was not just to launch the balls...
Intake System

Intake System

Design

Flexible sticks to increase intake range
3D printed intake unit (first stage)
6 rollers powered by a single motor
Improving intake efficiency and reducing failure
Challenges
Need for precise balance between flexibility and strength
In some cases, the ball may not enter smoothly if the angle is not suitable
Spindexer System

Spindexer System

V1 vs V2

V1: Poor ball embracing
Random ball movement inside the robot
Unstable ball position before launch
Inaccurate shooter feeding

V2 Improvements

Design that embraces balls and prevents movement
Servo rotates balls at 120° angle
Directing each ball to the launch position in an organized manner
Challenges
Need for precise adjustment of rotation angles
Any misalignment affects ball arrangement and feeding
Shooter System

Shooter System

Design

Turret system allows 360° rotation
Gear system: Driver 30 - Driven 100
Balance between speed and torque

Main Components

Internal plates (Ball-Contact Components)
3D printed connector + speed gear
External plates (main structure)
Ball guide plates
Mounting base and rotation support
Rotation platform and gears
Challenges
Shooter vibration due to imprecise flywheel mounting
Slight loss in RPM due to using gears and chain instead of direct drive
