Design Lead
Led the end-to-end mechanical design for Diablo's Intake. Designed in Onshape, the robot featured a full shooting turret with Limelight auto-aim, a dual four-bar intake, and a two-stage climber — capping the season as Texas State Champions.

JONAH'S DESIGNS
Intake Mechanism
Dual four-bar linkage that operates both passively and actively — motorized retraction with surgical tubing passive tension for rapid "touch it, own it" ball capture.
- → "Touch it, own it" rapid capture design principle
- → Passive four-bar + active motorized retraction
- → Limit stops for both extended and retracted positions
- → Three dead-axle rollers span ball width for secure capture
- → Surgical tubing provides passive closing force without motor load

COMPONENTS
Dual four-bar linkage forms the deployable intake that swings the roller assembly out from the frame perimeter. Geometry is tuned so two Falcon 500 motors retract the intake against passive surgical-tubing tension, with hard stops defining both deployed and stowed positions.
- → Dual four-bar geometry keeps the roller bar parallel to the floor through full travel
- → Motorized retraction overcomes passive tubing tension for controlled stowing
- → Hard stops at both extents define repeatable deployed and retracted positions
- → Linkage envelope sits within the bumper perimeter when fully stowed
Three dead-axle rollers wrapped in grip tape span the full ball width. Driven by a Falcon 500 through a 1.33:1 reduction, the assembly supports the "touch it, own it" capture principle by pulling balls in the instant they contact the rollers.
- → Three rollers span ball width to prevent off-axis capture
- → Dead-axle design eliminates cantilevered motor-shaft load
- → Grip-tape wrap maintains compliance and friction across the ball surface
- → Single motor drives all three rollers via shared belt path
Dead-axle architecture lets the rollers rotate around a stationary thunder-hex tube that runs the full width of the intake. Because the hex tube itself never spins, it can be clamped on both sides to act as a primary structural cross-member rather than just a shaft.
- → Dead axles allow the rollers to rotate around the thunder-hex tube, leaving the hex tube entirely stationary
- → Thunder-hex tube is secured on both sides — provides cross-panel structural support, not just a roller mount
- → Single round tube adds a second support path between the side plates
- → Mounting blocks on either side of the round tube secure it along more than one axis
