Ok. So here is an option if someone has basic sewing machine skills.
Materials:
1)plywood
2)wood screws
3)drill and bit to pre drill holes
4)Carpenters penciled or something to leave a mark that won’t bleed.
5)Cloth of correct colors (16" wide by robot frame perimeter+ (3/4" *4 (for plywood thickness) + (noodle diameter * 8) + a few extra inches(for a 120" frame this would be 120+3+20+extra = 143" + a few extra (so 146ish)
6) tape to temporarily attach noodles
Making them:
-
Plywood ring of correct dimensions for your frame with some reinforcing angle brackets and mounting hardware. Leave room for extra cloth to wrap around (1/8 inch extra on length and width beyond what is needed for mounting hardware is probably fine.)
-
mark on plywood where mounting hardware goes
-
attach noodles temporarily with masking tape
-
this tool from 1x4 lumber, this is a template to help with the corners.
-
each side is the plywood length+ 2 noodle diameters
-
mark out those distances from your starting side (keep in mind to use some of the extra overlap, so, start 1.5" in, go half of side length+ a noodle diameter, make a mark, go the next side + 2 diameters, …, last half side + 1 noodle diameter+ 1.5" overlap.
-
mark using the short side of the tool mirror the profile on either side of the marks you have been making. Something like this (ignore my scribble mistake) , my paper is too small, so the areas labeled “cut” should be little irregular pentagons
-
check the plywood frame with noodles attached temporarily.
-
now you can put the numbers on (carefully about right side up) however you want
-
carefully cut or fold the corners and ideally getting them sewn to resemble this around all corners, then sew the extra overlap together:
-
assemble as you would with any other bumper, holding noodles in place, stapling fabric to wood, etc.
