R203       *Design ROBOTS for safety and fair play. ROBOT parts shall not be made from hazardous materials, be unsafe, cause an unsafe condition, or interfere with the operations of other ROBOTS. Examples of items that will violate this rule include (but are not limited to):

A.      shields, curtains, or any other devices or materials solely designed or used to obstruct or limit the vision of any DRIVE TEAM members and/or interfere with their ability to safely control their ROBOT,

B.      speakers, sirens, air horns, or other audio devices that generate sound at a level sufficient to be a distraction,

C.      any devices or decorations specifically intended to jam or interfere with the remote sensing capabilities of another ROBOT, including vision systems, acoustic range finders, sonars, infrared proximity detectors, etc. This includes imagery on your ROBOT that utilizes or closely mimics 36h11 AprilTags,

D.      flammable gasses,

E.      any device intended to produce flames or pyrotechnics,

F.      hydraulic fluids or hydraulic items,

G.     switches or contacts containing liquid mercury,

H.     exposed, untreated hazardous materials (e.g., lead weights) used on the ROBOT. These materials may be permitted if painted, encapsulated, or otherwise sealed to prevent contact. These materials may not be machined in any way at an event,

I.        high intensity light sources used on the ROBOT may only be illuminated for a brief time while targeting and may need to be shrouded to prevent any exposure to participants. Complaints about the use of such light sources will be followed by re-inspection and possible disablement of the device,

J.      animal based materials,

K.      any device designed to damage or flip competing ROBOTS, and

L.      devices or conditions that pose an unnecessary risk of entanglement.
