All post-processed materials are allowed provided they are readily available to themajority of teams from standard distributers (e.g. McMaster-Carr, Home Depot,AndyMark , etc.). COTS parts and assemblies may only have a maximum of a single degree of freedom.

The following parts are LEGAL for the 2020-2021 FIRST Tech Challengechallenge. Assemblies of COTS components, such as linear slides, and gearboxes areallowed while a pre-fabricated gripper assembly designed to grab the game elements isnot. Holonomic wheels (omni or mechanum) are exempt from the one degree of freedomlimitation. Raw materials, and COTS may be modified (e.g. drilled, cut, painted, etc.) provided noother rules are violated.Revision 1: 7/14/2020Page 17
