The kit is a Lego based with Tetrix metal. Additionally, FTC has an expanded allowable materials list so that teams can fabricate parts and custom pieces for their robot.

The following additional components may also be used:
1. Polycarbonate plastic sheet (e.g. Lexan), not to exceed 576 sq. inches total area, 24" maximum dimension, and not greater than 0.10" thick.
2. Kydex plastic sheet, not to exceed 576 sq. inches total area, 24" maximum dimension, and not greater than 0.040" thick (1 mm).
3. ABS plastic sheet, not to exceed 576 sq. inches total area, 24" maximum dimension, and not greater than 0.0625" thick.
4. PETG sheet (aka Vivak® Copolyester Sheet) not to exceed 576 sq. inches total area, 24" maximum dimension, and not greater than 0.080" thick.
5. Polycarbonate glue/cement is allowed, only for the joining of polycarbonate pieces. Use of polycarbonate glues/cements may or may not be allowed in the pits at tournaments based on site-specific rules or requirements.
6. Aluminum sheet, not to exceed 576 sq. inches total area, 24" maximum dimension, and not greater than 0.0625" thick
7. Rope or cord any length, not to exceed 0.125" in diameter
8. Plastic-coated wire rope 0.03125" diameter or smaller. Compatible compression sleeves, clamps and hardware may also be used only in conjunction with the plastic-coated wire rope.
9. Non-Slip Pad, not to exceed 576 sq. inches total area, 24" maximum dimension (e.g. McMaster Carr Part #69275T54 or Home Depot SKU #134555)
10. PVC piping (of any schedule) 3" inside diameter or smaller, not to exceed 36" in total length
11. Commercial PVC couplings are not allowed.
12. PVC cement and cleaner (only for gluing PVC). Use of PVC cements and cleaners may or may not be allowed in the pits at tournaments based on site-specific rules or requirements.
13. Compatible mechanical fasteners (nuts, bolts, screws, etc.)
14. Mechanical fasteners may be secured using Loctite® or a similar thread-locking product. .
15. Rubber bands (size #32 or smaller, i.e. 0.125" thick & 3" in circumference)

16. Surgical Tubing 0.25" OD or smaller not to exceed 24" total length
17. Electrical tape and/or heat shrink tubing used only for insulation of electrical connections.
18. Universal Security Clips to hold PWM connections together, such as #2870 found at http://www.maxxprod.com/mpi/mpi-3.html
19. PWM extension cables. These cables may either be purchased from a vendor or fabricated by the team.
20. Any material strictly used as a color filter for a Light Sensor.
21. Hook and loop (e.g. Velcro, 3M Dual Lock) fastener may be used. The fastener may not be used as tape.
22. Non-Metallic Cable ties (also known as Zip Ties) up to 11" in length may be used.
