Axle bearing holes are drilled along the centerline of the 2" face 14.96" apart: 1.125" holes at the pivot point for 1/2" flanged bearings; 7/8" holes at the wheel end for 3/8" flanged bearings. Bearings are installed with the flanges on the rectangular tube interior. Each axle possesses a 22T Al HTD5 flanged pulley (inside the rectangular tube). A xxxmm HTD5 belt (also inside the rectangular tube) connects the two pulleys and transfers power from the pivot axle to the wheel axle. |

Like DEWBOT X's Roller Frame, this simple yet versatile system performed multiple roles in competition, including:Functions
- Pulling/guiding RCs into the robot lift
- Stabilizing RCs for transport once acquired
- Pulling/guiding totes into the robot
- Aligning totes on the floor to lift position
- Preventing first Human Player Station tote from landing its side
- Aligning first Human Player Station tote to lift position
- Aiding correct alignment of subsequent totes loaded from the human player station
- Correcting any subsequent tote misalignments which may occur
- Stabilizing the tote/RC stack during transport and scoring
Design
The system is comprised of the following components:
- A pair of Intake Arms with Intake Wheels
- A robot floor shaped to align totes drawn into the robot for lifting
- A pair of fiberglass rods anchored to the robot floor and passing through holes in the lift positioned to prevent totes from sliding too far back for correct lift alignment
