2020 Season
Finalized Robot
Sting
"Sting" was the final iteration of our robot used in the 2020 FRC "Infinite Recharge" game. The components used for Sting from this portfolio include the:
V1.3 Frame
Magazine System
Shooter System
Preseason
Demo Mecanum-Drive Chassis
Designed as practice in preparation for the 2020 FRC season. Driven by 4 Falcon motors each connected to a mecanum wheel.
Demo Swerve-Drive Chassis
Designed as practice in preparation for the 2020 FRC season. Driven by 4 Andy-Mark Swerve Modules.
FRC Lifter
Designed in preparation for the 2020 FRC season. This lifter would be powered by a single NEO motor, with 5 rolling sprockets and 1 stationary sprocket to drive a roller chain. The included components are primarily from McMaster-Carr so the design can easily swap components.
Frames
V1.1
Similar to 1014's 2019 chassis design, this frame was designed with a front opening, and a "West Coast" tank drive wheelbase, meaning that the center wheel is lowered slightly.
V1.2
Identical drivetrain to v1.1, however removes the front opening and keeps all drivetrain wheels leveled. To compensate for excess friction when turning, the two front traction wheels were replaced by omni-wheels.
V1.3
Same as V1.2, but updated with changes to flange sizes, wheelbase slots, and wheelbase depth. Includes additional dimple-die holes and drivetrain attachments.
V1.3 Renders
The V1.3 was the final chassis iteration to be used in the 2020 season. The frame was fit to be 32" x 27" x 5.25", and used 8in wheels for the tank drivetrain, 2 omni-directional wheels and 4 traction wheels.
Video Demo: Using the Linked-Parameter Table
The entire chassis design was created such that a table of certain primary dimensions could be altered, and the all assembly components would adjust to match the changes made (demonstrated in the video above).

Launcher System
Launcher
Launcher Half-Section
This launcher was designed to shoot the 7" diameter foam balls by spinning up an 8in traction wheel driven by a Falcon 500 Motor. Sheet metal with clear, polycarbonate backplate to guide the ball from the lower entrance to the

Magazine System
Magazine
Magazine Half-Section (Filled)
This magazine was designed to take the 7" diameter game balls from the gatherer, and feed them into the shooter system. There are a series of compliant wheels inside that drive the balls entered from the bottom of the magazine to the exit at the top of the magazine. The conveyor-like mechanism was driven by a 1:15 ratio 775pro Motor, and is built out of sheet metal and has a clear, polycarbonate backplate.

Manufactured Prototype
The function of this design relates to the 2020 FRC game season, where teams have a task of intaking a 7" diameter ball from the field. This design accomplishes this by using a perpendicular belted design, and being placed about 7" from the ground. The ball can be either grabbed by the front roller (~24"), or the side rollers (~8"). Once the ball is underneath the intake, there are belts running horizontally across that are oriented to drive towards the center, no matter which side the ball is on. Once the ball is in the center, the perpendicular belts then have the traction on the ball, pulling it into the chassis the intake is mounted onto.
2019 Season
Frames
V1 Chassis
The first version of our 2019 FRC chassis, it was used for driver practice and as a guide for the other components that would be added on.
V2 Chassis
This second version of the 2019 FRC chassis was the one that was used in team #1014's 2019 FRC season. The robot was awarded the 'Quality Award' sponsored by Motorola at a regional competition.
