FRC1675 The Ultimate Protection Squad is proud to present our 15th creation, SHARKBAIT
Drivetrain
- Custom 6-wheel West Coast Drive
- 6” Wheels - 2 AndyMark HiGrip, 4 VexPro Omni
- ⅛” center drop to provide option to go to 6 traction wheels
- 6-MiniCIM WCP SS Gearboxes Geared to 17.61 ft/s free speed (8.68:1 Ratio)
Tiltavator
- Greyt lift inspired 2-Stage Cascade Lift powered by MiniCIM w/ 16:1 VersaPlanetary Gearbox to reach all levels of rocket
- Elevator tilts forward from starting position to align manipulator at correct height over bumper for human player station and low goals
- Tilt is actuated using 2x 2” bore, 6” stroke pneumatic cylinders
- Elevator positively engages with chassis rail when tilted forward to maximize stability
- Elevator can return to storage position to allow for defense
Hatch-Slinging Slapper: Mk. 1
- Hook and Loop-based manipulator
- Pivots to slap hook and loop panel on ground to allow for dropped hatch-panel acquisition
- 3x 1-1/16” Bore, 2” Stroke Pancake Cylinders to release hatch panel
- Home and ground pick-up positions controlled by 2x 1-1/16” Bore, 7” Stroke pneumatic cylinders to easily maintain the two critical positions
Hatch-Slinging Slapper: Mk. 2 (Not pictured)
- Design was updated after issues discovered during Week 0 practice competition
- Ground-pickup geometry maintained from Mk 1 design
- Design of pivot supports modified after buckling noticed after limited use of Mk 1 design
- High grip hook tape replaces standard hook tape to firmly grasp the hatch panels
- Actuated Hook added to create positive engagement when retrieving hatch panels from human player station
- Hook sits behind main panel when stored to prevent interference during ground pickup
- Hook actuated by 2x 9/16” Bore, 2” stroke pneumatic cylinders
- Front panel tilts up to 20 degrees in either direction using a passive, spring loaded design to assist with small misalignment when placing Hatch Panels
