Syllabus
Intro
LESSONS IN MAKING LASER SHOOTING ROBOTS
WHY LASER SHOOTING ROBOTS?
LESSON MAKE TEST CUTS ON PAPER/CARDBOARD BEFORE TRYING TO CUT YOUR FINAL MATERIAL
LESSON YOU CAN SUPERGLUE PULLEY BELTS! (AND THEY MOSTLY STAY TOGETHER...)
LESSON LASER CUTTING IS FUN!
LESSON COMMERCIAL WEBCAMS AREN'T WELL SUITED FOR STABLE MOUNTING. THE BEST YOU GET IS A TRIPOD SCREW MOUNT
LESSON USE LIMIT SWITCHES!!!
LESSON SUPERGLUE AND EPOXY ARE YOUR FRIEND (PARTS DONT ALWAYS FIT AS EXPECTED...)
TOLERANCES ARE IMPORTANT WHEN USING FRICTION DRIVE...
LESSON PRECISION MOUNTING OPTICS IS HARD
LESSON OPENBEAM IS AWESOME!
LESSON THE TSA DOESN'T ALWAYS CARE IF YOU HAVE LASER SHOOTING ROBOTS IN YOUR LUGGAGE
LESSON SOMETHING WILL USUALLY GO WRONG
