I don't know much about how you build your robots but making everything in 1/16 wall tubing instead of 1/8 will save a lot of weight and time(if you pocket 1/8). It is also stronger than pocketed 1/8 wall tubing. You can save a lot also if you use aluminum rivets instead of bolts whenever possible.Smaller wheels and custom gearboxes can save weight if done correctly(if you are unsuccessful in designing your own just copy our 2010/2011 gearboxes/drivetrain(link below)).
