Warlocks Materials Plastic Safety Man of Steel Glasses Smok’n Super Safety Geek! Plastic Safety Glasses Man of Steel Smok’n Nylon Noose to Drag Him Offstage Transparent Polycarbonate For Protection Cloak of Bronze Aluminum Diamond Plate For Solid Appearance Warlocks Imprinted with Brass Titanium Shoes (for Weight & Strength) with Rubber Soles so as not to damage carpet. Carbon Fiber Framework for lightness

Drill & Tap Tap Drill & Tap Dies are used to put threads on rods Why? Create your own screw hole in a slab of metal Hole is drilled slightly smaller than screw hole (use drill and tap sheet) and a tap cuts the grooves for the Screw. Literally, the tap threads the hole. Oil is used to lubricate while threading In and Out technique is used to clear metal out of tapped hole Dies are used to put threads on rods Same technique! Also, they make threaded rod. Tap

Tap & Die Sets Tap Set Tap and Die Set

Tape & Glue Tread on Wheels; Small Sensors etc. Tape Duct tape is not allowed on the robot to connect anything it is against FIRST rules. Electrical Tape is only allowed on a robot to insulate wires. Other tape is allow for decoration of the robot only. Adhesives (Allowed) Super Glue- Loctite Epoxy, 2 Parts Cement Hot Glue Tread on Wheels; Small Sensors etc.

Welding Aluminum Welded Frames are the typical technology used in constructing a robot for the following reasons: Removes Screws & Nuts from robot Removes Brackets from Robot Improves structural integrity- nothing gets loose Smaller aluminum tubing can be used while keeping equivalent strength Reduces weight up to 10 lbs. Improves look and perceived quality of workmanship.

Riveting Impacted by Rivet Gun Rivets Rivet Gun Cuts and Deforms Aircraft have used rivets since the 1920’s and 1930’s to improve aerodynamic performance while keeping the same structural integrity. Aircraft use aluminum and rivets just like Robots. (This is interesting?) Rivet Gun Cuts and Deforms Impacted by Rivet Gun
