Raul, on page 9 of 21 in the Kit of Parts Rules Section 5.3.1.4 <R70> Materials not allowed - "Materials classified as hazardous by their MSDS sheets." Looks like the Additional Materials list is wide open as long as <R68> "Additional parts must be generally avail. from suppliers such that any other FIRST team , if it so desires, may also obtain them at the same price." Also, must be able to fit into $3500 cost to build the robot. Looks like Carbon Fiber and Titanium may be legal this year, other than their cost. Hope this helps. Good luck this year! Can't wait to see what you guys dream up this year!
