Bumpers
Build code-legal bumpers — pool noodle on plywood — and a threaded-stud mount that swaps fast and won't fall off.
01
Bumpers
Bumpers protect the robot's perimeter — pool noodle over plywood.
- Two 2.5 in pool noodles on a 5 in tall, 3/4 in plywood backing.
- 3/4 in ground clearance; ~1/4 in gap to the frame.
- Exact cutout/clearance rules change yearly — check the game manual.

Model Them Separately
Keep bumpers in their own component.
- Sketch the bumper profile in the main layout sketch.
- Make a dedicated bumper component (origin reference first).
- Sweep the profile around the drivetrain edges.

Mount Them
A threaded-stud mount swaps fast and stays put.
- 3/16 in aluminum bracket with a slot for the stud.
- Pocket for the nut that retains the bumper.
- Four mounts around the perimeter — more for multi-piece bumpers.
